When two or more characters in a show are played by actors who have some form of real-life relationship, be it familial or romantic, off-screen. The relationship is likely to be replicated on-screen: the actual family resemblance between real-life blood relatives can go a long way toward convincing the audience that their characters are family, and love scenes may well be more convincing if the participants are in a real-life relationship. On the other hand, there's no guarantee that real-life couples will necessarily have much on-screen chemistry.

Can lead to some very interesting scenarios, including {{Actor Allusion}}s, or may lead to more RealitySubtext issues than the production was actually looking for. (In films, this element can often be played up by the promotional machine.) For a more Squick version there is CastIncest, where the actors of characters who are blood related go out in real life. The even ''squickier'' inversion is IncestuousCasting, where actors who play romantic partners on screen are blood related in real life.

It is also not unheard for a couple to be on opposite sides of an on-screen divide, making for some interesting FoeYay scenes.

Compare IWantYouToMeetAnOldFriendOfMine, CoupleBomb and ActorAllusion. For cases where actors start a real-life relationship after being cast as characters with an on-screen relationship, see RomanceOnTheSet.

[[folder:Anime & Manga]]
* Occasionally happens in FUNimation dubs. Jessica Dismuke played Yukina in ''Manga/YuYuHakusho'', while her brother Aaron played Shura, although the two never had a scene together and their cousin Justin Cook played Yusuke. Linda Young (Genkai) and John Burgmeier (Kurama) are also mother and son.
** Aaron also voiced a young Yusuke for a brief scene that showed him as a kid.
* Chris and Greg Ayres. ''Anime/SpeedGrapher'', ''LightNovel/FullMetalPanic'', ''Manga/InitialD'', ''Anime/DragonBallKai'', ''VideoGame/SengokuBasara''...
* In the English dub of ''WickedCity'', Gregory Snegoff and Alexandra Kenworthy, who are son and mother, play Taki and Mackie who are lovers.
* Creator/YujiUeda and Creator/OmiMinami who are married in RealLife are cast in ''Anime/MartianSuccessorNadesico'' as Akito Tenkawa and Ruri Hoshino. Thankfully however, they're not a couple seeing as Ruri is a LittleMissSnarker and Akito's pretty much in his late teens.
** This gets a bit more awkward in Sensei no Ojikan/''DokiDokiSchoolHours'' where they play teacher and student.
* The Disney's English Dub of ''Anime/MyNeighborTotoro'' have Creator/DakotaFanning and Creator/ElleFanning play the Kusakabe sisters.
* Voice actors Creator/AmandaWinnLee and Jason C. Lee are married, which makes their roles as the Bonnie & Clyde-esque [[HeroicComedicSociopath protagonists]] of ''DeadLeaves'' amusing and Shigeru Aoba (Jason)'s [[spoiler: tanging]] scene at [[spoiler: the hands of Rei (Amanda)]] in ''TheEndOfEvangelion'' hilarious.
* TravisWillingham (Roy Mustang in ''Manga/FullmetalAlchemist'') and LauraBailey (Lust) are married, which renders the violent confrontation between Mustang and Lust in episode 19 of ''Brotherhood'' HilariousInHindsight. While they weren't married yet at the time, they were in a relationship, and they find this just as funny as the rest of us do.
* Japanese voice actors Creator/KenichiSuzumura and Creator/MaayaSakamoto are married, which makes their playing Shinn Asuka and Lunamaria Hawke in ''Anime/MobileSuitGundamSeedDestiny'' all the more interesting retroactively, considering the two characters end up in a relationship. They're also the voices of Haruhi and Hikaru from ''Manga/OuranHighSchoolHostClub,'' along with Shiki and Mikiya in ''LightNovel/KaraNoKyoukai''.

[[folder:Films -- Live-Action]]
* In The Guys Creator/SigourneyWeaver's daughter is played by her real life daughter Charlotte Simpson.
* SylvesterStallone's son Sage played Rocky Balboa's son in 1990's ''Film/RockyV'', but turned down the role for the 2006 sequel, ''RockyBalboa'', with Milo Ventimiglia [[TheOtherDarrin taking over]] the role.
** And Sly's brother Frank Stallone appeared in ''RockyII'' and ''RockyIII''.
* WillSmith and his son, Jaden Christopher Syre Smith, played father and son in the 2006 film ''Film/ThePursuitOfHappyness'', and in the 2013 ''AfterEarth''.
* Will Smith and his daughter, Willow Smith, played father and daughter in the 2007 film ''Film/IAmLegend''. Apparently Smith is a fair dad and wanted to give both his kids a movie.
* Will Smith's two sons made cameo appearance in ''Film/MenInBlack 2'' as two boys being neuralyzed in a climatic flying car chase scene.
* All of the (many) movies that have starred real-life husband and wife Richard Benjamin and Paula Prentiss.
* Both {{Malcolm McDowell}} and his nephew [[DeepSpaceNine Alexander Siddig]] appear in Neil Marshall's 2009 film {{Doomsday}}.
* Freddie Prinze Jr. and Sarah Michelle Gellar were married during the production of the two ''ScoobyDoo'' films.
* In ''{{Carrie}}'', Priscilla Pointer plays her daughter Amy Irving (Sue Snell)'s character's mother, something which Creator/BrianDePalma seems to have done in ''Sisters'', too, with Jennifer Salt's mother playing her mother.
* In ''Film/ManosTheHandsOfFate'', the actress who played the daughter, Debbie, Jackie Neyman, was actually the real-life daughter of the actor who played The Master, Tom Neyman. [[IncestIsRelative Well, that just puts a whole new spin on the ending, now doesn't it?]]
* ''Film/TheChroniclesOfNarnia''. Grown-up Lucy Pevensie at the end of the movie was actually played by Creator/GeorgieHenley's older sister, Rachael Henley.
* Luke and Owen Wilson, brothers in real life, were together in ''TheRoyalTenenbaums'', but not as brothers (Luke played Ritchie Tenenbaum, while Owen played Eli, a friend of the Tenenbaum kids). They were also in Disney's ''AroundTheWorldInEightyDays'' -- as the Wright Brothers.
** Luke also appears with his other brother, Andrew, in ''Film/{{Idiocracy}}''. Andrew is Beef Supreme, one of the "corrections personnel" trying to kill Joe (Luke) in "Rehabilitation".
* ''Film/LaraCroftTombRaider'': Richard Croft was played by Creator/JonVoight, AngelinaJolie's father. However, Jolie and Voight weren't getting along. Clever editing and writing allowed for them both to appear in the movie without ever being on the same set at the same time.
* In the movie ''Eegah'', writer/director Arch Hall Sr. cast his son Arch Hall Jr. as the boyfriend of his character's daughter. There were probably some awkward moments on that set.
** Not as much as the second ''{{Underworld}}'', where Scott Speedman even joked that he didn't know how to ask the director "how do I make love to your wife?".
* In ''Film/KickboxingAcademy'', characters played by a real-life brother and sister ([[Series/PowerRangersInSpace Christopher Khayman Lee]] and [[GreysAnatomy Chyler Leigh]], despite the spelling) kiss. Awkwardness ''not'' avoided for viewers who know about this. This would not be the siblings' only onscreen kiss, leading to some speculations about those two....
* MartinSheen and his sons Emilio Estevez and Creator/CharlieSheen often appear in film together, though not always as relatives.
** In ''YoungGuns'', Emilio's character is even more or less responsible for the death of Charlie's.
** A very memorable scene from ''HotShots 2: Part Deux'' featured Charlie's character writing a journal as a nod to his role in ''{{Platoon}}'', which then fades into Martin Sheen parodying a monologue from ''Film/ApocalypseNow''. The two then stand up and give each other the thumbs up as their boats pass, both saying "I loved you in ''WallStreet''" (another film they both starred in, where they played father and son).
** Then there was the film ''Men At Work'', written by and starring Charlie Sheen and Emilio Estevez. They're not related in the film, however.
** Estevez and Sheen also share screentime together in ''Film/LoadedWeapon1''.
** Another movie Martin and Emilio star together as father and son is ''Film/TheWay''.
** Emilio and Martin also appeared in Charlie's sitcom ''TwoAndAHalfMen''.
* Then-couple Creator/TomCruise and Creator/NicoleKidman in ''Film/EyesWideShut''. Apparently director Creator/StanleyKubrick wanted a real couple for the scenes together. (He had thought about a different famous actor couple before; Alec Baldwin and Kim Basinger.) We all know how ''that'' ended up.
** Tom and Nicole also starred in ''Film/DaysOfThunder'' and ''Film/FarAndAway'' as a couple.
* In the ''lucha'' movie ''La Venganza de la Momia'' (The Vengeance of the Mummy), ElSanto adopts a young boy after the monster of the title kills the boy's grandfather. The boy is played by one of Santo's sons.
* Near the end of the last ''Film/TheLordOfTheRings'' movie, there's a scene with Sam, Rosie, and their two children. The children seen are Sean Astin's (Sam) daughter and Sarah [=McLeod=]'s (Rosie) baby daughter.
* ''Film/DonnieDarko'', where the sister of the eponymous character (played by Creator/JakeGyllenhaal) is played by Creator/MaggieGyllenhaal, Jake's sister.
** Jake also wound up co-starring with his eventual brother-in-law Peter Sarsgaard in ''{{Jarhead}}''.
* There is also Walter Hill's western ''TheLongRiders'', which starred James and Stacy Keach as Jesse and Franck James, David, Keith and Robert Carradine as Cole, Jim and Bob Younger, Dennis and Randy Quaid as Ed and Clell Miller, and Christopher and Nicholas Guest as Charley and Robert Ford.
* Siblings [[Creator/JohnCusack John]] and Joan Cusack frequently appear together. In ''Say Anything...'' and ''Martian Child'' they played siblings. In ''HighFidelity'' they play siblings yet again, and their real life mother appears as the mother of their characters.
* Jerry Stiller and his son Creator/BenStiller:
** ''{{Zoolander}}'' is written by, directed by, and stars Creator/BenStiller. No wonder, then, that his father, Jerry Stiller, also gets a prominent role.
*** His mother, Anne Meara, also features in a cameo. Not to mention his wife, Christine Taylor, playing his love interest.
** The two play opponents of each other in ''{{Dodgeball}}: A True Underdog Story''.
** Also both star together in {{Heavyweights}} and TheHeartbreakKid.
* In ''Film/RunLolaRun'', the blind woman who gives Manny a phone card is his mother in real life.
* In the comedy ''Blades of Glory'', Creator/WillArnett and Creator/AmyPoehler (married in real life) play a pairs team of brother and sister. Towards the end of the movie, their real-life relationship is replicated, with disturbing results.
* Real-life mother and daughter DianeLadd and Creator/LauraDern have played mother and daughter in at least six movies (cf ThoseTwoActors: ''Rambling Rose'', ''White Lightning'', ''WildAtHeart'', ''Citizen Ruth'', ''Daddy And Them'' and ''InlandEmpire''.
* The Willis family:
** In ''Film/{{Striptease}}'', mother and daughter Erin Grant and Angela Grant are played by real-life mother and daughter Creator/DemiMoore and Rumer Willis (her dad is Creator/BruceWillis).
** In the movie MortalThoughts, Creator/BruceWillis played a vicious wife-beater who constantly sexually harassed his wife's best friend, played by his then-wife Creator/DemiMoore. Made all the more complicated [[spoiler: when the two filmed a violent attempted rape scene.]]
** Bruce and Demi also voice a criminal couple in ''[[WesternAnimation/BeavisAndButtheadDoAmerica Beavis and Butt-Head Do America]]''. Bruce's character starts the plot by hiring assassins to kill Demi's character.
** Bruce Willis and Rumer Willis can be seen together in ''Film/{{Hostage}}''.
* In ''Grizzly Mountain'', Dan Haggerty stars in the show - as do his two children, Dylan Haggerty and Megan Haggerty. Dylan is one of the protagonists, while Megan is the ''other'' sister. They have no apparent relationship to Dan Haggerty's character. All three siblings [[TheDanza also share names with their actor counterparts]].
* In the first scene of ''Film/JayAndSilentBobStrikeBack'' where we see the title characters as babies, Silent Bob is played by Creator/KevinSmith's daughter. Smith's wife also appears as one of the villainous jewel thieves, who noticeably takes no part in the gang's big scene as she's getting the van ready. Smith says on the DVDCommentary, "A better husband probably would have given her more to do." He does make an ActorAllusion out of it though. She comments to the others, "The fat one is creeping me out."
** She also appears as a receptionist in ''Film/JerseyGirl'' and is finally given a more important role in ''Film/ClerksII'' as Dante's fiancé. Smith's daughter also appears in ''Film/ClerksII'' as the little girl who waves at Dante from her dining room window before the donkey show.
** KevinSmith's real-life mother plays the "Milkmaid" in ''Film/{{Clerks}}''; she reprises the role in ''Film/ClerksII''.
* KennethBranagh and Creator/EmmaThompson, then husband and wife, played Benedick and Beatrice in Branagh's ''MuchAdoAboutNothing''. Now a FunnyAneurysmMoment.
** They also played Roman and Margaret in ''DeadAgain'' and Henry V and Katherine in ''Henry V''. And [[http://www.imdb.com/search/title?roles=nm0000110%2Cnm0000668 a couple of other things.]]
* No one knew that porn stars Amber Lynn and Buck Adams were brother and sister until they were cast in the same film and were scheduled to have sex with each other. They put a stop to ''that'' pretty damned quick by revealing their relationship to one another.
* During their marriage, Creator/ElizabethTaylor and Richard Burton appeared in several films together; the most famous is ''WhosAfraidOfVirginiaWoolf''. Not that there's any irony in that.
* Paul Newman and his wife Joanne Woodward appeared in ten films together.
* Creator/HenryFonda and his daughter [[Creator/JaneFonda Jane]] played father and daughter in ''Theatre/OnGoldenPond''.
* Wah and Qiu Yuen trained under the same master at the China Drama Academy. They've appeared in quite a few martial arts films as a couple, most notably ''Film/KungFuHustle.''
* Siblings Spencer and Creator/AbigailBreslin played siblings in ''Raising Helen''.
* Creator/JuddApatow often casts his wife and daughters in his films, such as ''KnockedUp'' and ''FunnyPeople''. His justification for using his own kids is that he doesn't like child actors and would rather not have to work with them.
* ''Series/{{Wings}}'' is not the only place where Amy Yasbeck and John Ritter have been on screen together. They also appear in both ''Film/ProblemChild'' movies, though Yasbeck inexplicably [[YouLookFamiliar plays two different characters]].
** They were also on an episode of ''TheCosbyShow'' as an expecting couple whose baby is being delivered by Dr. Huxtable.
*** Though, strangely enough, this was years and years before they were even dating.
* ''The Great Buck Howard'' stars Colin Hanks; his more famous dad [[Creator/TomHanks Tom]] shows up briefly as his character's father.
* Denis Lawson, who played the MauveShirt pilot (and very successful AscendedExtra in [[XWingSeries the]] [[Franchise/StarWarsExpandedUniverse EU]]) Wedge Antilles in the Star Wars OT, is the uncle of EwanMcGregor, who played the young Obi-Wan in the prequel trilogy. Apparently Denis told his nephew not to take this gig.
** Lawson was also offered the chance to play a walk-on role in ''RevengeOfTheSith'' as Captain Antilles - the pilot who Vader strangles in ''ANewHope''. Alas, he didn't take it.
* Creator/MonicaBellucci and Vincent Cassel are married and have appeared as a couple in ''L'Appartement'', ''Dobermann'' and ''Film/{{Irreversible}}''.
* Father and daughter Ryan and Tatum O'Neal played two grifters (who are implied to be father and daughter) in ''Film/PaperMoon''.
* In the film version of ''DannyTheChampionOfTheWorld'', Creator/JeremyIrons played Danny's father and his son Samuel Irons played Danny. Additionally, Jeremy Irons' father-in-law (Samuel's grandfather) Cyril Cusack played Doc Spencer.
** The photograph of Danny's late mother was also in fact a photograph of Samuel Irons' actual mother (Jeremy Irons' wife, and Cyril Cusack's daughter, actress Sinéad Cusack).
* In the 2003 film, ''It Runs in the Family'', Creator/KirkDouglas, his son, [[Creator/MichaelDouglas Michael]] and Michael's son, Cameron played three generations of a family. Michael's mother is played by his real-life mother, Kirk's former wife, Diana Dill.
** Kirk also appeared with his son Eric Douglas in movies like ''A Gunfight''.

* In ''Film/KissKissBangBang'', Robert Downey Jr.'s son Indio plays RDJ's character as a young child.
* John Mills and his daughter Haley Mills both starred in the movie ''Film/TigerBay'', he playing a police detective and she the lone witness to a murder he is investigating. The two made other movies together as well.
** In ''The Family Way'', they play a father- and daughter-''in-law''.
* Then-couple Creator/JeffGoldblum and Geena Davis costarred in ''Film/TheFly1986'', ''Transylvania 6-5000'' and ''Film/EarthGirlsAreEasy''.
* In the film ''Miracle'', USA hockey player Buzz Schneider was played by his son Billy. [[http://www.chasingthefrog.com/reelfaces/miracle.php Proof.]]
* Creator/KurtRussell and family:
** Real-life couple Creator/KurtRussell and Goldie Hawn appear together as a couple in ''Film/{{Overboard}}''.
** Russell's first wife, Season Hubley, makes an appearance in ''Film/EscapeFromNewYork'', and his son (with Goldie Hawn), Wyatt, has cameos in both ''Film/EscapeFromLA'' and ''Film/{{Soldier}}''.
** Father and son Bing and Creator/KurtRussell play father and son in ''Elvis'' (1979). Oddly enough, Kurt's first wife Season Hubley plays Priscilla Presley in this one.
* Real life husband and wife Hume Cronyn and Jessica Tandy as Joe and Alma Finley in ''Film/{{Cocoon}}''.
* Janet Leigh and her daughter JamieLeeCurtis in ''Film/TheFog''.
** Janet Leigh had a cameo appearance in ''Film/HalloweenH20TwentyYearsLater''.

** In the epilogue of the eighth movie, Draco Malfoy's future wife is played by Jade Olivia, Tom Felton's girlfriend.
** Anna Friel apparently really wanted to play Nymphadora Tonks so that she could act alongside David Thewlis, her real-life partner. The role went to Natalia Tena.
* In the film ''Film/BarneysVersion'', DustinHoffman's son Jake plays his grandson.
* In ''Film/DaddysLittleGirls'', the main character's three daughters are played by sisters China, Lauryn and Sierra [=McClain=], and their names in the movie are China, Lauryn and Sierra.
* In ''Film/EvesBayou'', Jurnee Smollett(Eve)'s real life brother Jake plays Eve's younger brother Poe.
* In ''Film/{{Bridesmaids}}'', Melissa [=McCarthy's=] husband Ben Falcone has a small role as a man her character (Megan) hits on [[spoiler:and later hooks up with.]]
* ''Film/{{Gigli}}'' was centered on this. As a vehicle for Ben Affleck and Jennifer Lopez's relationship, it died along with public interest over their coupling, along with KevinSmith's ''Film/JerseyGirl'' which starred Affleck and had Lopez in a smaller role.
* While filming ''Film/Terminator2JudgmentDay'', James Cameron [[MakingUseOfTheTwin took advantage of the fact that Linda Hamilton has an identical twin sister]] in order to save on his special effects budget. In three scenes that required two "Sarah Connors" to be on screen at the same time (the playground scene where Conner is trying to warn everyone about the oncoming nuclear war, the CPU reprogramming scene, and the scene where the T-1000 had taken Sarah's form), Cameron used Hamilton's sister, [[http://terminator.wikia.com/wiki/Leslie_Hamilton_Gearren Leslie Hamilton Gearren]], as a double rather than using CGI to achieve the same effect. In addition, the toddler in the nightmare sequence is Hamilton's actual son.
* In the Soviet film ''[[MoscowCassiopeia Teens in the Universe]]'', the leader of the HumanAliens and his son Agapit are played by the RealLife father-and-son Igor and Vadim Ledogorov.
* Creator/TimBurton often casts his real life girlfriends (first Lisa Marie and then HelenaBonhamCarter) with the latter getting the more meatier parts than the former as Bonham Carter was already a well-respected Academy Award nominated actress before she and Burton hooked up.
* In Disney's ''Film/HocusPocus'', "[[{{Satan}} the Master]]" and his wife are played by (uncredited) real-life siblings Garry and Penny Marshall.
* In ''Film/TheShawshankRedemption,'' the old photo of Red, at the time of his incerceration, which is shown briefly when Red is up for parole, is not an old photo of MorganFreeman, but rather a photo of Freeman's son.
* The real parents of ''Film/TheGoonies'' were cast as their parents for the final reunion, save for Mikey and Brand's parents being played by established actors.
* In ''Film/{{Aliens}}'', a scene which was cut and later reinstated for the DVD release shows Newt's parents and brother, Timmy. Timmy was played by Carrie Henn's brother Christopher, who had read the part to help Carrie out and was ultimately cast in the small role.
* In ''Film/{{Freaks}}'', the romance between the male and female circus midgets is muted - they were actually brother and sister in RealLife.
* Any MarxBrothers movie is of course an example, as Chico, Harpo, Groucho and Zeppo were brothers in real life. In the movie ''Film/HorseFeathers'', Zeppo actually plays Groucho's ''son''.
* Creator/ClintEastwood and family:
** ''Film/SuddenImpact'', fourth film of the ''DirtyHarry'' franchise, has SondraLocke, who was in a domestic relationship with Creator/ClintEastwood at the time, as the RapeAndRevenge-driven serial killer antagonist, who eventually ends up sleeping with Harry.
** Clint and daughter Alison Eastwood star together in ''Tightrope''.

* ''HellboyIITheGoldenArmy'': Blake Perlman (daughter of Creator/RonPerlman) can be seen as the reporter in the gray sweater interviewing Hellboy outside the auction house.
* Cynthia Caylor, who plays Portia Leech in ''Film/AFishCalledWanda'' is actually Cynthia Cleese, the daughter of JohnCleese, who plays Portia's father Archie.
* In Film/TheMightyDucks movies, Elden Ratliff (Henson) and Garette Ratliff Henson are brothers who play fellow Ducks, Fulton and Guy.
* In ''The Alternate'', starring Eric Roberts and Bryan Genesse, both Roberts' wife Erica and Genesse's wife Brooke appear.
** Eric and his sister [[Creator/JuliaRoberts Julia]] (in her film debut) played siblings in the long-forgotten Western ''Blood Red''.
* Some more obscure movies make family affairs out of the deal.
* Matthew Macfayden and Keeley Hawes, who play Daniel and Jane in the original 2007 version of ''Film/DeathAtAFuneral'', are married in real life.
* In ''Film/TheHobbit'' film trilogy, James Nesbitt plays Bofur, and [[http://middleearthnews.com/2013/09/24/james-nesbitts-girls-to-play-bards-daughters/ his daughters play Bard's daughters]].
* ''Film/TheMatrix'' movies have Creator/LaurenceFishburne playing Morpheus, while his wife Creator/GinaTorres plays Dozer's widow Cas--two characters who, oddly enough, never actually share a scene. In a notable WhatCouldHaveBeen example, Creator/WillSmith was actually the Wachowskis' first choice for the lead role of Neo, but he had to turn down the role because of his commitment to ''Film/TheWildWildWest''; if he'd accepted it, he would have wound up sharing the screen with ''his'' wife, Jada Pinkett Smith, who was cast as Niobe in the sequels.
* [[Creator/KateBeckinsale Kate Beckinsale]]'s daughter Lyly Mo Sheen has portrayed a child version of her (Kate) in the second ''Film/{{Underworld}}'' and ''Film/EverybodysFine''.
[[/folder]]

[[folder:Live-Action TV]]
* [[Series/ThirtyRock 30 Rock]] has Bertram Geiss (Tony Torn) playing a son of Don Geiss (Rip Torn). Tony is Rip's son. Also, actor John Lutz [[NamesTheSame who plays Lutz on the show]] is married to actress Sue Galloway [[NamesTheSame who plays Sue]] [[FunnyLastName LaRoche-Van der Hout]], though they aren't married on-screen and rarely interact directly with each other.
* Emilio Estevez and his daughter also have a brief appearance in an episode of ''Series/TheWestWing'', in "archival video" of a younger Jed Bartlet and daughter Zoe.
** MartinSheen's daughter Renee has a small recurring role as staffer Nancy, who interacts with the President from time to time. When President Bartlet tells Nancy to 'say hello to your mother for me', that's actually a shout-out to his own wife.
* An episode of ''FantasyIsland'' called "What's the Matter With Kids?" features Steve Allen and Jayne Meadows as husband and wife Child Psychologists.
* One ''Series/{{Highlander}}'' episode had an appearance of Adrian Paul's then-wife Melani as an escaped female con hired to seduce Duncan. (She played the character until the plastic surgery, then Alexandra Vandernoot took over)
* Geraint Wyn Davies' real-life son guest starred in one season 3 episode of ''Series/ForeverKnight''.
** Another episode had the then-boyfriend of Catherine Disher, aka Natalie, as a guest star
* Robert Reed's real life daughter appeared in one episode of ''TheBradyBunch''.

* In ''{{Smallville}}'' twins Shawn Ashmore and Aaron Ashmore both played parts--one an early [[MonsterOfTheweek Freak of the Week]] bit part and the other a cast regular good guy--nobody ever notices they look alike.
* On ''Theatre/TheOddCouple'' TV series, Jack Klugman played bitter divorcee Oscar Madison, and his wife, Brett Somers, played Blanche, Oscar's ex-wife. During the series' run, Klugman and Somers ''really did'' separate, though their marriage didn't officially end until Somers died in 2007.
* ''Series/ArrestedDevelopment'': Creator/AmyPoehler played real-life husband Will Arnett's character Gob's [[spoiler: wife]] for a time.
** Also husband and wife duo Ben Stiller and Christine Taylor play Tony Wonder and Sally Sitwell respectively.
* ''Series/{{Friends}}'': ''Creator/JenniferAniston'' and Tate Donovan
** Matthew Perry's father played Joshua's (Tate Donovan's character) father in one episode.
** When Julia Roberts guest starred, her real life sister played her assistant.
*** Roberts guest starred in the first place because she was dating Matthew Perry at the time.
** In one episode Ross's old friend from high school comes to visit. Turns out he is the president (and only current member) of the Anti-Rachel club. He was played by Jennifer Aniston's then real life husband Brad Pitt.
* On ''Series/GilmoreGirls'', the chemistry between Rory and Jess was made a little more obvious due to the fact that Milo Ventimiglia was already Creator/AlexisBledel's real-life boyfriend when he was cast as Jess. In an odd coincidence, they broke up roughly around the same time the episode where Rory and Jess see each other for the final time aired.
* The new ''Series/{{Battlestar Galactica|Reimagined}}'' has four minor characters played by real-life relatives of the main cast. Bodie Olmos ('Hotdog') is the son of Edward James Olmos (Admiral Adama), Lymari Nadal (Giana) is Olmos's wife, Susan Hogan, the wife of Michael Hogan (Saul Tigh) plays the lead judge in Baltar's trial, and Kerry Norton, Jamie Bamber's ('Apollo') wife plays a medic.

** In the episode ''Greetings from Earth'' in the original series, most of the children are played by children of the series creator Glen A. Larson or star Lorne Greene.
* ''[[Series/BabylonFive Babylon 5]]'' had Bruce Boxleitner and Melissa Gilbert, husband and wife, playing husband and wife. As well, a photo from their real wedding is used in the show as one from the characters' wedding. On the show they don't work out.
** Oddly, Melissa Gilbert was TheOtherDarrin in this example. An episode the previous season had featured a different actress as his wife, but she was unavailable for the second appearance.
*** WordOfGod is that Melissa Gilbert took the role for less money than she usually gets, as a favor to her husband.
* ''Series/{{Jeremiah}}'': In the episode ''Moon in Gemini'', cast regular Ingrid Kavelaars' character Erin has a twin sister named Lauren, played by... her real-life twin sister Monique Kavelaars.
* ''Series/TwoOfAKind'', ''Series/SoLittleTime'', ''Series/SisterSister'', ''Series/DoubleTrouble'', and ''Series/SweetValleyHigh'' are all built around twin sisters being played by twin sisters (first two the Olsens, the other three the Mowrys, Sagals, and Daniels respectively).
* Peter [=DeLuise=], a director of ''Series/StargateSG1'', occasionally also made cameo appearances. His brother David played as a love interest to Carter.
** His other brother Michael [=DeLuise=] appeared as "Colonel Danning" in ''Wormhole X-Treme!'' and father Creator/DomDeLuise as Urgo.
** As well as his wife Anne Marie [=DeLuise=] (nee Loder) as Farrell in ''The Other Side'' and Cameron Mitchell's high school sweetheart Amy Vanderburg in ''Bounty''.

** In another episode, Michael played a younger Doug Penhall with Dom Deluise as his father.
* Also on ''Series/StargateSG1'', actress Lexa Doig joined the cast in season 9 as Dr. Carolyn Lam, working alongside husband Michael Shanks, who played Dr. Daniel Jackson.
* Real-life siblings David and Kate Hewlett also play brother and sister onscreen in ''Series/StargateAtlantis'' in the aptly named episode "[=McKay=] and Mrs. Miller". Fans loved her so much that TPTB brought her back for three more episodes.
** This was actually Art Mimicking Life - in "The Siege" [=McKay=] was originally to have been composing the video to his brother. David Hewlett convinced them to shift it to sister, as he had no brothers, but ''did'' have a sister who was an actress, should they ever want to go that route later on in the series...
** Hewlett said in [[http://scifi.about.com/od/stargate/a/SGA_hewlett.htm an interview]] that in their first episode together the director instructed them to act like brother and sister, forgetting that they actually were.
--->"I remember Martin [Gero] actually said to us once, 'Now remember you guys are supposed to be brother and sister.' And we were laughing because we were treating each other so horribly, we could only be brother and sister. ... He was like, 'Remember you're brother and sister,' and we were like, 'Yeah--? Thank you for reminding us?'"
* ''{{Space 1999}}'', starring Martin Landau and his wife Barbara Bain, both also having starred before in the show ''MissionImpossible''.
** And in the ''MissionImpossible'' revival series, Barney's son was played by the actor's son.
* Kelly Ripa and Mark Consuelos, both regulars on ''AllMyChildren'', were married in 1996... and then their characters got married. Given the nature of many soap storylines, this happened often.
* In ''Series/StarTrekVoyager'', "Q2", father and son John and Keegan de Lancie play Q and "Q Junior". Also an instance of PlotRelevantAgeUp-Q Junior is an adolescent, but the last time we saw him, three seasons earlier, he was an infant. Of course, since he's a SufficientlyAdvancedAlien, he can look however he wants.
* Kiefer and Donald Sutherland in ''ATimeToKill''.
** Donald Sutherland was to play the father of his son Kiefer's character, Jack Bauer, on ''[[Series/TwentyFour 24]]'', but was unavailable at the time of filming and was replaced by James Cromwell.
* "Far Beyond The Stars", an {{Elseworld}} episode of ''Series/StarTrekDeepSpaceNine'' in which the regulars were writers for a 1950s science fiction magazine, had Nana (Kira) Visitor and Alexander (Bashir) Siddig, who were married at the time, as a married couple based on C. L. Moore and Creator/HenryKuttner.
* In the ''Series/{{Farscape}}'' trilogy ''Look at the Princess'', the simulations of John Crichton's son and daughter are played by Ben Browder's children.
** Additionally, Ben Browder's wife, Francesca Buller, has played multiple alien characters, notably War Minister Ahkna.
** Browder's children show up again in ''Series/StargateSG1'' as a pair of random kids running past [=SG1=] in a village.
* ''TheSuiteLifeOfZackAndCody'', with the Sprouse brothers Dylan and Cole as the title characters.
** And the same with any other Disney movie or television show with twins. Disney loves twins and uses them as much as possible.
* ''ThirdWatch'': Paramedics Carlos Nieto and Holly Levine dated and got married in the final season. They were played by real life husband and wife Anthony Ruivivar and Yvonne Jung.
* Another extreme example was the two-part episode "Sandkings" in the 90's remake of ''Series/TheOuterLimits''. Beau Bridges played the episode's main character, Dr. Simon Kress, his father Lloyd Bridges played Simon's father, and his son Dylan played Simon's son.
* ''Series/LittleHouseOnThePrairie'' sports a peculiar variation. Melissa Gilbert, playing Laura Ingalls, is of a different family than her real-life brother, Jonathan Gilbert, playing Willie Oleson. In reality, they were both adopted by the same family but are not blood related. It gets even better because Melissa Gilbert's in-show brother, Matthew Laborteaux, is the real-life brother of Patrick Labyorteaux (Matthew dropped the "y" from his surname), playing Matthew's friend on the show, Andrew Garvey, which are also both adopted! To top that, the role of Carrie Ingalls was played by twins Lindsay and Sidney Greenbush. While it's not rare for twins to play the same role, especially as a baby, there was an episode where both of them played side by side, when Carrie's character created an imaginary friend, played by her actual sister! Even more, the twins have a brother which also appeared as a guest star on the show!
* The '80s Disney TV movie ''The Thanksgiving Promise'' features several members of the Bridges family: Beau, Lloyd, Lloyd's wife Dorothy, Beau's other son Jordan, and an uncredited [[JeffBridges Jeff]].
* In one episode of ''TheLastDetective'', Creator/GeorgiaMoffett guest-starred alongside her dad--star Creator/PeterDavison. The production team wanted the former's character to flirt with the latter's. One or both of them deep-sixed ''that'' idea pronto.
* Creator/PeterDavison and Creator/GeorgiaMoffett, real-life father and daughter, played a father and daughter on ''Fear Stress And Anger''.
* (And for the hat-trick) A particularly unusual variant in ''Series/DoctorWho'': in 2008 Creator/GeorgiaMoffett played the daughter of Creator/DavidTennant's (Tenth) [[Series/DoctorWho Doctor]] -- who is a ''regeneration'' of the same character played five "lifetimes" earlier (the Fifth Doctor) by her real-life father Creator/PeterDavison between 1981-84. The pair began dating after meeting on the set and are now married with a daughter.[[labelnote:Meaning, drumroll, please...]]that The Doctor's Daughter, who also played The Doctor's Daughter, is now The Doctor's Wife and has had The Doctor's Daughter who is also The Doctor's Grandaughter. Sadly, they named her Olivia rather than Susan.[[/labelnote]]
** An Eighth Doctor ''Series/DoctorWho'' audio titled "An Earthly Child" features Paul [=McGann=]'s real life son as the Doctor's great-grandson (i.e. Susan's son).
** In Eleventh Doctor Creator/MattSmith's first episode, the production staff, looking for an actress to play a young version of new companion Amy Pond, asked Creator/KarenGillan (the adult Amy) if she had any relatives. Karen mentioned a young cousin of hers, Creator/CaitlinBlackwood, and the production team decided to audition her. The two had never met before shooting started. Blackwood appeared again at Amy's wedding at the end of the series, presumably as one of Amy's cousins, even further driving this trope home.
** David Troughton, son to Second Doctor Creator/PatrickTroughton, made an appearance in his father's final story "The War Games" in 1969. He returned as different characters in the 1972 Third Doctor adventure "The Curse of Peladon" and the 2008 Tenth Doctor adventure "Midnight"...not to mention various 21st century audio ''Series/DoctorWho'' dramas.
** Talking of Patrick Troughton, Jack Watling (Professor Travers in the Great Intelligence stories) was the father of Deborah Watling (the Doctor's companion Victoria).
** In the original production of the stage play "Doctor Who and the Daleks: Seven Keys to Doomsday", the companion character is Jenny, played ([[YouLookFamiliar oddly enough]]) by Wendy Padbury (Zoe Heriot). In the Creator/BigFinish version she's played by Padbury's daughter, Charlie Hayes; the two went on to play opposite each other in several "Companion Chronicles" audios.
** In the Series 6 episode "[[Recap/DoctorWhoS32E1TheImpossibleAstronaut The Impossible Astronaut]]", William Morgan Sheppard plays the character of Canton Everett Delaware as he appears in 2011, and his son MarkSheppard plays a younger Canton in 1969. The story goes that they were going to use makeup to make Mark look like an old man before he mentioned his father who'd be a perfect older version of himself.
*** Incidentally this also happened in an ''Series/{{NCIS}}'' episode, "Broken Bird", with Mark Sheppard playing a young version of his father's character in Ducky's flashbacks.
** The little girl in ''Castrovalva'' is played by Souska John, the niece of Caroline John (Liz Shaw).
** MarkGatiss said he wrote "The Crimson Horror" specifically for the mother-daughter duo of Dame Diana Rigg and Rachel Stirling. Gatiss' real-life hubby, Ian Hallard, tends to pop up in this and his other productions, as well.
-->'''[[http://docohobigfinish.blogspot.com/2014/09/robot-of-sherwood-written-by-mark.html Doc Oho]]:''' Mark Gatiss has gone on record to say that he doesn't find work for his husband, Ian Hallard, and that he gets the roles on his merits as an actor. That's all well and good (because he is a genuinely good actor) but it is a remarkable co-incidence that he has just happened to be the best actor for the roles in Gatiss' audio and TV Who and his ''{{Sherlock}}'' scripts too.
* ''Series/DiagnosisMurder'' starred Creator/DickVanDyke as crime solving doctor Mark Sloan, and co-starred his own son Barry Van Dyke as his character's son, police detective Steve Sloan. Other members of the Van Dyke family appeared at various times during the show's run, including Dick's brother Jerry and daughter Stacy in one episode each as Dr. Mark's brother and daughter respectively. Barry's four children all appeared in multiple episodes, although not as Sloan family members: Carey as six different characters in as many episodes; Shane as four, the last of whom became a regular supporting role in the show's concluding months; Wes as three; and Taryn in three episodes. All four appeared together in two separate episodes, which therefore share the highest rating of 6.0 on the Van Dyke Scale...
* ''TheDickVanDykeShow'' also had a few episodes with Jerry Van Dyke as Stacey Petrie, Rob's sleepwalking brother.
* ''Series/TheWonderYears'' featured Danica [=McKellar=] as Kevin's main love interest, and her real-life sister Crystal [=McKellar=] in a recurring role as an unrelated character who was also Kevin's sometime girlfriend.
** Ben Savage (brother of Fred) has a small part in one Wonder Years episode (see ''Series/BoyMeetsWorld'' example below).
* Benjamin Bratt and Julia Roberts were dating when they starred in a memorable episode of ''Series/LawAndOrder''. Mostly notable for the fact that Roberts attempted to seduce Bratt's married character, leading to a venomous and hateful series of betrayals. One wonders if they might not have had some real-life problems to work out...
** Probably, since they didn't stay together.
** Another ''LawAndOrder'' example (sort of) derives from when Jill Hennessy was on ''LawAndOrder'' as Claire Kincaid. Jill was filming some scenes from a crossover with ''Series/HomicideLifeOnTheStreet'' and the filming coincided with the filming of ''LawAndOrder'', so Jill's identical twin sister Jacqueline came in and filled in for Jill during some courtroom scenes.
* ''Series/{{House}}'' co-stars Jesse Spencer and Jennifer Morrison were dating at the same time as their characters, Dr. Chase and Dr. Cameron, started their romantic relationship.
** Inversely, a few months after Chase and Cameron made their relationship official in the third season's finale, Jesse Spencer and Jennifer Morrison decided to call off their engagement.
* Billy Ray Cyrus and his daughter Miley play ''Series/HannahMontana'''s dad and the title character, respectively.
** And his other daughter Noah is an extra.
** Mateo Arias made [[TheCameo a cameo]] appearance as Rico's brother. Rico is played by Moises Arias.
* On ''Series/ICarly'' Gibby (Noah Munck)'s brother Guppy is played by his little brother Ethan.
* A pretty interesting one from ''TheKingOfQueens'': in a flashback to the childhood of Jerry Stiller's character Arthur Spooner, Arthur's father is played by Jerry's son Ben Stiller.
** Jerry Stiller's wife, Anna Meara, plays Spence's mother, who is also Arthur's recurring love interest. Their real life daughter Amy also plays several different characters on the show.
** Also Doug's cousin Danny is played by Kevin James' brother in RealLife, Gary Valentine.
* Madylin Sweeten and her younger twin brothers, Sawyer and Sullivan, play Ally Barone and her younger twin brothers, Geoffery and Michael, respectively, on ''EverybodyLovesRaymond''
* Simon Baker's wife appeared in an episode of her husband's hit show ''TheMentalist'' as the widow of that episode's victim.
** Tim Kang's wife plays one of the women in the bar during Cho's InstantSeduction scene in "Crimson Casanova" (she's the one who walks off in disgust when he suggests a threeway), a RealitySubtext which makes the scene even more hilarious.
* ''Series/GreysAnatomy'''s Derek Shepherd's mother is played by Tyne Daly; ironically, Daly is tied by parental roots to two actors from ''PrivatePractice'', one fictional (she played Amy Brenneman (Violet)'s mother in ''Series/JudgingAmy'') and one real (Tim Daly (Pete) is Tyne's baby brother).
* In ''PrivatePractice'', [[Theatre/{{Wicked}} Idina Menzel]] plays a patient's mother and a potential love interest. At the times, Menzel was the real-life wife of [[{{Rent}} Taye Diggs]], who plays Dr. Sam Bennett.
* In ''ItsAlwaysSunnyInPhiladelphia'', Charlie Day's character has an unrequited crush on a waitress played by his real-life wife, Mary Elizabeth Ellis. Also, Rob [=McElhenney=] (Mac) is married to Kaitlan Olson (Sweet Dee); they met when she auditioned for her part. In another episode with a ShoutOut to OneFlewOverTheCuckoosNest, the person who was playing the role of "Chief" was actually Will Sampson's son.
** Additionally, in the episode "Mac Bangs Dennis' Mom" Danny [=DeVito=]'s daughter Lucy plays the waitress Frank lusts after in the restaurant (as his date talks about how wonderful it is to have children), as well as the young woman who compliments "DB" in "The Gang Finds a Dumpster Baby".
** And Glenn Howerton's wife plays the woman whom Dennis manipulates and torments in "The DENNIS System"
* In ''Series/FamilyTies'', Tracy Pollan played the girlfriend of Michael J. Fox's character. In ''Bright Lights Big City'', Tracy Pollan played the cousin of Michael J. Fox's character. The two of them married later that year, and are still married to this day. Tracy Pollan has also made a guest appearance on ''SpinCity'', as the high school flame of Michael J. Fox's character.
** Before Tracy Pollan, Michael J. Fox had dated Nancy [=McKeon=]. The two of them played love interests on two [[MadeForTVMovie made-for-TV movies]], ''High School USA'' and ''Film/PoisonIvy''.
** In ''Life With Mikey'', Michael J. Fox is the titular character. His sister, Kelli Fox, has a minor role.
* On ''Series/{{Heroes}}'', the actors playing Ted Sprague and Sandra Bennet are married in real life. In one episode, Ted threatens to kill Sandra. In the episode commentary, the actor playing Ted observes, "Yeah, our kids aren't gonna be allowed to watch this one."
** The fact that Hayden Panettiere and Milo Ventimiglia were dating is going to make for some awkward television considering that Milo's ''Series/{{Heroes}}'' character is ''her character's uncle''.
** If those two end up marrying, I doubt they'll let their kids watch the recent episode [[spoiler:where Future Claire kills Future Peter]]. Assuming they let their kids watch the show at all.
* On the last couple of seasons of ''Series/GrowingPains'', Chelsea Noble played the romantic interest of Kirk Cameron's character. They ended up getting married in the show, and then later married in RealLife.
** And then even later, Noble played Cameron's love interest in the short-lived WB series ''{{Kirk}}''.
** They've since appeared together in the ''LeftBehind'' movies. (Although Cameron plays the main character and Noble plays...the anti-Christ's girlfriend.) They're both now evangelical Christians.
** ...and even worse than that, reportedly, Cameron won't even kiss anyone other than Noble now. She's supposedly in ''Fireproof'' (uncredited) in Cameron's kiss scenes with his movie wife (played otherwise by Erin Bethea).
* In the ''Series/SabrinaTheTeenageWitch'' TV series, Melissa Joan Hart's real life sister Emily played Sabrina's cousin Amanda. She then played Sabrina on the animated series while Melissa Joan Hart played her aunts.
* On the 1980s British TV series ''A Fine Romance'', main characters Mike and Laura were played by real-life spouses Michael Williams and Judi Dench.
* In the ''Series/StarTrekTheNextGeneration'' episode "The Inner Light", the son of Kamin, the person whose life Picard is experiencing, was played by Patrick Stewart's son Daniel.
** Creator/WilWheaton's younger siblings Jeremy and Amy played Mason and Tara, two of the children who were abducted along with Wesley in "When the Bough Breaks".
* Father-son example: in ''Romeo!'', MasterP makes occasional guest appearances as the father of the title character, played by his son Li'l Romeo.
* Extreme example: Michael, Nat, and Alex Wolff (father and sons) play a father and his two sons in ''Series/TheNakedBrothersBand''.
** On top of that, Jesse, Alex's [[MayDecemberRomance May-December]] girlfriend, is actually his [[KissingCousins cousin]].
* The character of Compo Simmonite died on ''LastOfTheSummerWine'' following the death of the actor Bill Owen. Several episodes later and after the funeral, Compo's long-lost son moves into town and is played by Bill Owen's real-life son Tom Owen.
* Pauline Quirke and Linda Robson, who played sisters Sharon and Tracy in ''Birds of a Feather'', have been friends since primary school, enabling the opening credits to use genuine photos of them growing up together.
* Another extreme example: a two-parter of ''Series/TheBill'' features three generations of the Woodward acting dynasty. Edward (an old crook), his son Tim (as his love child) and Tim's son Sam (as the first character's grandchild, not via the second).
* ''{{Kojak}}'' featured Telly Savalas and his brother George as Det. Stavros.
* ''Series/PowerRangersZeo'' introduces us to David Trueheart, Tommy's long-lost brother... played by Eric Frank, actual brother to Tommy's actor, Jason Frank.
* ''Series/{{Mash}}'' star Alan Alda's father Robert Alda starred as a visiting/rival surgeon a couple times. One of the times, Alan Alda's brother also guest-starred as a medic.
** The photograph on Col. Potter's desk, supposedly of Potter's wife Mildred, was actually a picture of Harry Morgan's real-life wife, Eileen Detchon.
* In ''Series/DueSouth'' Fraser's (Paul Gross' character) mother was played by Martha Burns ...who is Paul Gross' wife. They also starred together in the series ''SlingsAndArrows'', as former lovers.
* ''Series/BuffyTheVampireSlayer'' took advantage of the fact that Nicholas Brendon (Xander Harris) has an identical twin, in an episode where there are two Xanders.
** Kelly Donovan (Brendan's twin) stood in for Nicholas Brendon on multiple occasions during Buffy's production run. Besides the episode mentioned above, Donovan subbed for his brother during the fight scenes in the episode "Intervention", because Nicholas Brendon had pneumonia at the time.
** AdamBusch (Warren) and Creator/AmberBenson (Tara), respectively, were dating, and JossWhedon actually told Adam, "You're gonna kill your girlfriend," to which the reply was "Warren gets a girlfriend?" "No, I mean your real girlfriend." Eight years later, by the way, they're still together. This relationship was actually the inspiration somewhat for the Buffy fanfic ''[[http://www.fanfiction.net/s/3460966/1/Difficult_to_Fight_Against_Anger Difficult to Fight Against Anger]]''.
** Alyson Hannigan crossed over to guest star on Series/{{Angel}} alongside her now-husband Alexis Denisof
** David Boreanaz' wife Jaime Bergman appeared in one season 5 Angel episode.
** ''{{Dollhouse}}'' similarly took advantage of Enver Gjokaj (Victor) having an identical twin brother. He stood in as the second Victor in a dream sequence.
*** ''Dollhouse'' had another example of real-life relatives: the series finale has Eliza Dushku's younger brother Nate as Clive Ambrose's latest body. Her real-life boyfriend, Rick Fox, also cameoed.
*** Nate was also the gunman in one of Series/{{Angel}}'s flashbacks in Eliza's final appearance on that show.
* ''Series/{{Monk}}'': A lot of Tony Shalhoub's real relatives appeared on the show at different points.
** Brooke Adams, Tony Shalhoub's wife, has appeared as four different characters on the show:
*** In "Mr. Monk and the Airplane", Brooke plays Leigh Harrison, a flight attendant who is driven crazy by Monk's antics. She is later interviewed by James Novak in "Mr. Monk's 100th Case", where it is shown that she has developed a fear of flying and also was driven to drinking, which was also implied by her final appearance in the former episode.
*** In "Mr. Monk and the Kid", Brooke plays Abigail Carlyle, whom Monk and Natalie interview after her son, violinist Daniel Carlyle, is discovered to have been kidnapped and the kidnappers amputated one of his fingers to send back to them as a message.
*** In "Mr. Monk Visits a Farm", Brooke plays Sheriff Butterfield, a county sheriff. All of a sudden, the scene where Monk is roped into going square dancing very terribly with her (while looking visibly uncomfortable for the entire scene) becomes a thousand times funnier, especially since he brings up Trudy during the scene. In her first crossing paths with the leads (while Monk and Randy are looking at Randy's uncle's old pickup truck), she even winks at Monk, though it's hard to see if this is her quickly breaking character.
*** In "Mr. Monk and the Badge" as Edith Capriani, a CrazyCatLady that Monk gets fed up with for pulling him away from other cases.
** Tony's brother Michael Shalhoub has played three characters throughout the series' run:
*** In "Mr. Monk and the Missing Granny," he plays Ron Abrash, a former radicalist who Monk and Captain Stottlemeyer question as a person of interest in a kidnapping. Which makes the part where Monk says, "I've been smoking THE TRUTH, man!" that much funnier when you consider just exactly who Tony is saying this line to.
*** In "Mr. Monk Bumps His Head," Michael plays Ned, the beekeeper whose farm Roger Zisk crashes his car into when trying to cover up bee stings that he'd received the night before when dumping Debbie Barnett's dead body on a roadside.
*** In "Mr. Monk Is the Best Man," Michael is the minister who presides over Leland and T.K.'s wedding ceremony.
** Tony's sister Susan Shalhoub Larkin appears as Linda Kloster's housekeeper in "Mr. Monk and the Genius" (the one who drops the tray and discovers the body).
* In addition to ''Monk'', Brooke Adams also guest-starred on ''Series/{{Wings}}'' as a nun who is helped by Shalhoub's character Antonio.
* Speaking of ''Wings'', in addition to Shalhoub and Adams, a handful of episodes featured guest spots by relatives of the cast.
** Tim Daly's sister Tyne played a wealthy woman who attempts to make Brian a kept man.
** Tim Daly's wife, Amy Van Nostrand, played a woman in a married couple who befriends the Hacketts.
** Amy Yasbeck's husband John Ritter played Casey's estranged husband Stuart.
* Emily, the estranged daughter of Gerry Standing in ''NewTricks'' is played by Dennis Waterman's daughter Hannah.
** Subversion: [[spoiler:but Emily's not actually his.]]
* James Roday and Maggie Lawson, who are dating in real life, star in the ''Fear Itself'' episode "In Sickness and in Health" as a couple about to get married. The two are also castmates in ''{{Psych}}'', and their characters officially entered a relationship in Season 5.
** The episode "Bollywood Homicide" had a client of the week and his brother as the central part of the episode's plot. The brothers are played by real-life cousins Sendhil Ramamurthy and Jay Chandrasekhar.
* ''Series/VeronicaMars'' Logan Ecchols' parents are played by real-life husband and wife Harry Hamlin and Lisa Rinna.
* ''Series/TheOfficeUS'': Michael Scott's girlfriend Carol in seasons 2 & 3 is played by Creator/SteveCarell's wife, Nancy Walls.
* ''Series/ArrestedDevelopment'': The woman Gob (Will Arnett) marries on a dare is played by Arnett's wife, Creator/AmyPoehler. The situation was reversed years later when Poehler got her own show, ''Series/ParksAndRecreation'', and Arnett appeared in one episode as Leslie (Poehler)'s horrible blind date.
** ''Arrested'' was fond of this trope. In a later episode, Michael (Jason Bateman) hires a woman, played by Bateman's real-life sister Justine, to work at the Bluth Company. He thinks she is his [[spoiler:long-lost sister Nellie]]; she's actually a [[spoiler:prostitute]].
--->'''Michael:''' Marry me! ... That's so wrong... on ''so'' many levels.
** In season 4, it turns out that [[spoiler: Tony Wonder and Sally Sitwell, played by married couple Ben Stiller and Christine Taylor, are a couple. They both appeared in the show earlier, but as unrelated characters]].
* Tatort (NDR; Hannover): The actress Maria Furtwängler who plays KHK Charlotte Lindholm is the daughter of Kathrin Ackermann who portrays Charlottes mother Annemarie Lindholm.
* Semi-example: Shirley Jones, who is/was David Cassidy's stepmother, played his mother in ''ThePartridgeFamily''. AIR neither was consulted on the casting of the other.
* After he gained more creative control on ''{{Sliders}}'', Jerry O'Connell got his real-life brother added to the regular cast, playing his long-lost brother. When Jerry departed the show, his brother went with him.
** Charlie O'Connell would later make an appearance as the brother of Jerry O'Connell's character in CrossingJordan.
* In the ''Series/RedDwarf'' episode "Timeslides" Lister's ''younger self'' was played by Emile Charles, Craig Charles's younger brother. Baby Lister in "Oroboros" was played by Danny John-Jules's nephew, Alexander John-Jules.
** The mechanoid and blob incarnations of Camille in "Camille" were played by Robert Llewellyn's then-girlfriend (now wife) Judy Pascoe. In his memoir ''The Man In The Rubber Mask'' Llewellyn claims that the publicity shot of Kryten and Camille is in his parents' photo album: "That's our elder son and his wife and children, that's our daughter and her children, and that's our middle son who's a robot and his girlfriend."
* In ''StElsewhere,'' Dr. Craig and his wife were played by real-life husband and wife William Daniels and Bonnie Bartlett.
** Briefly reprised in ''Series/BoyMeetsWorld'', where Mr. Feeney (Daniels) fell for the college's dean (Bartlett). In fact, Daniels and Bartlett have played a romantic couple on no less than four occasions: ''Killer on Board'' (1977), ''Touched By an Angel'', ''Boy Meets World'', and ''StElsewhere''. Apparently, they are a living aversion to the CoupleBomb both in real life and onscreen (they've been married since 1951).
* Another ''Series/BoyMeetsWorld'' example: Topanga's parents were played by the husband-and-wife Michael [=McKean=] and Annette O'Toole [[TheOtherDarrin for one episode]]. Also, Ben Savage's brother Fred Savage appears in one episode as a creepy lecherous college teacher.
* The first season ''TheManFromUNCLE'' episodes "The Quadripartite Affair" and "The Giuoco Piano Affair" were two of the relatively few episodes that gave Illya Kuryakin (played by David [=McCallum=]) the GirlOfTheWeek. She was played in both episodes by Jill Ireland, who was at the time of filming married to [=McCallum=].
* On ''Series/{{Lost}}'', Benjamin Linus is played by Michael Emerson. His wife Carrie plays Ben's mother Emily. Thankfully, {{Squick}} is avoided because Emily [[spoiler:dies in childbirth]] and thus only appears during baby Ben's birth and [[spoiler:as a hallucination on the island]] to young Ben.
* Father and son Rene Auberjonois and Remy-Luc Auberjonois played father and son in an episode of ''Series/LALaw''.
** Speaking of ''LA Law'', husband-wife actors Michael Tucker and Jill Eikenberry were both regulars on that show and also appeared together in several late '80s/early '90s TV movies that they produced.
* ''Series/HowIMetYourMother'' has several recurring characters played by relatives of the main cast. Sandy Rivers, Robin's co-anchor, is played by Alyson Hannigan's husband Alexis Denisof. Scooter, Lily's high school boyfriend and co-worker, is played by Creator/NeilPatrickHarris's husband David Burtka. Blauman, a GNB employee, is played by Cobie Smulder's fiancee (and the father of her child) Taran Killam. Josh Radnor also ended up dating Lindsay Price, who played one of his [[GirlOfTheWeek girls of the week]].
* The {{Heartwarming Orphan}}s from ''Series/TheColbertReport'' ChristmasSpecial are Madeleine, Peter, and John Colbert. Madeleine also appeared aged eight in the [[http://www.thedailyshow.com/video/index.jhtml?videoId=108251&title=Tanks-A-Lot Getty Oil]] segment on ''Series/TheDailyShow'', producing some adorable outtakes.
-->'''Stephen:''' How big was your profit margin last year?\\
'''Madeleine:''' I don't know what that means, Daddy.
** His brother Ed Colbert is a copyright lawyer, and appeared on the show during the Shepard Fairey 'Hope' poster fair use debate.
* Jon Stewart's son, Nathan, has appeared on ''Series/TheDailyShow'' at least twice. [[http://www.thedailyshow.com/watch/thu-march-22-2007/viacom-vs--youtube The funniest moment]] being when he played a cheap Youtube version of his father. Jon's inability to hold his laughter when the camera cut back was priceless.
* ''Series/GossipGirl'' stars Penn Badgley (Dan) and Blake Lively (Serena) date in real life as well as in the show.
** Someone might say that the ''Series/GossipGirl'' one-episode Vanessa/Chuck hookup and kiss might be imputable to the two actors playing the characters, Jessica Szohr and Ed Westwick, dating, but given the fact that the writers of the show seem to be on crack most of the time, that's highly debatable. Also, the set brought Sebastian Stan (Carter Baizen) and series regular Leighton Meester (Blair Waldorf) together.
* Toward the end of its run ''One Day at a Time'' had as regulars both Nanette Fabray and her niece, Shelley Fabares, providing an interesting side-by-side example of how anglicizing your name for the stage seemed less necessary from one generation to the next. Casual viewers didn't always know they were related, especially if they didn't realize their last names are pronounced the same.
* Real-life couple Michael and Susan Hogan played the parents of Dana Fairbanks in ''Series/TheLWord'', and the parents of Myka in ''{{Warehouse13}}''
* Most of the random characters on ''TheMightyBoosh'' are friends and family of Noel and Julian. The relative with the largest role would be Vince's girlfriend's nephew who plays the shaman Kirk. Or maybe Naboo, who is played by Noel's brother.
* An interesting but slightly obscure example: Martin Sheen's daughter plays one of the secretaries of the Oval Office in ''Series/TheWestWing''. In the season finale, the President asks about her mother, and then said, "Tell her I'm looking forward to seeing her again sometime soon, would you please?", which is actually a shout out to his own wife.
** Martin Sheen also appeared on an episode of ''Series/TwoAndAHalfMen'' in which he played the father of Charlie's StalkerWithACrush. Charlie is, of course, played by [[TheDanza Charlie Sheen]]. In the same episode, Martin Sheen's character gets in a relationship with the mens' mother, much to their horror.
** And Emilio Estevez has also appeared on ''Two and a Half Men''.
* On ''Series/{{Seinfeld}}'', [[Creator/JuliaLouisDreyfus Julia Louis-Dreyfus]]'s half-sister Lauren Bowles made occasional appearances as a waitress in the coffee shop that the characters frequent.
** Speaking of Julia Louis-Dreyfus, she and her future husband Brad Hall were cast mates on ''SaturdayNightLive''. Several years later, Julia guest-starred on an episode of ''TheSingleGuy'', which was created and produced by Hall.
** Lauren was also a main cast member on Julia's short-lived ''Watching Ellie''.
* ZooeyDeschanel guest-starred in an episode of ''Series/{{Bones}}'', which stars her sister Emily, as Emily's character's cousin. The writers took the golden opportunity to {{lampshade}} the ''hell'' out of this during said episode.
-->'''Everyone, upon seeing the two in the same room:''' You two could be sisters!
* The French TV series ''Series/{{Kaamelott}}'' seems to have been cast largely from creator (and lead actor) Alexandre Astier's family. Note they're all professional actors anyway, so it hardly hurts the show. Alexandre Astier plays KingArthur and:
** his father plays Arthur's father-in-law, Léodagan;
** his mother plays Arthur's mother-in-law, Séli;
** his stepmother plays Arthur's mother, Ygerne;

* In the first season of ''Series/GetALife'', Chris Elliott's character's father was played by his real-life father [[Radio/BobAndRay Bob Elliott]].
* The second and third seasons of ''Series/SeaQuestDSV'' has Peter and Michael [=DeLuise=] on the main cast, though their characters are not related. In one episode, Creator/DomDeLuise appears as the father of Michael's character, and David [=DeLuise=] has a small cameo.
* Troian Bellisario, who plays Sara , is a (step) sibling to Sean Murray, who plays Timothy [=McGee=], her character's brother, in ''{{NCIS}}''. A third sibling, Michael, had a recurring role on the show but shared no scenes with either sibling. All three actors also appeared on Series/{{JAG}}, though in different roles, and producer DonaldPBellisario is their father. a fourth sibling Chad W. Murray plays Seaman [=Mcdonald's=] corpse in ''Series/{{NCIS}}'' episode the Immortals and the unnamed redhead that picks Gibbs up in the silver convertible is Sean Murray's real-life mother Vivienne Bellisario. Nepotism much?
** Also in ''NCIS'', Mark Harmon's son plays young Gibbs.
* In ''Series/{{Castle}}'', Esposito and Castle (Jon Huertas and NathanFillion respectively) have been teasing Ryan (Seamus Dever) about his girlfriend, who up to this point has been TheGhost.

* Ian Lithgow, the son of John Lithgow, played one of Dick's students in ''ThirdRockFromTheSun''.
* Alton Brown frequently has members of his family make appearances on ''Series/GoodEats''. While most of his on-air family is portrayed by actors or members of the production crew, his late grandmother, mother, and daughter Zoey did make appearances as themselves. On a recent episode, Zoey Brown appeared as Alton's granddaughter which is humorous because she was effectively playing her own daughter (Zoey being Alton's only child).
* Marlo Thomas' 1960s sitcom ''ThatGirl'' had Danny Thomas in a brief cameo as a priest, just so she could call him "father".
* ''Series/MysteryScienceTheater3000'', at the end of its ''{{Laserblast}}'' episode, had Trace Bealieu's father in a brief cameo as an extremely-aged Dr. Forrester.
** Additionally, Mike Nelson's real-life wife, Bridget Jones ([[NamesTheSame no, not]] ''[[NamesTheSame that]]'' BridgetJones) appeared several times, including as MrBNatural, Lisa Loeb, Nuveena, Flavia, and Slicer the Nanite. She was also one of the actresses who portrayed Magic Voice before Mary Jo Pehl took over permanently. Bridget was also one of the show's writers, including a stint as a full-time member of the writing staff from season 4 onward.
* Peter Barlow, the repeatedly [[TheOtherDarrin Other Darrined]] son of William Roache's character Ken Barlow in ''CoronationStreet'', was briefly played by Roache's son Linus in the 1970s. Linus Roache returned to the Street in 2010, now playing a completely different son, long-lost Lawrence Cunningham. Lawrence's son is played by Linus's ''brother'', James. And James Roache also appeared in the docudrama ''The Road To Coronation Street'', as [[IdenticalGrandson a young William Roache]]!
* The ''Series/{{Scrubs}}'' episode "My Unicorn" had John Bennett Perry as the PatientOfTheWeek and his son Matthew Perry as the patient's son. [[spoiler: Except it turned out Gregory wasn't really Murray's father.]] That episode also cameoed Matthew's cousin Anthony as "Old Murray".
** Series creator Bill Lawrence is married to Christina Miller (Jordan), who also did voice-over work for his show ''CloneHigh''. The wedding video that Cox watches in Miller's character's first appearance is actually Bill and Christina's, which is why only she can be seen. Lawrence also wrote both of their pregnancies into the series.
* ''Series/{{Thirtysomething}}'' had married couple Ken Olin and Patricia Wettig, playing the respective spouses of the other two central characters. They later play a couple in ''Brothers & Sisters''.

* In ''Series/TheXFiles'' episode "Hollywood A.D.", a movie is made based on Mulder and Scully's lives as paranormal FBI agents. Tea Leoni is cast as the movie version of Scully, and it is mentioned (jokingly) that she has a crush on Mulder. Tea Leoni being David Duchovny's wife, obviously. Of course, David Duchovny also wrote ''and'' directed that episode...
* In the season 3 premiere of ''Series/{{Leverage}}'', Nate [[spoiler:helps a young inmate escape from jail.]] The inmate is played by Edwin Hodge, brother of Aldis Hodge, who plays Hardison.
* The 90s series ''BrotherlyLove'' was pretty much contrived for brothers Joey, Matthew and Andrew Lawrence to play themselves.

* In ''Series/TheShield'', Vic Mackey's daughter Cassidy is played by Michael Chiklis's real life daughter Autumn Chiklis.
* Marg Helgenberger's now ex-husband appeared in two episodes of Series/{{CSI}}.
* Chris Masterson appeared on his brother Danny’s series ''Series/That70sShow'' as an unrelated character. They also played brothers on one episode of ''WhiteCollar''.
* Ali Marsh plays a recurring role as a psychiatrist on ''InPlainSight'', which stars her husband Frederick Weller. Bonus points because their characters went on a date once, but she wasn't interested.
* ''Gimme A Break'': During the last three seasons, Matthew Lawrence joined his older brother, Joey, as Joey's [[TheDanza (the character)]] little brother, Matt.
* In ''Series/DadsArmy'', Pike's girlfriend Ivy was played by Ian Lavender's real-life wife. Arthur Lowe's wife, Joan Cooper, [[TheOtherDarrin also took over]] the role of Dolly Godfrey towards the end of the series.
** Lowe and Cooper were well known for this trope and often performed in repertory theatre together. Towards the end of Lowe's life, he would often agree to take roles only if his wife could act alongside him, and they were appearing in a play together when Lowe [[FatalMethodActing died backstage.]]
* In the fourth season of ''Series/NurseJackie'', Bobby Cannavale plays BadBoss Mike Cruz while his real-life son Jake plays Cruz's addict son Charlie. [[BlatantLies Hilarity ensues]] when [[spoiler:Charlie overdoses in the season finale and Cruz fails to revive him.]]

* Creator/XanderBerkeley and Sarah Clarke from ''Series/TwentyFour'' (George Mason and Nina Myers) married between Seasons 1 and 2. This meant that Xander got to interrogate his own missus in the second run. In addition, as an inside joke, a fake passport for Nina in Day 3 has the name "Sarah Berkeley".
* It seems like Stiles and Lydia might have a little trouble with their relationship on ''Series/TeenWolf'' as the sheriff (Linden Ashby) and Lydia's mom (Susan Walters) are married IRL and have been for nearly 30 years now.
* In ''Series/SledgeHammer'', humor about the title character's ex-wife were made a ''lot'' (although the reason for the divorce was [[NoodleIncident never fully explained]]). When she actually appeared in the last season of the show, the actress was the lead actor's actual wife.

* On ''Series/{{Hannibal}}'' Jack Crawford's wife Bella is played by Gina Torres, who is married to Laurence Fishburne in real life as well. Makes the secret Bella was keeping from Jack all the more painful when you know they're ''actually'' married and playing a married couple going through that.
** Both Torres and Fishburne also appeared on ''{{Series/CSI}}'', but Gina appeared in season four, long before Fishburne bevame the series' star.
* Genevieve Cortese met JaredPadalecki while playing the demon, Ruby, during Season Four of ''{{Series/Supernatural}}''. By Season Six, she's guest staring as herself in a AlternateUniverse episode and married to Padalecki -- in real life and on the show. Whew.
* Series/{{Sherlock}} and Mycroft's parents are played by Wanda Ventham and Timothy Carlton, Creator/BenedictCumberbatch's own parents.
** Mary Morstan (Watson's fiancee/wife) is played by Amanda Abbington, who is Martin Freeman's real-life partner.
** Sherlock as a child is played by one of Stephen Moffat's sons.
** In a WhatCouldHaveBeen example, Mark Gatiss's partner, Ian Hallard, had a minor role as the barrister defending Moriarty in ''The Reichenbach Fall''.

As the Queen is played by Jane Seymour and the girl is played by her daughter, this is understandable, and even lampshaded in one scene--"You remind me of myself at that age!"

[[folder: Music]]
* BillyJoel wrote ''Uptown Girl'' as an ode to Christie Brinkly, his soon-to-be wife, and she later starred in the song's music video.
** He also wrote "Just the Way You Are" for his earlier spouse Elizabeth.
* {{Eric Clapton}} wrote "Wonderful Tonight" based on a comment he made to his wife when she was taking too much time getting ready for a function. The song turns the comments on their heads and thus was born one of the all-time great romantic ballads. Also regarding Clapton, his smash hit "Layla" was an {{anguished declaration of love}} toward his close friend {{George Harrison}}'s then-wife Patti Boyd, who Clapton was infatuated with. They later got together, though the relationship didn't last.
* The late Minnie Ripperton wrote her one big hit "Loving You" for her daughter Maya, who she [[TearJerker never got to see grow up]]. Maya -- as in the comedic actress {{Maya Rudolph}} -- grew up to become famous in her own right.
* On a lighter note, {{Stevie Wonder}} wrote "Isn't She Lovely" for HIS own daughter.
[[/folder]]

[[folder:Radio]]
* Husband-and-wife teams were remarkably common in the golden age of radio, probably due to the number of radio acts that originated on vaudeville where family acts were common. Notable husband-and-wife radio teams include:
** Jim and Marion Jordan (FibberMcGeeAndMolly)
** George Burns and Gracie Allen
** [[TheJackBennyProgram Jack Benny and Mary Livingstone]]
** Goodman and Jane Ace (the Easy Aces)
** Fred Allen and Portland Hoffa (Town Hall Tonight)
* Ben Lyon and Bebe Daniels (''Life With The Lyons'') on TheBBC at the same period.
* In the 1990s, Jeremy Hardy and his then wife Kit Hollerbach in ''Unnatural Acts'', later titled ''At Home With The Hardys'' in imitation of the above.
* In the AudioPlay/BigFinishDoctorWho story "An Earthly Child", [=McGann=]'s real-life son guest-stars as the Doctor's great-grandson.
[[/folder]]

[[folder:Theater]]
* Many high school musicals will use the younger siblings of cast members to fill children's parts, mostly because it cuts down on scheduling issues. If one child can make it to all of the rehearsals, chances are their sibling can as well. Of course, sometimes the younger child is very good in their own right, and may even have a substantially bigger part than their brother or sister.
* One memorable production of ''Don Giovanni'' cast identical twins as the title character and his manservant Leporello. Since there is a lengthy sequence in which Leporello disguises himself as the Don and fools everyone, this was a stroke of casting genius.
[[/folder]]

[[folder:Video Games]]
* The ending in the Japanese version of ''MetalGearSolid4'' featured AkioOhtsuka as Solid Snake and [[spoiler:his father Creator/ChikaoOhtsuka as Big Boss]].
* Likewise, the Japanese release of ''VideoGame/KingdomHeartsBirthBySleep'' uses the immediately-above same two actors for plot relevance; with Akio Ohtsuka having voiced Xehanort in the entire ''KingdomHearts'' series by that point, it was only natural to cast [[spoiler:Chikao Ohtsuka as Master Xehanort, who commits GrandTheftMe on Terra at the end of Terra's scenario, effectively becoming present-day Xehanort. Apparently, Akio represents a younger Chikao.]]
* ''VideoGame/{{Persona 3}}'' has two cases. One both of the Velvet Room attendants are voiced by the [[Creator/YuriLowenthal main]] [[Creator/LauraBailey protagonists]] [[TaraPlatt wife]]/[[Creator/TravisWillingham husband]], with the Female Protagonist and Theodore combo likely being a CastingGag referencing this. Mitsuru also shares a voice with Elizabeth and is potential love interest for the Male Protagonist as well. Along with Ryoji hitting on her being extra-humorious.
* Creator/KenichiSuzumura and Creator/MaayaSakamoto were married during the development of Saisei-hen. In ''VideoGame/SuperRobotWarsUX'', Shinn and Lunamaria get an exclusive Combination Attack.
* The voice actors for [[VideoGame/DeusExHumanRevolution Adam Jensen and his girlfriend Megan Reed]] are real life married couple Elias Toufexis and Michelle Boback.
* [[VideoGame/BinaryDomain Dan Marshall and his eventual love interest Faye]] are voiced by Creator/TravisWillingham and Creator/LauraBailey.
[[/folder]]

[[folder:Web Original]]
* [[WebVideo/AtopTheFourthWall Linkara]] does this a lot -- not surprising, since as an Internet reviewer he can't exactly afford to hire people on a regular basis. Thus far, he's utilized his parents, brother, and girlfriend at various points. (As examples: his father as an older version of him; his mother as a Starfleet commander; and [[WebVideo/IronLiz his girlfriend]] as... herself, more or less.)
* Creator/DougWalker's brother is The Other Guy (Rob Walker), who mostly works behind the camera, but does appear on screen as various characters on occasion.
** His father (who also does most of the show's original music) also had cameo appearances in ''WebVideo/SuburbanKnights'' (News anchor Larry Prince and father of Doug's character Lori) and ''WebVideo/ToBoldlyFlee'', as well as the review of the movie ''{{Film/Devil}}''.
* Scott [=McClure=], the aspiring filmmaker behind WebVideo/TheJokerBlogs, also uses this, probably for the same reasons as Linkara.
* [[WebVideo/TheSpoonyExperiment Spoony]] has occasionally had his brother appear on his show. Things are sadly averted in the case of his then-girlfriend Scarlett, who made one appearance in a now-removed video. His FanDumb mocked her so much that he replaced the video with an article calling them out on it and never put her in another video again (though she was the webmistress of his site).
* While WebVideo/TheNostalgiaChick and WebVideo/ToddInTheShadows both had their own webshows, when they began dating, they started a RunningGag/subplot in both their shows, in which the Chick is terrifyingly obsessed with hooking up with Todd while he is callously indifferent to her. A similar joke was used in the massive review for the ''Les Miserables'' musical movie, in which Elise and Paw (who are engaged in real life) fall in LoveAtFirstSight and become SickeninglySweethearts as a result.
* Gamer and Meddler's players in ''RolePlay/WeAreAllPokemonTrainers'' are RL siblings, as are Joseph and Emma's.
[[/folder]]

[[folder:Western Animation]]
* On ''WesternAnimation/AmericanDad'', Creator/RachaelMacFarlane, voice actor for Hayley, is the sister of series co-creator (and voice actor for Stan and Roger) Creator/SethMacFarlane.
** She's also done a number of additional voices on ''WesternAnimation/FamilyGuy'', including Stewie's love interest Olivia ([[IncestuousCasting Stewie is voiced by Seth]]).
* On ''WesternAnimation/DrKatzProfessionalTherapist'', Laura Silverman and H. Jon Benjamin (respectively, surly secretary Laura and Ben, the 24 year old slacker son of Dr. Katz who repeatedly and unsuccessfully asks out Laura) were dating when the show started, but broke up during the middle of the show's run.
* [[Series/{{Mash}} Mike Farrell]] and [[http://en.wikipedia.org/wiki/Coach_(TV_series) Shelly Fabares]], who play the Kents in SupermanTheAnimatedSeries and JusticeLeague, are married in real life.
* The late Wayne Allwine and Russi Taylor, the voice actors of Mickey and Minnie Mouse respectively, were married until Wayne's death.

** The younger voices of Marceline and Bubblegum are sisters.
* ''WesternAnimation/{{Recess}}'': In the episode "The Dude", Mr. Dudikoff is played by Joey Lawrence, and his little brother, Andrew Lawrence, was the voice of T.J. from 1998 to 2001.
** In the ''Lilo & Stitch'' crossover episode (from 2005, four years after the show ended and two years after the DirectToVideo movies), Gus was [[TheOtherDarrin replaced by]] Zach Ewing, due to his previous voice actor, Courtland Mead, going through puberty. Zach's older brother, Blake Ewing, was the voice of Menlo in the show. (He also did the singing voices for Gus and T.J. in the credits of ''WesternAnimation/RecessSchoolsOut''.)
* ''WesternAnimation/TotalDramaIsland'' (Italy): Heather is the mother of Trent and Cameron.
* On ''WesternAnimation/BobsBurgers'', the Pesto Twins are voiced by sisters Sarah and Laura Silverman.
* In the second to last scene of the episode "The Knights of Tomorrow!" from ''WesternAnimation/BatmanTheBraveAndTheBold'', the future Batman Damian Wayne is voiced by Diedrich Bader (who voiced the current Batman) and his son Robin is voiced by Sebastian Bader (Diedrich's real son).
* Creator/StanLee plays himself in the final episode of ''WesternAnimation/SpiderManTheAnimatedSeries''. His wife, Joan Lee, already played the RecurringCharacter Madame Web (and there's a bit of mutual attraction between Stan-the-character and Madame Web).
* Creator/JessicaWalter, who plays Malory in ''WesternAnimation/{{Archer}}'', is married in real life to RonLeibman, who plays Malory's Season 4 husband Ron Cadillac. The humor is compounded with a touch of IronyAsSheIsCast; while Malory and Ron appear to have had a rush wedding within a few weeks of meeting and have a woefully mismatched relationship based on constant bickering, Walter and Leibman have been happily married since 1984.
* Nick Offerman is the voice of ''WesternAnimation/AxeCop'' and his wife Megan Mullally voices most of the female characters in the show.
* Wilykat and Wilykit's father in ''WesternAnimation/ThunderCats2011'' is voiced by John Pirruccello, father of Wilkyat's voice Eamon Pirruccello.
