Retroactive Recognition



You start watching a show. There's an actor on it. Let's call him Terry O'Quinn. As far as you know, you've never seen him before.

You keep watching the show.

Then you see an old rerun of The X-Files. There he is! Or you come upon the movie The Cutting Edge on cable. There he is! Or The Rocketeer. Or Heaven's Gate. Or that other episode of The X-Files he was in, playing someone else. Or Star Trek: The Next Generation, when he played that asshole admiral. Or JAG, where he played another admiral. Or The X-Files. Or the other 94 things he was in.

Point is, you've seen these things before. You just never paid enough attention to the actor to learn his name, or connect one appearance to another, until he finally landed a regular role on a series you regularly watch.

This is what happens when a former Hey, It's That Guy! finally lands a breakout role. It may also include a few minor roles before their Star-Making Role. When you just can't shake the image of the other roles, it's Role Association. If the older work is repackaged to accentuate the actor's later successes, it falls into Billing Displacement.

 * Ronny Cox has shown up as the villain in any number of movies, from RoboCop to Total Recall, but this editor never really put it together until seeing him as recurring character Senator Kinsey in Stargate SG-1.

 * Clint Eastwood first appears in an uncredited role as a lab technician in Revenge of the Creature, which appeared on MST3K. This is of course lampshaded by the guys, who jokingly pan Eastwood's performance and say "This is his first and last film!"

 * Jerome Flynn, who plays the sellsword Bronn in Game of Thrones, was previously a regular in the ITV series Soldier, Soldier. During that time, he also starred as one half of the English pop duo Robson & Jerome, who released a series of hit singles that were covers of Silly Love Songs. People who read up on the actor are often shocked when they discover him doing stuff like this.
 * Harrison Ford has said his early career was mostly spent playing "the guy who didn't do it" on various cop shows, before he hit it big with Star Wars. This also makes him a great subversion of Narrowed It Down to the Guy I Recognize these days.
 * He also had a minor role in American Graffiti.
 * Jodie Foster had a bunch of roles as a kid, before breaking out in Taxi Driver (while still a kid), e.g. Kung Fu, The Partridge Family, and The Courtship Of Eddie's Father. Plus of course being the Coppertone Girl.
 * She also had a voice acting role as the tomboy Anne Chan in The Amazing Chan and The Chan Clan

 * One of Michael J. Fox's first acting roles was a one episode gig on Beachcombers
 * Jason Frank appeared as a bully in an episode of Family Matters, a far cry from fighting evil space monsters as a Power Rangers. For that matter, fans of his current MMA career would probably get a good laugh out of the fact that he loses to Urkel in that episode.
 * Before he voiced a badass vampire and an overenthusiastic loyalist to a futuristic city-state, Crispin Freeman worked for Central Park Media, one of the premier dubbing companies in The Nineties, and his first official role was as the moody chimera Zelgadis in Slayers.
 * Even though the three actors playing the other three leads (Lisa Ortiz, Eric Stuart, and Veronica Taylor) were also breaking out at the time, all three of them would wind up working for the not-too-fondly thought of 4KidsEntertainment, as did most of the other actors who worked on Slayers; when CPM started to fall under, Freeman rose to stardom working for other companies dubbing more popular, un-Bowdlerised anime, mostly those licensed by Bandai Entertainment.

G-L

 * Fans of Alias can find Jack Bristow (Victor Garber) in the oddest places, including a few episodes of The Outer Limits, on the deck of Titanic, as a wellwisher in Sleepless in Seattle - and in one episode of Frasier as the eponymous character's very English butler. He even played Liberace and Ernest Hemingway in '80s biopics. Oh, and he was Christ in Godspell.
 * Sarah Michelle Gellar ate at Burger King.

 * Paul Giamatti had a minor role in the FMV videogame Ripper back when he was still an unknown. Ironically, said game had an All-Star Cast of people still fairly well known today meaning he ended up enhancing it over time.
 * Kathie Lee Gifford's first major role was a singer on Name That Tune.
 * Darla's victim in the opening scene of the Buffy the Vampire Slayer pilot was played by Carmine Giovinazzo of CSI: NY.
 * Carmine also guest starred on the season 2 ep "Revenge is Best Served Cold" on the regular CSI, two years before his casting in the spinoff. But Word of God says they weren't connected.
 * The fantastic Summer Glau, before becoming River Tam and Cameron from The Sarah Connor Chronicles, was also on an episode of Angel as a ballerina.
 * And on an episode of CSI as the crying best friend of a victim.
 * And in a Cold Case episode as the Victim of the Week.

 * She and her childhood friend, fellow future Disney Channel star Demi Lovato appeared together on Barney and Friends as young children.
 * It can be a severely weird experience to first see Matthew Goode as Adrian Veidt/Ozymandias in Watchmen and then later find him all over the place in quieter fare like Brideshead Revisited and A Single Man, or as the male lead in romantic comedies like Chasing Liberty. (The fact that his Watchmen role had him being stern, middle-aged and German-American in a very convincing blond wig when he and most of his other characters are affable dark-haired young Brits can make this even weirder.)
 * Betty Grable appeared in The Gay Divorcee as Edward Everett Horton's unnamed dancing partner, and was a chorus girl in several earlier movie musicals.
 * Aubrey Drake Graham was "Jimmy Brooks" on seasons 1-7 (2001-2008) of Degrassi. He now is known as the rapper/singer Drake.

 * She also had short-lived recurring roles on News Radio and Caroline in The City, and was also Benjamin Bratt's love interest in the two part Law and Order where they go to Los Angeles.
 * Seth Green in IT deserves a mention.
 * Really, watching It as an adult after having seen it as a child results in a massive bombardment of Retroactive Recognition.
 * As well as in My Stepmother Is An Alien, alongside future co-star Alyson Hannigan.
 * He also voiced a character in Batman the Animated Series.
 * And appeared in an episode of The X-Files and Enemy of the State

 * Kathy Griffin in Pulp Fiction. There's also Phil LaMarr, who played a minor character named Marvin known for getting shot in the face.
 * Greg Grunberg was in Hollow Man as a fairly major minor character. And in Lost he was the Pilot in the Pilot.
 * He also had a recurring role in Felicity.
 * And let's not forget about a minute of screentime in Baseketball as a rival player in the baseketball league.
 * A very young Jake Gyllenhaal as the son of a Victim of the Week in a Homicide: Life On the Street episode (2x01) directed by his father.
 * He also played Billy Crystal's son in the City Slicker movies.
 * Journeyman supporting actor/Saturday Night Live standout Bill Hader was a field agent on Punk'd. Avid viewers of the credits of action films (all two of you) may also spot his name as a production assistant on a host of early-2000s films like Collateral Damage and The Scorpion King.
 * Long before he became a household name, Tom Hanks appeared in the 1980 slasher flick He Knows You're Alone.
 * People familiar with Hanks as blockbuster movie actor would probably have this reaction to his role in Bosom Buddies.
 * Alyson Hannigan as Dan Aykroyd's daughter in My Stepmother is an Alien.
 * Mark Harmon showed up in The West Wing as CJ's Bodyguard Crush during season three. The character was... rather reminiscent of Gibbs.

 * Teri Hatcher was a "Mermaid" (showgirl) in the final season of The Love Boat.
 * Ray Tango's younger sister in Tango and Cash, a spunky sidekick on reruns of MacGyver, manned the transporter in an episode of Star Trek the Next Generation, and a Girl of the Week on Seinfeld
 * And she was Sam's ex in Quantum Leap, though he changed history and got her in the end.
 * Keeley Hawes shows up in the two-part finale of The Vicar of Dibley and the voice of a certain female archeologist...
 * Of course, before then she was best known for being a regular on Spooks. Funnily enough, in The Vicar of Dibley, she plays Richard Armitage's sister, who would go on to be in Spooks.
 * Lena Headey played a mousy new teacher in the 2007 film St Trinian's, and Lizzie in The Remains of the Day. She keeps her actual accent in both, though. And you might also recognise her as Queen Gorgo in Three Hundred.
 * In the Highlander episode "Nowhere To Run", Anthony Stewart Head (credited as Anthony Head) plays an ambassador and friend of Duncan MacLeod. This is the same episode that features Marion Cotillard in her first ever acting role.
 * Audrey Hepburn's silent appearance in the opening scene of The Lavender Hill Mob. The same year she instantly became a smash success with Roman Holiday.
 * There is much mockery to be made of future Oscar winner Phillip Seymour Hoffman's supporting role in Twister.
 * Laurie Holden is well-known these days for her roles in The Shield and The Walking Dead, but she had a number of guest appearances (including many Canadian series) long before then:
 * She played a young girl in an episode of Captain Power And The Soldiers Of The Universe.
 * A guest spot on an episode of Murder, She Wrote.
 * As the shadowy Marita Covarrubias in several episodes of The X-Files.
 * Josh Holloway, like co-star Terry O'Quinn, had a fair number of credits before Lost, such as episodes of CSI, NCIS, and Angel. He's also in the video for Aerosmith's "Cryin'" as the guy who breaks Alicia Silverstone's heart.
 * Gabriel Iglesias was on All That for a season several years before Comedy Central specials and Last Comic Standing made him widely famous.
 * Jeremy Irons appeared on Play Away, a BBC children's show, in the 1970's. It often crops up in 'before they were famous' clip-shows in the UK.
 * Samuel L. Jackson holds up a Burger Fool in Coming to America, and has his ass handed to him by Eddie Murphy, of all people.
 * He also appears very briefly in Mean Streets, where he's slapped around by Robert De Niro and Harvey Keitel. He isn't even credited for this on IMDB.
 * He also plays a lawyer on a Season 1 episode of Law and Order... defending Philip Seymour Hoffman, no less.
 * Stephanie Jacobsen had a tiny role in the Farscape episode "Incubator" as one of Scorpius's nurses/"assistants", years before her prominent genre roles as Kendra in Battlestar Galactica and Jesse in The Sarah Connor Chronicles.
 * It's a little creepy to watch Famke Janssen pursue a romantic relationship with Jean-Luc Picard 8 years before hanging out with Professor X at the Xavier Institute for Higher Learning.
 * Scarlett Johansson, usually playing someone’s sister, in many a crappy 90s film. Including North and Home Alone 3 .
 * Turns out Cherry Jones (aka President Allison Taylor) played politician Barbara Layton in an episode of The West Wing in 2004. Probably averted for Broadway theatre-goers, as by the time she had already been a huge name on it for years, had won one Tony award and was on the cusp of another for her role as Sister Aloysius in Doubt.
 * Milla Jovovich was Parker Lewis' female target in the series pilot.
 * And a French foreign exchange student in an episode of Married With Children.
 * As Wil Wheaton regularly reminds us, he got some lip action with a pre-famous Ashley Judd in an ep of TNG.
 * Tim Kang acted in a ton of commercials (for Cingular, Home Depot and Dairy Queen) before landing the role of Agent Cho on The Mentalist. He also had a small role on The Sopranos, seen here.
 * Stana Katic of Castle once had a bit part as a flight attendant on Alias.
 * And as Officer Morgenstern (she of the BFG) in The Spirit.
 * It's a bit of a shock to watch old episodes of Desmonds, and realise that the Token White loser wideboy is Dominic Keating from Star Trek Enterprise.
 * DeForest Kelley was in a black-and-white Perry Mason episode.
 * And Gunfight at the OK Corral, which was alluded to in the episode "Spectre of the Gun" in an illusion.
 * The 1956 novel The Last Hurrah, which was very loosely based on real events in early 1950s Massachusetts politics, features a character named Kevin McCluskey, who is a telegenic but politically inexperienced candidate with a fancy education, a pretty wife, smiling kids, a respectable war record from his days in the Navy, and more good looks than brains. Reading the book anytime after 1960, the character seems strangely familiar...
 * Ben Kingsley showed up on the BBC's Playing Shakespeare in the late 1970s.
 * 9 year old Keira Knightley played a pre-teen runaway on an episode of The Bill (as seen in this screencap).
 * Not to mention her appearance in the 1999 Oliver Twist miniseries as Rose Fleming, where she looks about 3 years older than her actual age of 14.
 * And her appearance as the slutty friend in The Hole, made memorable by the fact that she takes her top off.
 * Jane Krakowski, aged 16, appears in the opening moments of Fatal Attraction as the Gallaghers' babysitter.
 * Before he was the main character in Numb3rs, David Krumholtz was the dorky Jewish kid Joel who had a crush on Christina Ricci's Wednesday Addams in Addams Family Values.

 * And the very mature and sexy Ephram's girlfriend in Everwood.
 * And Rachel Meyers in Saved by the Bell: The New Class.
 * Before The Human Centipede, Dieter Laser played Mantrid in Lexx, serving as the Big Bad for Season 2.
 * In Friends, Hugh Laurie was on the plane Rachel boarded to London. And he called her out on her shit.
 * He also played Jasper in the Live Action Adaptation of One Hundred and One Dalmatians. In one scene, he gets outsmarted by a raccoon into getting caught on electrified barb-wire.
 * He had already a decades-long career on the other side of the Atlantic, though. For people who know their Blackadder Hugh Laurie's cameo in Friends was just that... a celebrity cameo.
 * One of the great things about that episode was that they went to the bother of getting guest appearances from Hugh Laurie, Jennifer Saunders, Tom Conti, and Olivia Williams. To the show's key demographic of young Americans: meaningless nobodies. To the show's British audience: a delightful treat.
 * He's also a hapless random French court official in The Man in the Iron Mask, who gets executed on a whim by Leonardo DiCaprio's King Louis.
 * He was also the bumbling policeman that John Goodman kept arguing with throughout The Borrowers.
 * And was Stuart Little's adoptive dad in the live-action movies.
 * Mr. Palmer in Sense and Sensibility.
 * Hugh Laurie really isn't such a great example of this trope - he might not have been a household name (no pun intended) before he became a certain grouchy doctor but as evidenced by the movies above, none of which are direct-to-TV stuff, he certainly got a fair old amount of acting work in Hollywood and as also mentioned above, he was extremely well known in the UK. As well as Blackadder, he was also Stephen Fry's comedy partner for a number of years, with shows like Jeeves and Wooster and A Bit of Fry and Laurie.
 * Incidentally, both he and Stephen have been asked a few times if the latter will ever pop up in House. They've said the only way they'd like to do it is if Stephen played a character that is even brighter than House, possibly House's mentor at med school or something. Yes, they want Stephen to play Mycroft to Hugh's Sherlock.
 * Before Taylor Lautner was in Twilight, he was a junior world champion karate master, having gotten his black belt by age eight. He competed in an ISKA event at age 11 that was taped by ESPN, which a few years later (but still before Twilight) was riffed on Cheap Seats.
 * He was also Sharkboy in The Adventures of Sharkboy and Lavagirl, which is just as awful as it sounds.
 * Adam Lazare-White, voicing Jacob from Mass Effect 2, should sound familiar to older gamers that have memories of video gaming later in The Nineties. He played 1LT Terrence "Zero" O'Hearn in Wing Commander Prophecy and provided the character's voice in the sequel, Wing Commander Secret Ops.
 * Matt Le Blanc of Friends fame had his first big break on the short-lived Fox sitcom Top of the Heap, a Spin-Off of Married With Children, along with Joey Lauren Adams.
 * He also played the same character in a few episodes of Married With Children and in another show called Vinnie & Bobby.
 * Heath Ledger as Patrick in Ten Things I Hate About You.
 * Though this was more of a Star-Making Role - he parlayed this into more serious fare.
 * Pictured above, Bruce Lee playing Kato in the Adam West Batman series for three episodes. This was before his first film by three years.
 * Technically, that was a crossover. The Green Hornet series ran alongside Batman for one season, with Kato being the only redeeming quality of the show.
 * Ken Leung was a mutant in X Men the Last Stand, and kidnapped the girl from Rush Hour.
 * Not to mention Dong! (rhymes with flong).
 * Even Evangeline Lilly can invoke this, despite having next to no acting experience with dialogue prior to starring in Lost. She worked in Vancouver for a while as a part-time model and would occasionally appear as a mute extra in tv series filmed there, notably in Smallville, where she managed to be in 5 episodes. So if you go on a Smallville binge, expect several moments of, "Hey! Did Kate Austin just walk past the screen?!"
 * Chad Lindberg, aka Ash, the computer genius, from Supernatural, started his computer training early: he shows up in the first-season Buffy the Vampire Slayer episode "I Robot, You Jane."
 * Sam Lloyd took away Drew's Batmobile and was the Neighborhood Association President in Malcolm in the Middle before becoming Ted Buckland.
 * Carl Lumbly played a South African Embassy staff in The X-Files before starring in Alias.
 * Jane Lynch has had a whole bunch of small or supporting- yet almost always scene stealing- parts in various movies and TV shows before becoming beloved the world over as Sue Sylvester in Glee.
 * She was also Dr. Wahler in The Fugitive
 * She was Spencer Reid's mentally ill mother on Criminal Minds
 * She was the store manager in The 40-Year-Old Virgin.
 * She was Julia Child's sister in Julie and Julia.

M-R

 * Also, he's the Hitchhiker at the beginning of Fear and Loathing in Las Vegas.
 * Tina Majorino, probably best known for her role as Deb or as Mac, is the MacGuffin Girl in Waterworld.

 * Costas Mandylor had guest appearances on Sex and the City and Charmed before becoming Hoffman in Saw.
 * Vincent Martella, who is the voice of Phineas in Phineas and Ferb, was Greg in Everybody Hates Chris. Sort of an inversion, because Phineas and Ferb started in 2007 and Everybody Hates Chris didn't end until 2009.

 * Also appeared for five seconds in Sex and the City when they went to L.A.

 * Vic Mignogna voiced minor Tournament Arc villain Uraurashima in the dub of Yu Yu Hakusho, using something very close to the voice he would later use in his breakout role as Edward Elric.
 * Monster of the Week on Buffy the Vampire Slayer turned most hilarious when Wentworth Miller of future Prison Break fame played a swimmer-turned-sea-monster; * creepy voice* fiiiiiiiiiish!
 * Alfred Molina was Indiana Jones' treacherous guide Sapito in the beginning of Raiders of the Lost Ark. At one point, he even has spiders crawling all over him.
 * And Betty Mahomoody's Dr. Jerk of an abusive husband in Not without my daughter.
 * Julianne Moore as Marlene, Claire's friend in The Hand That Rocks the Cradle
 * A suspicious Chicago doctor in The Fugitive.
 * Viggo Mortensen has a nonspeaking role as an Amish farmer in Witness.
 * And played Satan in The Prophecy.
 * Joe Morton, before playing Henry Deacon, the Mechanic-turned convict in Eureka, played Scratch's number two in the classic film Crossroads. He transports them to the guitar head-cutting contest against Steve Vai, who plays Jack "Devil Boy" Butler, the one person Eugene Martone, King of the Hobos has to actually fight.
 * Also in the early nineties he was involved in some cutting-edge cybernetics research as Dr. Miles Bennett Dyson.
 * He was also the first Dr. Hamilton in Smallville. (They've since decided that he's a Dr. Hamilton and not the Dr. Hamilton, who was a Recurring Character.)
 * Also played a Senator who was left at the altar by Whitley Gilbert
 * And as a hard-ass military man in John Sayles' Lone Star
 * Brittany Murphy was a regular in The Torkelsons revamp, Almost Home. She also guested several times in the first season of Sister Sister.

 * Krull features Liam Neeson in a minor role.
 * Also, The Mission.
 * Eric Nelsen, who played Zeke in the "iDream of Dance" of iCarly, later played the Jerk Jock Brett in Thirteen.
 * Famously, Jack Nicholson's debut was a bit part as a masochistic dental patient in the original Little Shop of Horrors.
 * And now he gets first billing on the DVD box.
 * He also turns up, equally unrecognizable, in several other Roger Corman movies before his breakthrough role in Easy Rider, including The Raven, where he typically does lose first billing to the all "star" cast of Vincent Price, Peter Lorre, and Boris Karloff.
 * John Noble in an episode of Stargate SG-1, now known for his role on Fringe.
 * And his role as Denethor in The Lord of the Rings.
 * Renee O'Connor, of Xena: Warrior Princess fame, had a small role in The Adventures Of Huck Finn, starring Elijah Wood.
 * She is also in the second Hercules: The Legendary Journeys Pilot Movie as Deianira.
 * She played a waitress in one of the Darkman movies--the second one I think.
 * One for lefties - Lawrence O'Donnell Jr. was a producer on The West Wing and played President Bartlet's father in a couple of episodes. Now? "Hey, it's Keith's guest host!"
 * Masi Oka, best known as the Adorkable Hiro Nakamura from Heroes, had previously played Franklin on Scrubs and had a bit part in Austin Powers where he insisted the monster was most definitely not Godzilla.
 * Alex O'Loughlin had the memorable role of the obsessive-compulsive serial killer who tries to redeem himself by helping the blind son of one of his victims on an episode of Criminal Minds.
 * Terry O'Quinn from Lost. Part of the failure to recognize can be attributed to slightly altered appearance for the role of Locke. In most other roles, he sported a mustache and balding hair, rather than a totally shaven head.
 * He was also a dickish Starfleet admiral in an episode of TNG.
 * Don't forget the original (I.E. "better") version of The Stepfather!
 * And Howard Hughes (yes, THAT Howard Hughes) in The Rocketeer.
 * Emily Osment in an episode of Friends.
 * She also played Cassie in one of the Sarah Plain And Tall movies.
 * She also appeared on 3rd Rock from the Sun, and played Gerti Giggles in the second and third Spy Kids movies.
 * Haley Joel Osment may be most famous for seeing dead people who don't know they're dead, but he made his film debut in Forrest Gump as.
 * He and Jonathan Lipnicki played the sons on The Jeff Foxworthy Show.
 * In 1962, Kerry Wendell Thornley wrote a Roman à Clef called The Idle Warriors about a strange young man he had known while in the United States Marine Corps. His name? Lee Harvey Oswald. For those who don't know, that's one year before the Kennedy assassination.
 * Jared Padalecki was a fifteen-year-old in a car crash on ER.
 * And one of the bullies in Cheaper By the Dozen.
 * And Dean in Gilmore Girls.
 * Keke Palmer from Akeelah and the Bee and True Jackson VP was Madea's young troubled foster child in Madeas Family Reunion.
 * Gwyneth Paltrow played the younger version of Wendy in Hook.
 * It's startled quite a few people watching reruns of Law and Order Special Victims Unit when they see Hayden Panettiere in an episode as a highschool prostitute.
 * Either inverted or played straight with Grace Park, who plays GDI's Lt. Sandra Telfair in Command and Conquer Tiberium Wars. People might recognize her for her previous role as Number Eight on Battlestar Galactica Reimagined, or for her current role as Kono on Hawaii Five-0.
 * Before Legend of the Seeker, Craig Parker played Haldir, a minor elf in The Lord of the Rings.
 * Jim Parsons, now known as Sheldon Cooper on The Big Bang Theory, played Tim, the Klingon-speaking "fast-food knight" in Garden State.
 * He was also raised by wolves.
 * Simon Pegg appears as an Easy Company NCO in Band of Brothers.
 * That's yet another case which is location-specific - he was already known as a comic actor/writer in the UK by then, though admittedly not as instantly recognisable as he is now.
 * So you're watching Breakfast at Tiffany's, and Audrey Hepburn's Love Interest seems bizarrely familiar, and you don't know why. Then you realize that if he was aged up about twenty years and given white hair...Dear God, it's a young Hannibal! (George Peppard)
 * Matthew Perry. Before Friends, he had guest spots on a dozen prime time shows, plus a few failed series. Many fans didn't immediately recognize Chandler as Carol's dead boyfriend from Growing Pains.
 * His first big break was in a Fox sitcom initially called "Second Chance," then re-tooled as "Boys Will Be Boys," minus the original version's supernatural elements.
 * Or Brandon's suicidal classmate in Beverly Hills, 90210.
 * Robert Picardo appeared in Innerspace.
 * He was also the guy Rodney Dangerfield's wife is sleeping with in Back to School. And the Obstructive Bureaucrat in Gremlins 2. The impressive head of hair can make him hard to recognize.
 * One of the ickier episodes of Law and Order revolves around two sisters, one killed by a serial rapist, the other narrowly surviving, turning out to be in league with the killer. Say hello to Ellen Pompeo, best known as Meredith Grey.
 * Markie Post was a behind-the-scenes lady on the 1970s game shows Split Second and Double Dare 1976 (a quizzer, not the kids' stunt show), and later a card dealer on Card Sharks, before her breakthrough role on Night Court.
 * Zachary Quinto, who is Sylar from Heroes and Spock in the 2009 Star Trek movie, played a demon in Charmed.
 * And prior to both, he hilariously hammed it up playing Tori Spelling's Gay Best Friend on her show So Notorious. Watching that show and then Heroes back to back makes for an especially hilarious experience.
 * And he was the forgettable Adam Kaufman in season 3 of Twenty Four.
 * Following from 24, TJ Ramini gets some billing as Tarin Faroush, but will be more recognised among British audiences as DC Zain Nadir, one of the more famous characters of The Bill.

 * Ryan Reynolds was in the original pilot movie for Sabrina the Teenage Witch
 * Also was in Two Guys, a Girl And A Pizza Place together with Nathan Fillion.
 * Popped up in a season 3 episode of The X-Files.

 * Wayne Robson. You know Mike Hamar, the ex-con on The Red Green Show? Did you notice him in One Magic Christmas? How about the Disney TV Movie Murder She Purred? Cube? Welcome To Mooseport? The Rescuers Down Under?
 * How about Popeye?
 * Daniel Roebuck, Artz from Lost has been everywhere!
 * Seth Rogen appears as a bully in Donnie Darko. He utters the line "I like your boobs"
 * Before that he had fairly large roles in Freaks and Geeks and Undeclared.
 * Tim Russ aka Tuvok was the black Spaceballs who "ain't found shit!".
 * He was also one of the crooks in the Star Trek the Next Generation episode "Starship Mine." He has the Vulcan nerve pinch used on him by Picard.
 * He's also a bridge officer on the Enterprise-B at another point. We get a good look at his ears and they're not pointed.
 * Interestingly he was retconned in a Voyager episode to actually BE Tuvok (complete with pointed ears in a flashback) as a lieutenant on the Excelsior who had joined starfleet in Kirk's era only to become disillusioned by Sulu's maverick attitude, quitting Starfleet for decades until rejoining in Picard's time.
 * Debra Jo Rupp aka Kitty Forman was Josh Baskin's secretary, Miss Patterson, in Big.
 * And Jerry Seinfeld's long-suffering (not that she didn't deserve it) agent. And the biological mom of Phoebe Buffay's babies.
 * Tim Robbins appears in a 1st season episode of Moonlighting as an assassin that underestimates an old man and is Curb Stomped with a bedpan.
 * Top Gun had a pre-breakout Meg Ryan in it.
 * And don't forget the above Tim Robbins as Merlin.

S-Z

 * Katee Sackhoff got beheaded in Halloween: Resurrection and was on one season of MTV's Undressed before she became Battlestar Galactica Reimagined's Ace Pilot Starbuck.
 * Adam Sandler was one of Theo's buddies in The Cosby Show.
 * He also played Colin Quinn's "delinquent cousin Stickpin" and "The Stud Boy" in Remote Control.
 * Peter Sarsgaard in The Man in the Iron Mask, playing a romantic rival to Leonardo DiCaprio and a doomed son to John Malkovich. Undoubtedly he was chosen because of his speaking voice, which uncannily matches Malkovich's, even though nobody else in the film bothers to match accents.
 * David Schwimmer made minor appearances on The Wonder Years and Blossom before landing his most famous role as Ross Geller.
 * Hey, did you know Tony Shalhoub, TV's Monk, played the guy who set up the "borrowed ladder" deal between Jerome and Vincent in Gattaca?
 * Tony Shalhoub guested in a lot of stuff - The X-Files, Jeebs in Men in Black, Galaxy Quest, the Thirteen Ghosts remake.
 * Hell, he even had his own sitcom (with Neil Patrick Harris) Stark Raving Mad.
 * Although it doesn't seem to work if you were a fan of Wings.
 * He also sings "Macho Man" with Joan Cusack in Addams Family Values.
 * He's near unrecognizable as an incompetent producer in Barton Fink.
 * Rondell Sheridan was Andre in Cousin Skeeter before becoming well known to kids as Victor Baxter.
 * John Simm was in Spaced and Human Traffic before Life On Mars.
 * Kurtwood Smith (Red) can have this too, in films such as RoboCop and Deep Impact.
 * Not to mention as the President of the Federation in Star Trek VI the Undiscovered Country.
 * And he was Neil's father in Dead Poets Society. This is actually what makes  go from Tear Jerker to Narm, though.
 * Matt Smith shows up in a deleted scene of In Bruges as a younger, flashback version of Ralph Fiennes' character.
 * Matt Smith didn't exist in the public eye until Doctor Who. His IMDB page was practically empty up until this year.
 * He was in an episode of Secret Diary of a Call Girl to have a one night stand with Rose Tyler
 * Much in the same vein he played her best Friend in the Made for TV adaptation of Sally Lockhart.
 * Cobie Smulders was a Psycho Ex-Girlfriend of Lex Luthor on Smallville. "Lex go to the mall today!"
 * Ian Somerhalder played a Recurring Character for half a season on Smallville, as The Mole whom Lana Lang dates. One of his episodes even features his future co-star Evangeline Lilly (see folder G-L above). They even appear together in the same shot.
 * He also was on Young Americans and in Tell Me You Love Me.
 * In an episode of Cheers, Diane serves on a jury and manages to get the defendant to break up with his girlfriend when he comes into the bar. The man looks uncannily like a flesh-colored Data.
 * What's funny about Brent Spiner is how many of his roles are comedic-ish... Data's the exception, not the rule. The rule is closer to Arik Soong.
 * Though he does appear in an episode of Law and Order: Criminal Intent as a creepy therapist.
 * Then there are those episodes of Night Court with the hillbilly family. Take a look at the man in that family....
 * Spiner played another comedic hillbilly as a rural preacher in the Tales from the Darkside episode "A Case of the Stubborns".
 * Cole Sprouse played Ben in Friends, and he and his twin Dylan Sprouse had a part in an episode of That 70s Show before both of them landed on The Suite Life of Zack and Cody.
 * And together, they also played the part of Julian "Frankenstein" McGrath in Big Daddy.
 * Another one for Higher Ground: Jewel Staite.
 * And again, she was on The X-Files. Seems like that show nurtured rather a few budding actors...
 * And before that, she was rainbow-haired Catalina on Space Cases.
 * Way back in 1996 she was Becca, the best friend and neighbor of Ben Foster's Tucker on the Disney Channel show Flash Forward.
 * Don Stark aka Bob Pinciotti appeared as holographic gangster Nicky the Nose in Star Trek First Contact.
 * He also had a role in Santa with Muscles.
 * Kristen Stewart in Panic Room. Weird to look back on it years later, since she was 10 when the movie was made.
 * She also shows up at the very end of Jumper, as the protagonist's half-sister.
 * In Zathura as the sister.
 * Also in Catch That Kid, which also has Retroactive Recognition of Corbin Bleu and Max Thieriot.
 * Immediately pre-breakout, she played the underage love interest in Into the Wild.
 * She also stars in the 2004 movie Speak (based on the novel of the same name), being 13 years old at the time.
 * Patrick Stewart appeared in the BBC educational show Playing Shakespeare in the 1970s before becoming Captain Jean-Luc Picard.
 * He was Leondegrance in Excalibur. Said film also had Liam Neeson (Gawain), Helen Mirren (Morgana), and Gabriel Byrne (Uther Pendragon).
 * He also played Gurney Halleck in Dune.
 * David Suchet was in the same.
 * An actor named Woodrow Strode played the King of Ethiopia in The Ten Commandments. In a later scene, he doubled as a royal slave. Years later, Mr. Strode became mildly well known. This led viewers of Mr. DeMille's epic to conclude that Rameses enslaved the Ethopian king.
 * David Suchet played the rival Arab dictator in the first Iron Eagle movie.
 * Faran Tahir, prior to becoming Raza or Captain Robau, combined this with You Look Familiar by appearing as two separate characters on Twenty Four - in the second season he was a mosque greeter, and in the fourth season he was a Turkish terrorist on the receiving end of the Jack Bauer Interrogation Technique.
 * Amber Tamblyn was one of Dawn's friends in the sixth season of Buffy the Vampire Slayer.
 * Amanda Tapping showed up in an episode of Due South a year before Stargate SG-1 aired, playing a scientist with a secret government program that was strongly implied to be tracking UFOs.
 * Catherine Tate shows up in an episode of Men Behaving Badly as a woman interested in buying Tony and Gary's flat.
 * How about John Terry (Christian Shepard), who played Felix Leiter in The Living Daylights? Oh yeah, and his first-ever film role as Hawk the Slayer.
 * Leon Thomas is well known as Andre on the Nickelodeon show Victorious. You might've seen the seventh episode of the second season of another Nick show, Just Jordan two years before that. Watch it present-day and you'll recognize Ronnie as a young Leon Thomas.
 * Sam Trammel plays the upstanding owner of a popular bar in True Blood, but way back when in the second episode of Dexter he played a drunk with a persistent hit-and-run problem..
 * John Travolta (Creator)'s first role was in the horror movie The Devil's Rain. He yells "Blasphemer!" and falls down the stairs, and the protagonists see the flashback inside his eyes.
 * Many young people would be surprised to see him in reruns of Welcome Back, Kotter.
 * And after that, playing Billy, Chris' boyfriend in Carrie.
 * A young Keith Urban appears in the 1992 video for Alan Jackson's "Mercury Blues". Most Americans probably didn't recognize Urban's face until 1999.
 * In Rudy, Vince Vaughn has a minor part as Jamie O'Brien, the under-performing halfback who.
 * Before she became Major Kira on DS9, Nana Visitor drilled for oil in a season 1 episode of MacGyver.
 * In Tank Girl, a lot of viewers have had this with Naomi Watts.
 * Before playing Tony DiNozzo on NCIS Michael Weatherly was a one-episode character on Charmed.
 * Game show announcer Randy West, despite not having a familiar face, was a contestant on several shows before his announcing career began. Among these were All Star Blitz, Hit Man, and Press Your Luck.

 * Speaking of Wheel, Alicia Witt was a contestant on a teen week in 1989. (Incidentally, she later played a Celebrity Edition in 1997.)
 * Her first acting role, at the age of nine, was Alia in David Lynch's Dune.
 * Before her breakout job as a regular on Saturday Night Live, Kristen Wiig played "Dr. Pat" on the first season of The Joe Schmo Show.
 * Mark "Arthur Weasley" Williams teamed up with Hugh Laurie in the Live Action Adaptation of One Hundred and One Dalmatians.
 * He was also a goofy exterminator in The Borrowers, where Hugh Laurie was a rambling cop and Tom Felton (Draco Malfoy) was the son in the family of Borrowers.
 * Speaking of Williams, watch the first two seasons of Red Dwarf. He was Olaf Petersen. He's very good in bed.
 * And then my son helped vanquish the Dark Lord. Which was nice.
 * Really, this is similar to the Hugh Laurie example above. Both men had large parts on comedy shows which were huge in the UK (The Fast Show might not have been quite as big as Blackadder, but it was still very popular) - it's just that they didn't necessarily become household names in the States until they took on one particular role.
 * Same-TV-show example: Before Michael Wisher was the first actor to play Davros on Doctor Who, he had a fairly minor role as a broadcaster in "The Ambassadors of Death," five years earlier, and then another role the next year.
 * He also provided may Dalek voices before playing Davros.
 * Elijah Wood was one of the kids that Marty meets in an arcade in 2015 Back to The Future Part II. He even spoke.
 * He also had a part as a stressed-out child business man in the Paula Abdul video Forever Your Girl (He appears almost 2 minutes in).
 * He's one of the main characters in Deep Impact, but he still wasn't recognizable to most people until a bit later.
 * Anton Yelchin played a troubled teenager in the Criminal Minds episode "Sex, Birth, Death" several years before he played Chekov in the Star Trek Continuity Reboot.
 * He also plays the main child character in the film version of Hearts In Atlantis.
 * Billy Zane, who played Cal in Titanic was Match, one of Biff Tannen's Mooks in the first two Back to The Future movies.
 * And in between he was The Phantom.
