Separated At Birth Casting



Sometimes, casting directors are called upon to cast, say, a father and son, or two brothers, or a younger and older version of the same character. And sometimes, they find someone that looks so uncannily like the original actor that it comes as a surprise to the viewers that the two aren't actually related.

Not to be confused with Real Life Relative, which is when the actors actually are related, and playing relatives.

Film

 * In Big Fish, Alison Lohman was cast (assisted by makeup) as the young version of Jessica Lange.
 * Supposedly, Ewan McGregor was cast by Tim Burton because he uncannily resembled Albert Finney when he was younger.
 * By McGregor's own recollection he saw a photo in Tim Burton's office of Albert Finney in Tom Jones and was trying to remember which photoshoot of his it was taken from before he realised that it wasn't a photo of him at all.
 * Mayim Bialik as the younger version of Bette Midler's character in Beaches.
 * Harrison Ford recommended River Phoenix for young Indiana Jones in The Last Crusade movie specifically because he reminded him of himself at that age.
 * Rachael Leigh Cook as the young Parker Posey in the movie adaptation of The House of Yes.
 * The boy chosen to be a young John Cusack in Hot Tub Time Machine.
 * Tenacious D in The Pick of Destiny: Young JB.
 * Apparently, though he's pretty much an extra in Star Wars: Revenge of the Sith, Tarkin appears largely due to the fact that they found an actor with an astonishing resemblance to Peter Cushing and couldn't bear to not cast him!
 * The actor was Wayne Pygram, most well known as Scorpius from Farscape. And he was made up to look ASTONISHINGLY like Peter Cushing.
 * Similarly, actress Genevieve O'Reilly was cast as Mon Mothma due to bearing a striking resemblance to Caroline Blakiston. Sadly, as her speaking role was cut, she too is largely an extra.
 * Also from the prequels, The Phantom Menace would just have Natalie Portman Acting for Two. Then they discovered Keira Knightley and [[media:rsz_natalie_vs_kiera_4928.jpg|put her as the queen's decoy]].
 * Mila Kunis portrays a young Angelina Jolie in Gia. It's downright freaky.
 * While filming Water for Elephants, actor Hal Holbrook (who plays an older version of the character Jacob Jankowski) came up to Robert Pattinson and told him "My God, you look like me as a young man!"
 * In Never Let Me Go, the kids who play the young version of Cathy, Ruth and Tommy look eerily like the older actors, particular Keira Knightley.
 * In Thor, Dakota Goyo & Ted Allpress, who play the young Thor & Loki, strongly resemble the actors who play their adult versions, Chris Hemsworth & Tom Hiddleston.
 * Reuben Langdon has been Gideon Emery's stunt double on multiple occasions, such as in the movie Takers. They look like they could be twins!
 * Christa B. Allen looks so much like a young Jennifer Garner that she has played a younger version of her in two movies, Thirteen Going On Thirty and Ghosts of Girlfriends Past.
 * Malese Jow looks so much like Miranda Cosgrove that Malese was chosen to play Carly's lookalike in "iLookalike".

Live-Action TV

 * On Glee:
 * A flashback depicted Kurt as a young adolescent. The actor chosen to portray Chris Colfer's character Kurt bears an uncanny resemblance to a younger Chris Colfer (as pictured above right).
 * Adam Kolkin is set to play young Colfer again in Struck by Lightning.
 * The character of Shelby Corcoran (portrayed by actress Idina Menzel) is the mother of the character Rachel Berry (portrayed by actress Lea Michele). Menzel was presumably cast due, in part, to her striking resemblance to Michele.
 * Younger versions of Sam and Dean of Supernatural nicknamed the Weechesters tend to look quite a bit like them, especially when the age gap is smaller. It's not incredibly hard to find a mop-top and chisel-chest, but it helps when they actually get the demeanors down too.
 * The character of Niles on Frasier was created after producers noticed David Hyde Pierce's uncanny resemblance to Kelsey Grammer.
 * While not necessarily intentional, John Mahoney bears a resemblance to the two as well.
 * Ant and Dec have Little Ant and Dec (their variety show Ant and Dec's Saturday Night Takeaway had trotting out "little [insert name here]" versions of various guests as a feature, including Little Little Ant And Dec).
 * The Mitchell brothers in Eastenders.
 * Jamie Walters as the younger version of Dean Stockwell's character in Quantum Leap.
 * In the made-for-tv film Hawking, Stephen Hawking (Benedict Cumberbatch) and the actors who play his parents seriously look like they could actually be related.
 * Lori Loughlin and Shenae Grimes on 90210 play a mother and daughter that actually look alike.
 * Gene Wilder had a short-lived sitcom called "Somehing Wilder" in the mid-Nineties where he played father to two little boys. One of whom was virtually a miniature clone of him.
 * The brothers Hank and Evan on Royal Pains.
 * Lachlan Nieboer, who played Gray, Jack Harkness's brother on Torchwood, looked and sounded like a younger version of John Barrowman, despite not being related.
 * On Once Upon a Time Ginnifer Goodwin from Big Love and Jennifer Morrison from House, two actresses who for years people have said shared a resemblance and have often been confused with each other, are now playing mother and daughter.
 * Bailee Madison played Goodwin's character as a child and the actress could easily pass for Goodwin's daughter or young sister. She also nailed some of her mannerisms.
 * The boys playing a young Earl and Randy on My Name Is Earl.
 * Victor Garber and Jennifer Garner as father and daughter on Alias.
 * Charisma Carpenter and Alexandra Chando on The Lying Game.
 * Elizabeth Penn Payne, the Masked Woman (aka ) on Ugly Betty has nearly the exact same eyes as.
 * On Eight Simple Rules, Martin Spanjers and Amy Davidson, who play brother and sister, look like they actually could be (contrast Kaley Cuoco as their other sibling, who looks nothing like them or either of the parents: John Ritter and Katey Sagal).
 * Creepily averted on Full House; here all three kids look more like Dave Coulier, who plays the unrelated Joey, than either Danny (their father) or Jesse (their uncle).
 * Continued as when Jesse's kids are born, again, they look like Joey.
 * When Teri Garr guest-starred on Friends, the producers took advantage of her resemblance to Lisa Kudrow by casting her as Phoebe's birth-mother.
 * Sal Barone, the original actor for D.J. on Roseanne, left the show after the pilot, for various reasons; but what sealed the deal in casting Michael Fishman as his replacement was that he looked just like Roseanne Barr.
