->'''Abed:''' When you guys first came in, we were as wholesome as the family in ''Series/TheBradyBunch''. Now we’re as dysfunctional and incestuous as the cast of ''The Brady Bunch''.
-->-- ''Series/{{Community}}'', "[[Recap/CommunityS1E15RomanticExpressionism Romantic Expressionism]]"

Cast Incest is a variant of RomanceOnTheSet, where two actors from a TV series or film start dating in real world, after they've been playing family members in the show. Or maybe they were cast into a part specifically because they were already dating/married.

Sometimes it can come from a bad ActorAllusion if two people are playing a couple in a production when they had previously played family members or vice versa.

For the far {{squick}}ier inversion, see IncestuousCasting.

[[folder: Film ]]

* ''Film/FerrisBuellersDayOff'': On-screen siblings Matthew Broderick and Jennifer Grey dated after appearing in this film together.
** The actors who played their parents, Cindy Pickett and Lyman Ward, met on the film and were married for several years.
* ''{{Blades of Glory}}'': Creator/WillArnett and Creator/AmyPoehler who play the sibling ice skating duo are married in real life and were well before the film was made. And it's [[BrotherSisterIncest not exactly platonic]] in the film either.
* ''Film/MrsMiniver'': Creator/GreerGarson married Richard Ney, who was her on-screen son.
* ''Film/TheChroniclesOfNarnia''. In the early years, it was actually implied that the actress who played [[GeorgieHenley Lucy Pevensie]], had a PrecociousCrush on her co-star who played ''[[SkandarKeynes her older brother]]'', due to the fact that she constantly mentioned him in the audio commentaries, tried to attract his attention and said how she missed him the most. The movie's producers and executors even named one of the audio commentaries ''Georgie loves Skandar''. Fortunately, they laughed it off, cause she was just a little girl with a crush.
* RobertPattinson, who plays Edward Cullen in ''Literature/{{Twilight}}'', was seen dating his co-star Nikki Reed, who plays Rosalie Hale, his [[NotBloodSiblings adoptive sister]] in the movie. Made even funnier by the fact that, in the book, their characters were supposed to fall for each other but never did.
* Nikki Reed also dated for two years Victor Rasuk who played her onscreen brother in the movie Lords of Dogtown.
* ''Loverboy'' (not the one with Patrick Dempsey): [[FreudWasRight Kevin Bacon plays his real-life wife's father]]. No wonder the [[AntiSue character's]] screwed up.
* ''[[Franchise/EvilDead The Evil Dead]]'': Creator/BruceCampbell revealed in a Q&A session that he lost his virginity to Ellen Sandweiss. [[AManIsNotAVirgin At age 23]].
* A strange ActorAllusion version with Shailene Woodley and Ansel Elgort. In ''{{Divergent}}'' they play siblings Beatrice and Caleb Prior. In ''TheFaultInOurStars'' they play lovers Hazel and Augustus.
* ''Theatre/TheSoundOfMusic'': Charmian Carr, who played Liesl, admitted she had a crush on her onscreen father, Creator/ChristopherPlummer. Plummer would admit the feeling was mutual, but never went beyond flirtation.
* In ''House of D'', a semiautobiographical film written and directed by David Duchovny, the Duchovny character's neglectful, alcoholic, pill-popping ''mother'' was played by his then wife Tea Leoni. Richard Roeper described this as "[[FreudWasRight a bit of casting that would knock Freud of his chair]]"

[[folder: Live Action TV ]]

* ''Series/DoctorWho'': Creator/DavidTennant, the Tenth Doctor, is married to Creator/GeorgiaMoffett who played the eponymous character in "The Doctor's Daughter". Not only that, but Georgia Moffett is the daughter of Creator/PeterDavison, one of Tennant's [[TheNthDoctor predecessors]] in the role. They now have a daughter, so there is now a child out there that has the Doctor as a father and a grandfather. To sum up: [[Creator/PeterDavison A Doctor]][[Creator/GeorgiaMoffett 's daughter]] [[Recap/DoctorWhoNSS4E6TheDoctorsDaughter who played the Doctor's daughter]] [[Creator/DavidTennant and then had the Doctor's daughter.]]
** But they didn't call her [[http://en.wikipedia.org/wiki/Susan_Foreman Susan]].
* ''Series/{{Dexter}}'': Michael C. Hall (Dexter Morgan) and JenniferCarpenter (Debra Morgan) are playing onscreen siblings. For a couple of years they were married in RealLife.
** The CastIncest isn't quite as {{squick}}y as the fact that Debra (quite unknowingly) dated her (adoptive) brother's (biological) brother.
*** Since Dexter and Debra are not biologically-related, this also somewhat mitigates the {{squick}}.
** [[spoiler: The sixth season suggests that Debra has sexual feelings for Dexter.]]
* ''{{Series/Everwood}}'': Emily [=VanCamp=] ("Amy") and Chris Pratt ("Bright") dated in real life while being siblings on the series.
* ''WizardsOfWaverlyPlace'''s actors, SelenaGomez and DavidHenrie, who play brother and sister, were seen, in Puerto Rico, dining at a restaurant known by locals as a "dating hotspot". It doesn't help the fact that they seem to like each other a lot since [[BrotherSisterIncest their own characters]], in the movie, appear to have {{UST}} problems, according to many fans. Selena even said in an interview that she actually had a crush on David when they were younger.
** That was a few years ago, now they recently admitted that they used to casually date, but they don't want to get involved into something serious, due to the fact that, well, they are [[UnfortunateImplications Justin and Alex Russo]] after all.
* Ryo Narushima (formerly Keiko Hayase) and Ryuhei Kobayashi, the actors who played the twin Hoshikawa siblings of Remi and Fumiya in ''Series/ChikyuuSentaiFiveman'', dated each other while filming the series. They were married after the show ended and have since raised three children.
* ''Series/{{Heroes}}'': Heroes co-stars HaydenPanettiere (Claire Bennet) and Milo Ventimiglia (Peter Petrelli) dated while playing an onscreen uncle and niece. They've since broken up, but that hasn't stopped the shippers from [[RelationshipWritingFumble shipping Peter/Claire who are uncle and niece]].
** Or the writers.
* ''TheBradyBunch'': Barry Williams (Greg) went out to dinner once with Florence Henderson, his TV (step) mom, and the media made a bigger deal out of it than it actually was. A full-fledged relationship did not come of it.
** There was a behind-the-scenes special a few years back that revealed that just about everyone ended up hooking up to one extent or another, usually with their counterpart.
* ''Series/DueSouth'': Paul Gross is married in real life to the actress who played his character's mother's young ghost.
** She also played his (off-and-on) lover in ''Slings & Arrows'' a few years down the road. Not only that, but much of this series, which is an employment comedy about theatre, revolves around the (dysfunctional) familyishness of said theatre.
* ''Series/{{Lost}}'': Michael Emerson is married to the woman who plays Ben's mother. Somewhat offset by the fact they never share screen-time with each other.
** Ian Somerhalder (Boone) and Maggie Grace (Shannon) briefly dated.
*** This also happened to be canon incest for the characters. I mean, they're step-siblings, but they call each other brother/sister. It's confusing and awkward.
* ''Series/BrothersAndSisters'' had to do a serious retcon due to the sexual chemistry between the actors playing half-siblings Rebecca and Justin. Supposedly these two dated early on in the run of the show.
** Which is especially funny as the actress playing Rebecca, Emily [=VanCamp=], is also mentioned in the ''Everwood'' entry above
** David Annable, who played Justin, also allegedly dated Sally Fields, his onscreen mother.
* On ''{{Roswell}}'' the actors who played Max and Isabel (siblings) were dating in real life.
* David Cassidy and Susan Dey, who played siblings on ''{{The Partridge Family}}'', slept together shortly after the series ended. She had a huge crush on him; he claimed he loved her like a sister, but made an effort anyway. It didn't work out.
* Bruce Boxleitner married Kathryn Holcomb, his TV sister from ''Film/HowTheWestWasWon''.
* Early on in the run of ''NipTuck'' onscreen mother and son Joely Richardson (Julia) and John Hensley (Matt) were dating in real life.
* Lauren Graham and Peter Krause who play siblings on ''Series/{{Parenthood}}'' are currently dating, which is naturally becoming a RunningGag for Lauren on media tours to joke about dating her "brother".
* In ''Series/StrangersWithCandy'', Creator/StephenColbert's wife briefly appears as his character's mother in a flashback. To make things interesting, in TheMovie, she's his character's ''wife'' (who was played by a different actress in the series).
* In the 80s mini-series ''North and South'' (the Second Book), Kirstie Alley and her then-husband Parker Stevenson played siblings Virgilia and Billy Hazard, respectively.
* John Travolta became romantically involved with Diana Hyland after she played his mother in ''TheBoyInThePlasticBubble''
* ''Series/BlueBloods'': Alluded to in an interview, where Tom Selleck had to remind himself not to have any chemistry with his on-screen adult daughter.
* Real-life married couple David and Tamela Mann play father and daughter on TylerPerry's ''Meet the Browns''.
* ''Series/{{Degrassi}}'': Ray Ablack briefly dated Melinda Shankar, who plays his younger sister.
* Series/MrsBrownsBoys... Let's just copy/paste from wikipedia on this one. "Many of the main cast are played by O'Carroll's real-life family. Cathy Brown is played by his wife, Jennifer Gibney; Winnie [=McGoogan=] by his sister; Maria Nicholson by his daughter and her real-life husband plays her brother-in-law Trevor; Buster Brady by O'Carroll's son and Betty Brown by his daughter-in-law. The character of Dermot, is played by an actor who is a very close family friend of O'Caroll's."

[[folder: Professional Wrestling ]]

* Wrestling/KenShamrock dated Alicia Webb, who portrayed his {{Kayfabe}} sister 'Ryan Shamrock'. There was even a plan to do an "incest" storyline with them, but this was dropped once Webb was released by Wrestling/{{WWE}}.
* Best known for her work in Wrestling/{{ECW}} from 1995-1998 as Wrestling/{{Beulah McGillicutty}}, Trisa Hayes had a short-lived role in Stampede Wrestling in the mid-1980s as Wrestling/BrianPillman's "sister" Theresa, as she and Pillman had been dating in RealLife at the time.

[[folder: Theater ]]

* Rebecca Caine played Cosette in the original, 1985 London production of ''Theatre/LesMiserables'', opposite Colm Wilkinson as Jean Valjean, Cosette's [[ParentalSubstitute father-substitute]]. Then, she was cast as Christine in the original Canadian company of ''ThePhantomOfTheOpera'' - opposite Colm Wilkinson as the Phantom.
* George Hearn (The Broadway replacement for Len Cariou as Sweeney Todd) and Betsey Joslyn (replacement for Johanna, Sweeney's daughter) were married in real life before the production. This can be seen on the tour DVD.

[[folder: Webcomics ]]

* ''KevinAndKell'' also gives an InUniverse example: the recent arc is of Rudy's high school putting on a production of ''West Habitat Story'', that universe's version of ''Theatre/WestSideStory''. His girlfriend Fiona is cast as Maria. Rudy himself? Cast as Maria's brother Bernardo. As they put it, "awkward...".
** At least until Rudy forgot it was a play and slugged Edgar (Tony) for kissing Fiona. The director's response was to promptly recast him as Chino, Maria's would-be suitor. But for about a week it still counted!

* ''MeAndMyDick'' can turn very gross very fast if you can not stop thinking about the last musical you saw the OfficialCouple in, ''AVeryPotterMusical'', where they played siblings Ron and Ginny Weasley.

[[folder: Western Animation ]]

* A flashback in ''WesternAnimation/AxeCop'' has the titular character's mother voiced by Megan Mullally (who voices most of the female characters in the show). She's the wife of Nick Offerman, who plays Axe Cop.
