NCIS/Trivia

"Fornell: I was on the team that nailed Bundy, Gibbs. And I'm familiar with sick, charming bastards. Gibbs: That's probably why we get along so well."
 * Actor Allusion:
 * In one episode, Gibbs is asked what Ducky looked like when he was younger. He responds, "Illya Kuryakin", who was David McCallum's character in The Man from U.N.C.L.E. 40 years earlier.
 * Gibbs once asked Tony for help with the crossword puzzle clue "TV Drama" and Tony answers "St. Elsewhere", which Mark Harmon appeared on.
 * Tony once says "I've got a better chance of hooking up with Jessica Alba than these guys do of infiltrating Sea Lift." Michael Weatherly was engaged to Jessica Alba for a time. He also starred with her in Dark Angel, where they kept trying to hook up.
 * In the episode "Obsession" (Season 7 Episode 21), Tony obsesses over a journalist who embodies all what he finds attractive in a woman, and who is missing. When calling her at her cell phone, he says: "It would seem strange, but I feel like I know you." It's not so strange, though: the journalist is played by Ashley Scott, who also played underground operative and potential secondary love interest Asha Barlow in Dark Angel.
 * In the Season 4 Halloween episode "Witch Hunt", Abby, in her Marilyn Monroe Halloween Costume, calls Gibbs "Mr. President" in a reference to John F. Kennedy. However, Mark Harmon also played the US President in the 2004 film, Chasing Liberty.
 * Harmon's turn as serial killer Ted Bundy (in the TV movie The Deliberate Stranger) is referenced by Fornell in the episode "Smoked" (Season 4 Episode 10).

"Tony: Damn, I can't believe this... Mick and Jessica broke up, I'm always the last to know."
 * In the Season Eight double episode "Enemies Foreign/Domestic", Tony makes a reference to The West Wing by calling McGee "McBartlet". Both Mark Harmon and Michael O'Neill (who guest stars in these episodes) played secret service agents on the show.
 * A combination of Actor Allusion and Shout-Out: Tony (Mike Weatherly)'s father is played by Robert Wagner. Weatherly met NCIS producer Donald Bellisario while Weatherly was filming The Mystery of Natalie Wood, in which he played Wood's husband... Robert Wagner.
 * In the episode "Light Sleeper" while on stake-out Tony is reading an entertainment magazine.


 * This is just after Michael Weatherly and Jessica Alba broke up.


 * A retroactive one: Early in Season 7, a Metro detective who annoys Gibbs is described as having "tugged on Superman's cape".
 * In the Season 9 episode "Newborn King", Jimmy Palmer, when explaining that his future Father-in-Law, Ed Slater, is visiting the NCIS building, he mentions that the first time he learned that Palmer was marrying his daughter, "[Ed Slater] laughed, and then he cried from laughing too hard". Ed Slater is played by Larry Miller, who himself used the phrase "I laughed, I cried" during his first Is This Thing Still On? moment as Principal Jindrake in the movie Max Keeble's Big Move.
 * In Season Five's "Recoil", Nick Chinlund guest-starred as a detective hunting a serial killer who murdered women and cut off their fingers. Sixteen years earlier, he played Donnie Pfaster on The X-Files — as a serial killer who murdered women and kept their fingers.
 * Ziva's codename in "Blowback" is 'Dark Angel'.
 * Season 9 introduces Dr. Samantha Ryan (played by Jamie Lee Curtis) as a psychologist and love interest for Gibbs. This is a reference to Freaky Friday in which she played a psychologist, frustrated with the fact that her unruly teenage daughter refuses to accept her fiance—named Ryan, played by Mark Harmon.
 * In one episode, Gibbs shows off a pretty good arm when it comes to throwing a football; Mark Harmon played quarterback at UCLA.
 * Backed by the Pentagon: The Navy and USMC support the show because malfeasance (regardless of whether it is done by service members or otherwise) is always brought to justice. In "Child's Play" (Season 7 Episode 9), NCIS Agent Ray, who lost in checkers to the child prodigy, was played by Ray Mabus, the current Secretary of the Navy.
 * Beam Me Up, Scotty: Abby is repeatedly misquoted as having screamed "Stop looking up my skirt!" in "Bloodbath". What she actually says is "And don't look up my skirt!"
 * Cast the Expert:
 * Pauley Perrette studied sociology and criminal science before becoming an actress and playing forensic specialist Abby Sciuto.
 * An interesting inversion with David McCallum, who knew nothing of pathology when he was cast as Ducky, but developed such an expertise over the years in his studies for the role to make Ducky as spot on to real coroners that the showrunners were considering paying him a consulting fee.
 * The Character Died with Him: With Ralph Waite dying, Jackson Gibbs died as well. It happened in "Honor Thy Father".
 * Colbert Bump: Prior to the series airing, real NCIS agents referred to themselves as the Rodney Dangerfields of law enforcement because the agency was so obscure they couldn't get any respect. Once the show became a hit, people knew what the agency did and news reports stopped saying "Naval investigators" and actually referring to the agency as "NCIS" or "Naval Criminal Investigative Service".
 * Defictionalization: Theakston's Christmas Ale. Theakston was already a real brewery, but they didn't make a specific Christmas beer - until NCIS fans started inquiring about it.
 * Directed by Cast Member: Michael Weatherly directed Season Eight episode "One Last Score".
 * Dye Hard: Pauley Perrette is a natural blonde but dyes her hair black to play Abby (occasionally using black powder to hide her roots for when she's too tired to dye them). The cumulative effects of dyeing her hair for so long caused her to have a severe allergic reaction that made her face swell up like a balloon. The left side of her face is noticeably puffy in the early episodes of Season 12.
 * Edited for Syndication: At least in daytime UK screenings, for gore and violence rather than for timing.
 * Fake Nationality:
 * Coincidentally, the in-series siblings Ziva and Ari. The Israeli Mossad agent Ziva is played by Chilean actress Cote de Pablo, and the Israeli/Palestinian double agent Ari is played by German actor Rudolf Martin.
 * Director Thomas Morrow is portrayed by Alan Dale, who is from New Zealand.
 * Fandom Nod: In the Season 9 episode "Life Before His Eyes", Gibbs imagines what his life would be like if several things had gone differently. In his alternate timeline, Ziva never came to join NCIS and instead gets arrested for terrorism. Tony is the one to interrogate her, and "guesses" her name wrong several times. One of the names he calls her is "Tiva", which is the online Portmanteau Couple Name given to the Tony/Ziva ship.
 * Harpo Does Something Funny: Gibbs simply glaring as other characters have one-sided conversations wasn't something the writers came up with. It was Mark Harmon choosing not to say his lines at all and simply use facial expressions to react to information being given to Gibbs. It quickly became a hallmark of the show and certainly made watching Info Dump scenes a lot more enjoyable.
 * Hey, It's That Guy!: The main cast have appeared in a lot of other shows. Mark Harmon, Rocky Carroll and Lauren Holly all costarred on Chicago Hope. Carroll had his own sitcom and was the voice of Derek Maza/Talon on Gargoyles. Holly had starring roles in Dumb and Dumber and Picket Fences. Sean Murray was on Hocus Pocus and JAG; he played two different characters in JAG so if you count it as being in the same verse as NCIS it means he's played 3 different characters in the same universe. Michael Weatherly was on Dark Angel. More recently, the actress who played Agent Lee, Liza Lapira, has turned up in Dollhouse and Dexter. Ducky co-starred in The Man from U.N.C.L.E. as Illya Kuryakin (or as Eric Ashley-Pitt from The Great Escape). NCIS's pilot episode can count as a Mythology Gag of sorts, since Ducky at times appears to be the team leader instead of Gibbs, mirroring his prominent role in UNCLE. See also Actor Allusion. Also, although not likely to be brought up in an American show, McCallum was the Steel half of Sapphire and Steel.
 * Stargate SG-1 fans will wonder about how the SGC intends to get Jonas Quinn off for serial murder in "Skeletons". They might be further confused by Martouf being a dirty Metro cop in "Lost And Found". Master Bra'tac apparently has a double life as elusive ultra-forger Khamal Khakani. Colonel Makepeace appears as an ex-Army colonel running a mercenary band that's hunting Mike Franks' daughter-in-law in a season 7 episode. Valla murders a man who has been killing off her dealers in season 7 episode "Borderland". The late Don S. Davis appeared as a government official in the second season and contributed to one of McGee's most awesome moments. And Jack O'Neill's clone was apparently adopted by a Marine and who was forced to hold a classroom hostage by Mexican drug runners. Stargate Atlantis fans will notice that Michael kidnapped Director Sheppard, and Elizabeth Weir is an overworked ME in "Identity Crisis" and recurs as Ducky's temporary replacement. For the Stargate Universe fans there's the deceased Gloria Rush as the now deceased Lara Macy and Tamara Johansen as Dana Arnett from the Season 5 episode "Leap of Faith".
 * One episode had a random teenager played by Zac Efron, in all his feather-headed glory.
 * Zain Nadir was a Mossad agent who Ziva slept with.
 * Casey Novak as Gibbs' Distaff Counterpart in "Jurisdiction".
 * Castiel accidentally stole a car with an injured, kidnapped woman in it. After he recovered her he . Kevin Ryan.
 * Is that Lacey Burrows who's the concerned housewife ?
 * "Caged" even features a minor appearance from The Man Your Man Could Smell Like.
 * Yinsen loses another family member, but doesn't go to see them this time around.
 * Gibbs made out (and more) with Voyager's Borg Queen!
 * Anthony DiNozzo Senior regretfully informs Dr. Evil that they have no sharks.
 * Season 8 had a guest-appears of Alimi Ballard as Special Agent Levin, that is, David from Numb3rs.
 * The teenager who holds his class hostage with a bomb in Season 3 is Mike Newton.
 * The guy at the toy shop that likes CSI in Season 1 Episode 13 is Hodgins.
 * In Memoriam: The Season 11 finale "Honor Thy Father", in which Jackson Gibbs dies off-camera, is dedicated to his actor, Ralph Waite, who died three months before the episode aired.
 * The German dub paid tribute to Ducky's previous German voice actor in early February 2014.
 * The Pete Best: Robyn Lively played Special Agent Vivian Blackadder in the two-part JAG Poorly-Disguised Pilot. Donald Bellisario reportedly said she was "too soft" for the new show, and she was replaced by Sasha Alexander's Caitlin Todd for the series proper.
 * Real Life Relative:
 * Sean Murray, who plays McGee, is the real-life stepson of the show's creator Donald Bellisario.
 * McGee's sister is played by his real-life stepsister.
 * In one Season 9 episode, Abby shows the others a locket containing a picture of her mother. The picture is of Pauley Perrette's real-life (deceased) mother, Donna. The lock of Abby's mother's hair inside the locket was also that of Pauley's mother.
 * The young Gibbs is played by Mark Harmon's son Sean.
 * Sleeper Hit: NCIS is one of the rare examples of a show that's steadily increased its viewing audience as it's gone on. Try to think of another show that hit a series-high in viewers in its eighth season.
 * What Could Have Been:
 * Production notes from the show say that the plan was to develop a romantic relationship between Kate and Tony. Sasha Alexander's decision to leave the show after two seasons prevented that potential arc from happening. It's touched upon in the show's 200th episode where, in an alternate reality, Tony and Kate marry and start a family while Kate continues to be exasperated at Tony.
 * Vivian Blackadder as a member of the NCIS team in the pilot, before she was replaced by Kate.
