-->-- ''DoctorWho: A History'' by Lance Parkin

Celebrity Paradox is the fact that celebrities and fictional characters/works don't exist as media within works about or related to them. So, in ''TheSarahConnorChronicles'', Arnold Schwarzenegger doesn't exist and is not the governor of California. There's no Governor {{Terminator}}. Or, in the world of ''[[DarkKnightTrilogy Batman Begins]]'', the Comicbook/{{Batman}} comics never existed, and neither did Christian Bale. In modern updates of a work, the original may be unheard of. This is an [[OmnipresentTropes Omnipresent Trope]], and there are notable LampshadeHanging and [[SubvertedTrope subversions]] on part of a handful of cheeky writers who get a li'l kick out of toying around with the concept, such as having the character meet the actor/actress playing them somehow or giving out a ShoutOut to the original source.

This avoids such awkward issues as why the plucky hero isn't constantly asked for autographs. It can become extremely awkward when the show is set amongst the showbiz industry, and the stars and writers become famous enough to be on the scene where the show finds itself. Also, if a larger-than-life celebrity was chosen to play a nerd, a geek, or a loser (for example, Hilary Duff in ''A Cinderella Story'') -- that would also be extremely awkward.

To what extent this is done is a subject for discussions amongst fans. Do the actors themselves not exist? Do other works the actors have appeared in exist? If they do, who starred in them? It's probably best not [[BellisariosMaxim to overthink]] these, but some impulsive connections are bound to occur. If taken far enough, such speculation can overlap with the LiteraryAgentHypothesis. (In fact the LiteraryAgentHypothesis may be the best way out of the paradox: the Tenth Doctor doesn't ''actually'' look like David Tennant any more than Erin Brockovich really looks like Julia Roberts.)

If the actors or their works do not exist, this implies an InSpiteOfANail AlternateUniverse. In a recent and amusing example, actress Jeri Ryan divorced her husband to play Seven of Nine on ''StarTrekVoyager'' (he refused to move to Hollywood with her). The divorce was contentious, and a lot of salacious dirt was spilled. When Jack Ryan ran for the U.S. Senate in 2004, the release of the documents forced him to withdraw, allowing his challenger to win in a landslide against a last-ditch replacement. The landslide victory propelled the challenger, BarackObama, to a position from which he could then launch a campaign for President, and... well, you know the rest. But it probably goes differently in ''Voyager'''s historical database.

Many a show or movie trying to be hyper-realistic do their best to distill this concept to an extent by refusing to cast a CelebrityStar because he or she is not obscure enough and would be too recognisable, as it strains WillingSuspensionOfDisbelief.

Note that, in AnimatedSeries and {{Anime}}, the CelebrityParadox wouldn't be as big of an issue. After all, in this type of medium, the characters wouldn't necessarily resemble the actors who do the voices of them. Additionally, the paradox may be avoided if the work is a PeriodPiece set before the actors were famous. So, for example, no one in ''[[IndianaJones Raiders Of The Lost Ark]]'' can wonder why Indy looks exactly like HarrisonFord because the film is set before Harrison Ford was even born. Perhaps, the paradox may also be avoided in works that take place in [[TheFuture the far future]] -- when the actors are likely to be forgotten.

Playing with this is a form of PostModernism. ActorAllusion can be a form of playing with this. Contrast YourCostumeNeedsWork.

!!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]
* ''LuckyStar'' has quite a bit of this thanks to its numerous modern-day media references to anime, manga, video games, etc. Prime examples include multiple shoutouts to its fellow KyotoAnimation anime ''[[SuzumiyaHaruhi The Melancholy Of Haruhi Suzumiya]]'' and the guest appearances of the character's own seiyuu.
** Probably the prime example of this is in the last episode. [[OccidentalOtaku Patty]] bribes Konata (voiced by [[AyaHirano Hirano Aya]] with a ticket to a live event where she can meet... Hirano Aya.
** Of course there's also an earlier episode where [[AyaHirano Konata]] attends the ''Suzumiya Haruhi no Gekisou'' live concert and sees [[AyaHirano Hirano Aya]] on stage.
** The show also bizarrely folds in on itself in one of the later episodes where Konata, in RippedFromTheHeadlines fashion, finds a plaque that reads "Konata is my wife".
* A case in ''DetectiveConan'' once revolved around the titular character and his friends meeting singer Minami Takayama. Minami happens to do the voice of Conan Edogawa, and their similar voices were pointed out by other characters. The weird part? That story appeared in the original manga.
** Not so weird, considering mangaka Gonsho Aoyama was dating, and then got married to, Minami.
* An episode of ''AkahoriGedouHourRabuge'' has two of the Hokke sisters meeting their own voice actresses and then proceeding to argue about which one of them is better.
* Completely pulled off in ''NogizakaHarukaNoHimitsu'', {{Meido}} Nanami Nanashiro distracts the proud {{Otaku}} Nobunaga Asakura by telling him that seiyuu Kana Ueda is nearby and proceeds to mimic her voice to make Nobunaga 'chase' the seiyuu. Of course, Kana Ueda herself ''is'' the seiyuu of Nanami.
** In the first episode of the second season, Yuuto and Haruka (who's voiced by Mamiko Noto), go to see the voice actress of a ShowWithinAShow. The character she voices heavily resembles Haruka and is also voiced by Noto -- in the show's universe. Essentially resulting in Haruka going to meet her own voice actress.
* In ''TransformersCybertron'' there is no "Transformers" cartoon but Transformers have become an urban legend. Somehow.
** Because in the Japanese version, "Galaxy Force", there have been TF's hidden on Earth for centuries, such as Live Convoy. In the American version, they halfheartedly tied it in with Energon and Armada as the "Unicron Trilogy", and thus TF's had both been hidden on Earth for centuries like Evac (Live Convoy renamed), ''and'' they have visited Earth twice in the past 20-30 years or so. No real CelebrityParadox here.
* In ''WelcomeToTheNHK'', the titular conspiracy shares its acronym with a real-world broadcasting company, which doesn't seem to exist in the anime. Also, ShowWithinAShow ''Puru Puru Pururin'' has a real website complete with show time listings, but the times and channels correspond to when ''WelcomeToTheNHK'' airs.
** Er, the point of the acronym is that the protagonist thinks that the broadcasting company is a central part of the conspiracy to isolate otakus, at least in the original novel. It's not made as clear in the anime, presumably to avoid uncomfortable legal issues.
* Done several times in the original ''AstroBoy'' manga. Once, when showing a theme park full of fictional creatures, a villain disparagingly refers to "Those creepy gourd creatures Tezuka draws.", indicating that Osamu Tezuka, the creator of AstroBoy, ''does'' exist in their universe. Another time, a bad guy taunts the Professor by saying, "And what have you done with Astro? You've just made a stupid show of him for TV!"
* ''{{Kampfer}}'' seems to love this for some weird reason. Counting off, we've got YuiHorie, YukariTamura, and NanaMizuki all mentioned when their own characters were arguing. Surprisingly, Natsuru (voiced by MarinaInoue) has yet to be brought up by anyone.
[[/folder]]

[[folder: Comic Books ]]
* Like everything else they do, comic books (particularly those from Marvel and DC) tend to be pretty up and down when it comes to this. One storyline will explicitly state that the other version of heroes are simply limited to fictional comics, another will confirm that they all coexist with the same world, and in another, {{Alternate Universe}}s come into play. All in all, [[BellisariosMaxim most writers try not to stress over this too much]], as more often than not, the main objective is to either have [[LetsYouAndHimFight two heroes duke it out in a prize fight]] or simply deliver some cheap shot.
** I think it's widely established that TheDCU and MarvelUniverse exist in the same... Multiverse? Megaverse? Adjacent multiverses? Same something. They met on several occasions, and the universes even merged for a while in the early 90s.
** DC, prior to 1986, did this using Earth-2 and claiming that the Earth-1 characters had comics about the Earth-2 characters but not about themselves. This explanation worked for characters like the Flash, but wouldn't make sense for someone like Superman, where both versions had the same secret identity.
** However, at least in the MarvelUniverse, there is {{Canon}} evidence from comics such as ''She-Hulk'' and ''The FantasticFour'' that the exploits of the (in-universe) real live heroes are actually recorded in comics and sold to the general public. These comics (in the ''She-Hulk'' comics) are then used as evidence by lawyers defending and prosecuting super heroes and super villains. And, at least once, to save the world when all the characters had forgotten some hugely important fact or MacGuffin which they found out about by reading the comics. One wonders, though, if the comics published in-universe are the same as the RealLife ones, and the references to comics are infinitely recursive. But then one's head starts hurting.
*** Marvel actually ''released'' a set of in-universe comics during a FifthWeekEvent in 2000. These were titled "Marvel[[color:red:s]] Comics" and how similar they were to the "real" superheroes varied -- the Fantastic Four licensed their comic officially and appeared in their real identities, but since nobody knows who Daredevil or Spider-Man are, the in-universe comic fabricated origins for them.
* ''Superman'' #411 estalbished that the Julius Schwartz of Earth-1 went bankrupt after he unveiled Ultra-Man, Madame Miracle, Night Wizard, and Jet Jordan only to see the emergence of the Earth-1 Superman (as Superboy), the Batman, Wonder Woman, and the Flash (whether they meant the publication of Jay Garrick's adventures on Earth-1 or the emergence of Barry Allen remains unclear -- also, other stories established that the Shadow actually existed as part of Earth-1's past, so Night Wizard would have already seemed a tad redundant). Possibly, Madame Miracle explains how Wonder Woman seemingly appeared on the copy of ''All-Star Comics'' #37 that Barry Allen had in ''Flash'' #137; otherwise people on Earth-1 would have felt astonished when the Earth-1 Wonder Woman left Paradise Island to enter Man's World. (On a related note, no word ever appeared on what the people of Midway City, Michigan felt when someone dressed in a virtually identical costume to Hawkman emerged, and a museum curator named Carter Hall moved into town.) While the Earth-1 Julius Schwartz seemingly appeared as a gainfully employed staff member of the Earth-1 DC Comics in the ''Titans Crisis'' crossover, the ''Teen Titans Index'' #5 notes that this represented a different bald, glasses wearing-staff member.
** Similarly, in the UltimateMarvel universe, one issue of ''UltimateSpiderMan'' involved Spidey's exploits being filmed by Sam Raimi to save money on CGI for a blockbuster movie starring Tobey Maguire.
** When Ultimate Spidey went to Raimi to ask him to stop, they just filmed him some more, making Raimi look like a gigantic tool. Very odd.
** Maybe that was [[TakeThat revenge]] on Raimi for ''Spider-Man 3''.
*** Marvel did another joke on this in ''Spider-Girl''; Mary Jane comments that Reilly Tyne (son of Spider-Man's clone Ben Reilly) looks sort of like like Peter; Pete, on the other hand, thinks he looks more like Tobey Maguire.
**** {{Deadpool}}, meanwhile, has mentioned on more than one occasion that he's seen the Spider-Man movies and knows that it's "doe-eyed Tobey Maguire" underneath the mask. But then, he is Deadpool, so maybe [[NoFourthWall he has seen the movie on the other side of the fourth wall]] or something.
**** {{Deadpool}} Himself says in one issue that he looks like "Ryan Reynolds mixed with a Shar-Pei". No sign of the Shar-Pei, but who else would get the role when the live-action movie came out?
** Subverted in ''Superman: Secret Identity'', where there are no superheroes, but ''Superman'' comics do exist -- they're, in fact, the reason Mr. and Mrs. Kent decided to name their perfectly human boy Clark. Then, after being constantly bullied about his nonexistent superpowers, he actually gets them, and the rest of the plot explores the differences between comics and "reality".
*** This is also the origin of Super[[strike:boy]]man-Prime. His psychopathic behaviour in pursuit of Silver Age values can be at least partly explained by the fact he still thinks of these people as fictional characters.
** A GoldenAge ''{{Superman}}'' story had Clark taking Lois to the movies... where a Fleischer Brothers ''Superman'' cartoon was showing before the main feature. HilarityEnsues as Clark goes to great lengths to ensure that Lois is distracted every time his on-screen counterpart changes identities. The story ends with Clark and his on-screen counterpart winking at each other, even as he wonders who the Fleischer Brothers ''are'' and how they found out all they did.
* While maybe not textbook, ''{{Watchmen}}'' played with this a little bit. Since superheroes exist, they became commonplace and nobody bought superhero comics anymore. To fill the publication vacuum, comics starring pirates became popular.
** The ''Top Ten'' universe plays around with this. With so many superheros, comics about mundane people, such as accountants, are popular.
** ''{{Runaways}}'' mentions TheDCU a few times, but it's implied they only exist as TV shows.
*** If you're referring to the Smallville reference, I'm not so sure. It seems to me that as teenagers around 2004 or so, that would just be the version of Superman they might be most familiar with.
*** It also features references to the Batman series from the 60 and the later live action films.
* ''AstroCity'' plays with this as well. Comic book publishers can either publish stories of fictional characters like {{Batman}}, or secure licensing rights and publish the exploits of real superheroes. Since the heroes are real, authors and publishers are vulnerable to libel laws, and comics are required to adhere to known facts and events.
** The story "Where the Action Is" details a comic publisher who publishes embellished exploits of "real life" heroes and villains, with dangerous results; the heroine Nightingale threatens him when he suggests she and her partner are lesbians, while the villain Glowworm almost kills him when he's portrayed as a racist (Glowworm has a radioactive sheen -- underneath it, as he puts it, "You know what color I ''used'' to be?"). After the last threat, he decides to start a line of "cosmic" (alien/otherworldy) heroes and villains, since they are too [[AscendToAHigherPlaneOfExistence above mortal concerns]] to register complaints. [[spoiler:The building gets vaporized one morning several months later.]]
* In his DonaldDuck comic stories, DonRosa prefers to think of Mickey Mouse and other non-Duck cartoon characters as the fictional characters within the fiction, and the Duck characters as the "real" people. This becomes weird when you take into account that Donald was also Mickey's co-star in animation.
** DuckTales comics also exist inside his universe. He's mentioned that he likes to think of them as unlicensed fabricated adventures based on the colourful character of the city's biggest celebrity, Scrooge [=McDuck=], and would like to make a comic about him facing the copyright issues involved to prevent the comic's sale, but Disney hasn't at least yet relented to allowing its major animated series to be treated like a pirate release, even inside a comic.
*In some {{Archie Comics}}, the gang can be seen reading their own comic book. Why they aren't disturbed by seeing themselves and their stories in print is beyond me.
[[/folder]]

[[folder: Fan Fiction ]]
* In ''ShinjiAndWarhammer40K'', one of the author's notes points out that it's odd there are still EmotionlessGirl anime in a world without ''NeonGenesisEvangelion'' to popularize the trope.
** [[DidNotDoTheResearch You ''do'' know what a paradox is, right? It doesn't mean slightly improbable, to give a hint.]]
*** If someone had killed Walt Disney before he started making cartoons, you'd expect the world of WesternAnimation to be very different. If Henry Ford had been run over by a horse, cars would be different. Without ''EVA'', subsequent animes with characters based on Rei wouldn't exist or would be very different, even ''if'' someone else made a popular anime with an EmotionlessGirl. Several series with characters based on the EG trope that exist in our world are also present in the fanfic's world.
[[/folder]]

[[folder: Film ]]
*Completely and utterly justified in ''TheGrapesOfWrath'' film. In the book, the main character was said to look exactly like Henry Fonda, so guess who played him in the film? That's right, Henry Fonda.
** Joseph Heller tried to pull the exact same trick in ''{{Catch 22}}''. Maj. Major Major Major looks identical to Henry Fonda, and is often mistaken for him by other characters. Heller admitted that he wanted either Henry Fonda or someone who looked absolutely nothing like Henry Fonda to play him in the movie; he ended up getting his latter wish when Bob Newhart was cast as Major.
** The exact opposite happened with the ''{{Constantine}}'' [[InNameOnly adaptation]]. John Constantine is stated to look exactly like Sting in the comics, so [[WallBanger naturally]], they had KeanuReeves play him in the film.
*** Although to be fair by the time of the Constantine film Sting was in his early fifties while John Constantine seems to have been time-frozen with Sting's haircut in the early eighties.
**** Then again, since Vertigo Constantine ages in real time, the character is in his fifties now. Though the story arc adapted for the film happened in the '80s. Either way, they clearly [[InNameOnly weren't going for fidelity to the source]] here.
* In the Schwarzenegger flick ''LastActionHero'', the real world contains the same actors and movies that we know in reality. In the [[ShowWithinAShow Film Within A Film]] ''Jack Slater IV'', there is ''still'' a ''{{Terminator}}'' movie -- but it stars Sylvester Stallone. Furthermore, when Slater is in the real world, he runs into Arnold, who mistakes him for a look-alike.
* There's a memorable LampshadeHanging of this trope in the otherwise forgettable film ''Stakeout'': To pass the time while on stakeout, Emilio Estevez and Richard Dreyfuss's characters are playing a guessing game where they cite memorable lines of dialogue and quiz the other as to what movie it's from. Emilio Estevez's character, in a [[LargeHam hammish]] way, recounts the line: "''This'' was not a ''boating accident!''" Dreyfuss, after a moment's pause, replies "I don't know." The line is from the film ''Jaws'', spoken by Matt Hooper -- a character played ''by'' Richard Dreyfuss.
* Possibly the earliest example after ''Arsenic and Old Lace'' : In the 1940 film ''His Girl Friday'', a character played by Ralph Bellamy is described as looking a lot like "that actor, Ralph Bellamy."
** Anoter would be Cary Grant making a reference to a friend of his named "Archie Leach". It's Cary's real name.
* ''TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension'' averts this by treating the movie as a documentary of the real life of Buckaroo Banzai, who also has his life's stories printed in comic book form and uses his fan club as a spy network.
* ''Ocean's Twelve'' had Tess Ocean, played by Julia Roberts, infiltrating a museum by exploiting the fact that she looks like Julia Roberts. And then she has to interact with several other celebrities like Bruce Willis who know Julia Roberts. The fact that Danny Ocean couldn't do the same implies that this is a case of OneShotRevisionism.
** The original ''OceansEleven'', starring the Rat Pack, also played with this. In the final shot, the characters played by Frank Sinatra, Dean Martin, Sammy Davis Jr., Joey Bishop, and Peter Lawford walk past the marquee of the Sands hotel. The marquee advertises the Sands' featured entertainers: Frank Sinatra, Dean Martin, Sammy Davis Jr., Joey Bishop, and Peter Lawford. Despite this, Dean Martin plays a completely different singer named Sam Harmon, who does a few shows in Vegas without anyone mentioning he looks familliar.
** The remade ''Ocean's Eleven'' flirted with this in one of the earliest scenes, when Danny and Rusty walk out of the club where they've been teaching celebrities to play poker. It's very odd to see Topher Grace and Joshua Jackson get mobbed by squealing fans, while George Clooney and Brad Pitt stroll by unnoticed.
* Similar to the Julia Roberts example above: as a running gag in ''Cannonball Run'', eccentric competitor Seymour Goldfarb Jr. obsessively impersonates Roger Moore, both to attract women and to justify his use of 007-style gadgets to get an edge in the race. Goldfarb, naturally, is played by Roger Moore ... who sends up both his actual celebrity status ''and'' his past in-character behavior as James Bond.
* In ''BackToTheFuture'', Huey Lewis makes a cameo appearance as an audition judge -- and Marty has a Huey Lewis and The News poster on his bedroom wall. The Cafe '80s scene in ''Part II'' shows brief clips of ''FamilyTies'' and ''{{Taxi}}'' -- featuring Michael J. Fox and Christopher Lloyd, respectively. However, whether the actors were featured in the shows of the universe is subject to debate.
** Furthermore, in an episode of ''BackToTheFutureTheAnimatedSeries'', Marty sarcastically claims to be Michael J. Fox (who played Marty in the movie trilogy) -- prompting Verne to comment that there is a similarity in appearance.
* In ''LoveActually'', Liam Neeson makes several jokes about having Claudia Schiffer appear and start a relationship with him. Towards the end of the movie he meets a woman named Carol...played by Claudia Schiffer.
* In ''[[{{ptitle36fwwzhk}} Looney Tunes: Back In Action]]'', DJ Drake says to Daffy: "Have you seen those ''[[TheMummyTrilogy Mummy]]'' movies? I was in them more than Brendan Fraser was!". At the end of the movie, Drake runs into the real Fraser (obviously played by Fraser as well) then punches him in the face for acting like a dick.
* ''[[RockyAndBullwinkle Boris and Natasha]]'' had the famous bad guy couple pretending to defect in the early Post-Cold War world, where they become instant celebrities. One scene has them fleeing a party just as the host says "But Sally Kellerman wanted to meet you!" Natasha is, of course, played by Kellerman.
* The novel ''Bridget Jones' Diary'' is based in part on the plot of ''PrideAndPrejudice'' -- the love interest is named Mark Darcy, and the title character is obsessed with Colin Firth's portrayal of the original Mr. Darcy in the 1995 BBC adaptation of the Jane Austen novel. In the film, ''Pride & Prejudice'' isn't mentioned, but Mark Darcy is played by... Colin Firth.
** Bridget interviews Colin Firth in the sequel, ''Bridget Jones: The Edge of Reason''. This was filmed for TheFilmOfTheBook but ended up being a DeletedScene.
* In the novelization of the first SpiderMan film, Mary Jane has seen the movie ''InterviewWithTheVampire'' and was creeped out by the little girl who played Claudia. Guess who played both of them.
* Pretty much averted in Kevin Smith's ''[[TheViewAskewniverse Jay and Silent Bob Strike Back]],'' where Ben Affleck plays the character of Holden [=McNeil=], the same character as in the earlier ''Chasing Amy''. The movie's central conflict is that a movie is being made about the titular characters and they aren't being paid for it, so they start discussing who's going to star in the movie. Ben Affleck's character comments that, because it's Miramax, it's probably going to be Ben Affleck and Matt Damon. Later on, Affleck shows up again, as himself, shooting ''Good Will Hunting 2: Hunting Season'' with Damon.
** It gets better when Jay and Holden talk about how they hate ''Good Will Hunting,'' which Affleck starred in and co-wrote, and Holden citing that Affleck was the bomb in ''Phantoms.''
** Come to think of it, before Affleck and Damon do their part in ''Hunting 2'' Damon mentions that Affleck talked him into ''Dogma.'' Jay and Silent Bob were in ''Dogma,'' as main characters.
*** For the hat trick, at the very end, two characters leaving a theater say that the movie they saw was "Better than ''{{Mallrats}}''," (which one of them was in) but that ''Chasing Amy,'' the movie the other one was in, would never work as a movie.
** Even better is the DVD documentary where the writers talk about how for a while, they were actually considering having different actors play that universe's Ben Affleck and Matt Damon. They even considered the Wayans Brothers for it. Sadly, they chose in the end to just keep the originals.
* The 2006 film of ''CasinoRoyale'' faithfully reproduces a scene from the original novel where JamesBond orders a very specific kind of martini -- three parts Gordon's gin, one part vodka, 1/2 part Lillet. In the real world, this drink, called a "Vesper" after Bond's love interest in the novel, has become well-known enough to have an entry on ThatOtherWiki, and a bartender presumably wouldn't need to be instructed on how to make one -- of course, in the movieverse, the James Bond novels don't exist and so presumably nobody has ever heard of a Vesper martini.
** Actually, This Troper has to teach quite a few bartenders how to make that drink. I live in a major American coastal city, but some bartenders, even from very upscale establishments, give me a very very blank look when I ask for a Vesper.
** This is also lampshaded in the movie, when Bond mulls over what to name the newly invented drink until telling Vesper flat-out that he's naming it after her.
*** Not really a lampshading -- again, that's a reproduction of a scene from the original novel, and was how the drink got famous! (Ian Fleming, or a friend of his, invented it!)
** James Bond had been said by Ian Fleming to look like Hoagy Carmichael and David Niven. The latter got to play him in ThatOtherCasinoRoyale.
* ''BlazingSaddles''
** The FourthWall-shattering climax of -- just watch it.
*** Includes a scene where Taggart says "I'm working for Mel Brooks!" (writer/director), who also appears in the movie.
** Hedley Lamarr -- and later Bart and the Waco Kid -- go to Graumann's Chinese Theatre in Hollywood to watch the movie they're in. Mel Brooks seems to be a bit fond of this device.
* Similarly, in ''{{Spaceballs}}'' the villains are able to track down the heroes' location by popping in a ''{{Spaceballs}}'' VHS. [[http://www.youtube.com/watch?v=zvd3kaupZ60 No really]].
** That's more of a fourth-wall break rather than a confirmation that ''Spaceballs'' actually exists in-universe. They do something similar in ''RobinHoodMenInTights'' where they pull out the film script to see what happens next.
*** The "character pulling the script" gag is used twice by the Genie in ''{{Disney/Aladdin}}''.
* The ''{{Scream}}'' franchise made it big in part because it was a horror movie that acknowledged that people will know about horror movies and thus display at least some GenreSavvy, compared to all the horror films that take place in universes where apparently [[GenreBlindness no such things exist]].
**''Scream 2'' took it further with the (fictional) film ''Stab'', which was based on the events of ''Scream'', scenes from ''Stab'' having Heather Graham and Luke Wilson playing the the characters played by Drew Barrymore and Skeet Ulrich. Courtney Cox's character also mentions David Schwimmer and Jennifer Aniston.
** In ''Scream'', Neve Campbell's character Sidney jokes that if they did make a movie of the Woodsboro murders, Tori Spelling would probably play her. In ''Scream 2'' with ''Stab''... cue "Sidney" being played by Tori Spelling.
* Like most rapper-actors, Method Man can most often be found portraying gang members and fictional rappers in his numerous television/film roles. Wonder if any of them listen to Wu Tang.
** In ''The Wackness'' he plays a drug supplier who gives the main character a copy of Biggie's ''Ready to Die'' '''AN ALBUM HE WAS FEATURED ON!'''
** Even more confusingly, RZA has a role as a detective in ''American Gangster''. At one point, the Wu-Tang tattoo on his arm is clearly visible. Note that the film takes place ''in the 1970s''.
* In the movie ''FearAndLoathingInLasVegas'', while walking through a rock club in a flashback within the film [[spoiler:Johnny Depp as Thompson narrates, "There I was...," suddenly stopping when he spots the ''real'' Dr Hunter S. Thompson in the shot, exclaiming, "Mother of God, there I am! Holy fuck..."]].
* In ''{{Crank}}: High Voltage'' a witness is asked to describe Jason Statham's character, Chev Chelios, and refers to him as "like the man from those Transporter movies." Guess who plays the Transporter.
* ''VoodooMan'' starring Bela Legosi, features at the end a reporter laying out the events that have transpired, suggesting that it could be made into a movie with Bela Legosi.
* ''DanceFlick'' made by the Wayans Brothers features a scene were the acting coach explains how the only roles for black actors in Hollywood go to the Wayans Brothers.
* Odd example in ''The Life Aquatic With Steve Zissou'': Zissou is a clear parody of Jacques Cousteau, right down to the uniforms...yet at one point he makes an offhand reference to "Cousteau and his cronies". No one comments on the resemblance between the two crews.
* In ''The Freshman'', Matthew Broderick's character tells Marlon Brando's, "You know, you look an awful lot like the Godfather." The problem was that Marlon Brando tripled his body mass between movies, so he didn't really look that much like TheGodfather.
* ''Hook'' handles this quite nicely. J.M. Barrie's play ''PeterPan'' does exist, as do all of its adaptations like the Disney film. It was based on a true story that Wendy told him. Hence, everyone knows about Peter Pan but thinks he's a fictional character, including Peter himself after he grows up, so he's understandably reluctant to believe it when he finds out.
* Subverted in ''{{Airplane}}!'', in which Kareem Abdul-Jabbar, then a basketball player for the Los Angeles Lakers, played the co-pilot. A child is brought up to the cockpit, recognizes Kareem, and begins making disparaging comments about his basketball skills; the co-pilot at first denies that he is Kareem, but eventually defends himself.
** A bit of a sly nod to that particular scene occurred in MTV's first Rock and Jock Basketball game, in which the show opens with Kareem Abdul-Jabbar (coach of one of the teams) being approached by a fan who mistakes him for Roger Murdoch, famous airline pilot. The scene plays out almost identically, except with roles reversed.
** Furthermore, when the co-pilot is removed after falling ill, he is clearly wearing goggles and a Lakers uniform, as if he was ready to hit the court the second the scene wrapped.
** Another case was when Ted was in the hospital. One of the patients thinks he's Ethel Merman. Guess who plays him.
* In the world of the [[DisContinuity forgettable]] 1998 ''{{Godzilla}}'' film, there was no such thing as a Godzilla movie. The titular monster was named after a supposed mythical Japanese sea creature called Gojira (Godzilla's name in Japan) whose name gets mispronounced.
** The "supposedly mythical" monster may have been ''the'' Gojira/Godzilla. In ''Godzilla, Mothra, King Ghidorah'', the "Godzilla" attack in New York was mentioned and quickly dismissed as not actually being Godzilla. This "Godzilla In Name Only" appears in a later movie, CG and all, under the official name "Zilla" ...And gets his ass handed to him in less than five seconds.
* In ''Gremlins 2'' this was done several times -- the Gremlins attack a movie critic who is giving a negative review of the first movie, and mid-way through the movie, the Gremlins appear to take over the cinema's movie projecter room, using it to make shadow puppets and show black and white porn. They are only stopped when an usher gets Hulk Hogan, who is in the audience at the time, to threaten to introduce the Gremlins to "The Hulkster".
** The movie critic in question is real-life critic Leonard Maltin. In his ''Movie and Video Guide'', Maltin notes that ''Gremlins 2'' contains "gratuitous celebrity cameos."
* Peter Jackson's remake of ''KingKong'' is apparently set at the same time that Merian C. Cooper is directing [[KingKong a film]] for RKO Studios starring Fay Wray.
** It needn't be ''KingKong'', since at that time, Cooper was also producing another RKO movie with Fay Wray, ''The Most Dangerous Game''.
* Played with in the ''{{Hellboy}}'' film, which is based on a comics series: the titular demon is actually a pretty popular myth, on par with stuff like Yeti and Bigfoot (though perhaps slightly more believed), and has comics based on him, prompting a supporting character, upon meeting him, to be surprised that his comics hero from childhood is real, and for Hellboy himself to comment that he dislikes the comics as they get his eyes wrong.
**On the other side of the Canon, the graphic novel ''Lobster Johnson: The Iron Prometheus'' has articles detailing the title character's in-world media appearances. One of the articles mentions that interest in remaking the [[AdaptationDecay largely inexplicable]] Mexican Lobster Johnson movies had been expressed by "acclaimed Mexican director Guillermo Del Toro".
** Referenced in ''AbeKroenen'', where Kroenen mentions that the Hellboy clone had gotten himself a job as a Hellboy impersonator. Abe asks if the clone has a partner impersonating him and Kroenen mentions that there is an Abe impersonator "but she's not very good at it".
* Robby the Robot in ''ForbiddenPlanet'' was the [=R2D2=] or [=C3PO=] of its day and has been used almost like a live action [[AnimatedActors Animated Actor]], making this one of the few times this trope applies to a nonhuman character. The Blu-Ray/HD home video version of the movie includes a ''ThinMan'' episode and a movie ''The Invisible Boy'' where Robby appears, under his own name; needless to say, characters are astonished by the robot but never associate it with a movie.
* At the end of the ClintEastwood movie ''Any Which Way You Can'', the cast is musing over their drinks in a bar, where the lounge singer is singing the song, "You're Just a Coca-Cola Cowboy," with the line "You've got a sexist smile and Robert Redford hair." The ''actual'' line in the song is "You've got an Eastwood smile and Robert Redford hair."
* ''StarTrekIVTheVoyageHome'' was played largely as a FishOutOfTemporalWater comedy in which the ''Enterprise'' crew goes back to ThePresentDay (1986). You have to wonder why they never meet anyone who has heard of ''Star Trek''.
** The same could be asked of the ''StarTrekVoyager'' two-parter ''Future's End'' where the crew of Voyager find themselves in the mid-90s (especially confusing at they appear at a time where the Eugenics War should be raging, but this apparently has had no effect on the people of California).
*** A few latter Trek novels indicated that the Eugenics Wars -was- all the late twentieth-century conflicts. The real purpose of those wars were not quite obvious.
* ''FinalDestination''. It's VeryLooselyBasedOnATrueStory. Nobody remarks about the extremely similar 747 crash four years earlier.
* A particularly complex example is in ''Man on the Moon'', a BioPic of Andy Kaufman. Danny [=DeVito=] plays Kaufman's agent George Shapiro. [=DeVito=] was also a producer of the film, and explained in a making-of short that he had wanted to play Shapiro from the beginning -- not realizing that this paradox would be created because he had played Louie [=DePalma=] on ''Taxi'', which was Kaufman's biggest mainstream success and thus had to be brought up in the film. The solution was to write out Louie (and thus the real [=DeVito=]) from the ''Taxi''-related scenes (though, in an early script draft, there was going to be an aside referencing the character and thus the paradox as an in-joke). At least one critic admitted [[Main/FridgeLogic he hadn't noticed Louie's absence until later]], perhaps in part because most of the other ''Taxi'' cast members appeared as themselves.
** Tony Clifton's character on ''{{Taxi}}'' was supposed to be Louie's brother.
** [=DeVito=]'s characters in the movie and ''Taxi'' were visually and dramatically distinct enough that he arguably could have still appeared as himself/Louie. The mustache alone is all the license you need.
* All the remakes of ''[=~Miracle on 34th Street~=]'' (there are no less than four of them, five if you count the Broadway musical) are presumably set in a world where the 1947 classic doesn't exist.
* The first scene of ''Tango and Cash'' has Tango saying "[[http://www.agonybooth.com/agonizer/Tango___Cash_1989.aspx Rambo is a pussy.]]" Guess who plays Tango.
* ''Adaptation.'', starring MerylStreep and Nicolas Cage, is about a playwright's struggles to adapt Orlean's book ''The Orchid Thief'' to film. Streep plays the film version of Orlean (who really existed, and really did write ''The Orchid Thief''), with Cage starring as screenwriter Charlie Kaufman. Guess who wrote the actual film? Charlie Kaufman.
** And then you realize that the screenplay being written by the film's Charlie Kaufman [[spoiler: is ''the screenplay for the actual film you are watching.'']]
* Used to effect in ''FightClub'': There's a scene where Edward Norton and Helena Bonham Carter are talking outside a movie theatre, after Norton has discovered that Brad Pitt's character [[spoiler: is his split personality]]. The movie playing is ''Seven Years in Tibet'', a subtle reminder that Pitt's character is invisibly present in this scene.
* In the 2007 ''StTrinians'' movie, Colin Firth plays the Minister for Education -- which means that we get jokes about a dog named "Mr. Darcy" and a reference to ''The Girl With A Pearl Earring''.
**Additionally, Colin Firth himself gets a mention.
* In the world of the ''{{Batman}}'' films it can be funny when you think about that Bruce Wayne himself is a world-renowned personality. How often does Bruce Wayne get told He looks like Adam West/Michael Keaton/Val Kilmer/George Clooney/Christian Bale and vice-versa with the actor?
* In ''Shrink'', RobinWilliams plays actor Jake Holden. Another character in the film is a fan of classic movies, and in one scene she's watching ''TheGraduate'', so we know Dustin Hoffman exists as himself in the film. The question is: did Jake Holden star alongside him in ''{{Hook}}'' in this universe? Was he also the star of ''GoodMorningVietnam'', ''MrsDoubtfire'', and many others? He must have been, because no one comments on how he looks just like Robin Williams.
* [[spoiler: Bill Murray]] cameos as himself in ''Zombieland''. He doesn't seem to notice how much Tallahassee looks like [[spoiler: the guy he starred with in ''Kingpin''.]]

[[folder: Literature ]]

* Averted and played with extensively in the ''ThursdayNext'' series -- almost inevitable, since the series is about the [=BookWorld=] and the title character can travel in and out of works of literature. In the most recent installment, Thurs is forced to work with two alternate versions of herself from "fictionalized" ''book'' versions of her adventures.
** The ''ThursdayNext'' books take this much, much farther than any sane person could go. There are many "meta" levels -- for example, there's the real world, the "real world" of the ''ThursdayNext'' novel, fiction that exists in the ''ThursdayNext'' world (which is largely unchanged from ours), how the fictional characters act ''outside'' their novels, etc...
** It gets even ''more'' confusing because the ''ThursdayNext'' novels as shown in the fifth ''ThursdayNext'' book are actually nothing like the real-world novels; the rights were sold and the plot and characterization was thrown out the window. [[spoiler:At the very end of the fifth book, apparently one of the fictionalized Thursdays begins "rewriting" the fictional ''ThursdayNext'' books and it looks like they'll end up identical to the real-world versions. Confused yet?]]
*** At one point, in Thursday's real world, she freaks out a little, because people are reading her! Then she realizes she is being dumb. After all, it's the real world. Nobody is reading her.
* In the sequel to the novel ''ForrestGump,'' titled ''Gump and Co.'', Forrest is inserted into events from the 80s and 90s. As such, he gets to meet famous people from that time. One such celebrity whom Forrest gets to meet is Tom Hanks, the actor who played him in the film. In fact, the movie is mentioned several times throughout the book -- the first book exists in that world as Forrest's autobiography, and he's rather upset throughout the second that the film got almost everything wrong. "Don't ever let anybody make a movie out of your life" are practically ArcWords.
* Arguably, this can occur in literature when characters are based around real people. For example, in Anthony Trollope's ''Palliser'' series, there are characters clearly based on real people like Gladstone and Disraeli, but on at least one occasion, the real people were referenced. Another example, is the problem of how to deal with Arthur Conan Doyle in a universe where SherlockHolmes is a real person. A common idea is making him a [[LiteraryAgentHypothesis literary agent]], but if that was true, he likely wouldn't be as wealthy and famous in that universe as in reality.
* The ''HarryPotter'' [[{{Defictionalization}} spin-off books]] ''Fantastic Beasts and Where to Find Them'' and ''Quidditch Through the Ages'' each begins with an introduction purportedly written by Albus Dumbledore in which he describes how proceeds from the book will go to a fund set up in Harry Potter's name by Comic Relief UK and JKRowling. This, of course, raises the question of how exactly Rowling can exist within the ''Harry Potter'' universe.
** Fyre's ''[[http://www.tthfanfic.org/story.php?no=394 The Eighth Weasley]]'' -- a HarryPotter crossover FanFic set after Voldemort's defeat -- explicitly states that the Harry Potter books exist alongside the Wizarding World (to the consternation of the latter), and subtly hints that "JK Rowling" is merely a pen name behind which is hiding Hermione.
** In [[http://www.fanfiction.net/s/3728284/1/In_the_Words_of_Ginevra_Molly_Potter this fanfic]], JK Rowling is a witch who wrote Harry's biography and then marketed it to Muggles as fiction. She actually turns up at Slughorn's Christmas party.
** And in two {{Dangerverse}} [[AlternateUniverse AUs]], it's Sirius writing an alternate ''future'' which had the books slowly released to the muggles starting on the day the Wizards got ''Deathly Hallows''.
** A fanfic played with this by having Cho Chang audition for the role of Cho Chang in the ''Harry Potter'' movies. She was rejected -- she didn't understand the character's motivations.
*** Do you have the link? I'd love to read that
* In one ''TheDarkTower'' book (''The Waste Lands'') Eddie Dean compares a haunted house the characters escaped to the one in Kubrick's ''TheShining''.
** Considering the fact that Stephen King himself appears in later books in the series, and is basically told by the main characters that he has to write their story, it seems a safe bet that Celebrity Paradox isn't strictly at work here. In their universe (which is also our universe, but also not -- the whole thing is crazy metaphysical and twisted), Stephen King exists, and has written every single book we know him to have written -- and the fact that nearly everything he's written relates back to the very real world of the Dark Tower in some way is caused by the fact that it was his destiny to write about those very real events, even if everyone (including him) thought he was writing fiction.
** King infamously believes that the movie is different enough from his original work for it to be considered its own work. Presumably Kubrick made the movie in Eddie's world without the source material.
*** Considering his opinions on the subject, if you asked Stephen King, he might suggest that Kubrick made the movie in OUR world without the source material as well.
** King also referred to ''The Shining'' movie in ''The Tommyknockers''.
** And ''Carrie'' in ''The Dead Zone''.
* Literary example: Characters in some of Douglas Coupland's books have read his other books.
** It gets even more entertaining. In [=JPod=], beyond characters referencing Douglas Coupland's books as if they existed in the [=JPod=] universe, Coupland himself appears as himself, first sitting beside the main character on a flight to China, then a few other times, before finally becoming, in a way, the antagonist of the story for the main character (as himself, not an omnipotent author figure).
* Disputed in the CthulhuMythos: orthodox fans (as well as the game CallOfCthulhu) assume that Howard P. Lovecraft is absent from this universe, but in a move that would be controversial in hindsight, August Derleth made Lovecraft a character in the Mythos. Fan consensus dismisses Derleth's idea.
** Lovecraft does show up as a historical background character in the partly Mythos-inspired WhateleyUniverse; his stories are acknowledged as fictionalized accounts of real in-universe events, at least some of which he was personally involved in.
** In a Hellboy/Batman/Starman team-up comic, a group of Nazis try to summon a Great Old One. When Starman says "Old One as in Lovecraft?" Hellboy responds "Hey, Lovecraft knew stuff."
* In ''3001: The Final Odyssey'', Poole recalls an old sci-fi author who said "[[ClarkesThirdLaw Any sufficiently advanced technology is indistinguishable from magic]]".
* There is a ''StarTrek: The Next Generation''/''X-men'' crossover novel written that has, Picard meeting Xavier. The resemblance they have to each other is noted. It was written before the X-men movies.
* The Virgil Tibbs series by John Ball (which began with ''In the Heat of the Night'') used a variant of the literary agent hypothesis. In ''The Great Detectives'', edited by Otto Penzler, in which various creators of detective series contributed short articles on their creations (e.g. Chester Gould on Dick Tracy, Walter Gibson on the Shadow, etc.), John Ball took the literary agent hypothesis for his article on Virgil Tibbs. He writes "Ms. Diane Stone, secretary to Chief Robert McGowan of the Pasadena Police Department, was on the phone. "The chief has approved the release to you of the details concerning the Morales muder" she told me. He has authorized you to go ahead with it at any time, if you want to". Of course I wanted to: the unraveling of the case via the patient, intelligent investigation work of the department in general, and Virgil Tibbs in particular, would need no embellishment in the telling. As I always do in such instances, I called Virgil and suggested a meeting. Two nights later we sat down to dine together in one of Pasadena's very fine restaurants........By the time that the main course had been put down in front of us we had gone over the Morales case in detail and Virgil had filled me in on several points which had not previously been made public. As always, I agreed to publish nothing until the department had read the manuscript and had given it an official approval. This procedure helped to eliminate possible errors and also made sure that I had not unintentionally included information which was still confidential". Later Tibbs says "I have a letter from Otto Penzler" I said. Virgil nodded recogntion. "The co-author with Steinbrunner of The Encyclopedia of Mystery and Detection? I have a copy". "Otto has asked me for a piece about your background. How much may I tell him?". I should insert a footnote here. Virgil Tibbs is basically a quiet, self-effacing man....He has mentioned to me more than once that my accounts of some of his cases have proved somewhat embarrasing to him. However, Chief McGowan feels that these books help explain the police function to the citizenry at large and to show how modern, enlightened police departments function".
* The Parker (featuring a ruthless thief) and Dortmunder (featuring a bumbling thief) series (both Donald Westlake, with the former series under the pen name Richard Stark) present a convoluted case. Namely, the Dortmunder novel ''Jimmy the Kid'' established that, in Dortmunder's world, Parker did not exist, and only represented a fictional creation of that world's counterpart of Donald Westlake. In ''Jimmy the Kid'', Dortmunder uses a novel called ''Child Heist'', by Richard Stark, one of Stark's series of novels about a hard-boiled crook named Parker, as a blueprint for how to run a kidnapping. However, Richard Stark is, in real life, as noted, the pseudonym under which Westlake writes the Parker novels. There wasn't a separate novel called ''Child Heist'' in real life, either. Anyway, the kidnapping falls apart and the kid in question, Jimmy, who's kind of a film buff, goes on to make a movie about his experience. There's a chapter at the end of the novel where Richard Stark and his lawyers are sending each other letters speculating about the possibility of suing the kid for using the plot of ''Child Heist'' in the movie. (The lawyer says no, he can make a movie about his experiences, but Stark can try suing the crooks if he can find them.) This would seem to suggest, that obviously, Dortmunder novels do not exist in Dortmunder's universe, and, as noted, Parker only existed in fiction in Dortmunders' world. However, in the first Dortmunder novel, ''The Hot Rock'', published in 1970, one of the members of Dortmunder's crew, Alan Greenwood, is forced to change his last name after his arrest. We learn in the book's penultimate chapter that he now uses the name Alan Grofield.
*Parker had already worked in several books (starting with 1964's ''The Score'') with a partner thief named Alan Grofield, with Grofield even receiving his own solo series of novels. Since, in our world, the Parker novels circulated widely in prison libraries (actual criminals finding it refreshing that Parker and his men usually evaded capture), we could surmise that Greenwood had read one of the Parker novels and chose the name "Grofield" in honor of them. However, both the Dortmunder and Parker series have done crossovers with the ''Dan Kearney Associates'' novels by Joe Gores.
*The Donald Westlake novel ''Drowned Hopes'' (1990), featuring Dortmunder, shares an entire chapter in common with Gore's DKA novel ''Thirty-two Cadillacs'' (1992). ''Dead Skip'' (1972), the first DKA novel, shared a chapter with ''Plunder Squad'' (1972), a Parker novel by Richard Stark (aka Westlake). This would place DKA, Parker and Dortmunder in one universe. To preserve Jimmy the Kid, one would have to say that the Donald Westlake/Richard Stark of this world (i.e. Dortmunder's universe) must have invented a completely fictional adventure for that novel about Parker. After all, if he only fictionalized actual events (i.e. the kidnapping of a previous child by Parker), he would have no grounds for suing Jimmy. However, if he wrote a novel about a completely fictional event, then he might have thought he could sue. This unfortuneately suggests that he penetrated the anonymity that Parker worked under. However, Parker used multiple aliases and alternate identities (e.g. Charles Willis in ''The Outfit'', Ronald Kasper Matthew Walker in ''The Black Ice Score'', Lynch in ''The Green Eagle Score'', possibly Porter, Walker or Archer; the name Parker itself may serve as just another alias) for tax reporting purposes to launder his money by owning gas stations and parking lots, as well as for other purposes. Perhaps Westlake guessed the truth, surmising from police reports that one man had participated in numerous robberies under various aliases. He may have discerned some of the identities that Parker used but not all of them.
*In the novel ''Psycho II'', Norman Bates flees the asylum when he hears that a film of his murder of Mary Crane has started filming. In the book ''Ed Gein -- Psycho!!'' by Paul A. Woods, the author Robert Bloch stated that ''Psycho II'' takes place in a universe where Alfred Hitchcock never made his film adaptation.

* ''TheCatherineTateShow'' did a sketch for ComicRelief which featured DavidTennant as Lauren Cooper's teacher. She frequently jokes throughout the sketch about how much he resembles [[DoctorWho the Doctor]]. At the end, he zaps her with the [[strike:Sonic Screwdriver]] Tissue Compression Eliminator, turning her into a Rose Tyler action figure.
** And adding onto the confusion, Catherine Tate later played Donna Noble, a companion of the Doctor. Conveniently, Lauren Cooper [[spoiler:was killed off]] before she could watch the show and notice the woman who looks just like her traveling through space with a timelord who looks just like her English teacher.
*** Actually, while Donna Noble hadn't yet become a regular character, she had appeared (played by Tate) in a ''Who'' Christmas special prior to the ''Comic Relief'' sketch.
* The [[BritishTellyTropes British Sit Com]] ''MyFamily'' featured Nick obtaining a toy of Madame Hooch from ''HarryPotter''. He doesn't seem to notice that she resembles his mother a whole lot...
* In season two of ''{{House}},'' the title character gets mocked for some of the shows that are saved on his Tivo. One of them, seen briefly but not mentioned, is ''{{Blackadder}},'' in which HughLaurie played a few major characters twenty years earlier.
** It's possible that only the first series of ''Blackadder'' exists in the House-universe, because it's the only one that Hugh Laurie wasn't in.
** There's [[http://www.fanfiction.net/s/4805399/1/Things_Best_Left_Untouched a strange little fanfic]] where House finds a ''JeevesAndWooster'' DVD...
* ''{{MacGyver}}'' starring lead Richard Dean Anderson, is lightly brought up in the very first episode of ''{{Stargate SG-1}}''.
** ''SG-1'' got even more confusing by having a guest appearance by Dan Castellaneta while ''TheSimpsons'' had a guest appearance by Richard Dean Anderson. In ''SG-1,'' Jack is a fan of ''The Simpsons'', but doesn't seem to recognise Dan, even though they specifically bond over ''The Simpsons''. In ''The Simpsons'', Anderson plays himself.
*** In one episode of ''SG-1'', O'Neill points out that there is another O'Neil "spelled with one L" and that he has no sense of humor. The ''{{Stargate}}'' movie featured a Jack O'Neil (one L) played by Kurt Russell who wasn't nearly as snarky as Richard Dean Anderson's character, although the real reason for this line was for legal issues, as "Jack O'Neil" is the name of a real-life member of the US Airforce.
** The StargateVerse has yet another circular dependency: with ''WorldOfWarcraft''. Dr. Lee is a fan of the game (and curiously claimed to have a level 75 character, which was impossible at the time the episode supposedly took place)... while the Champions' Hall in ''[=WoW=]'' contains [=NPCs=] named after ''SG-1'' characters.
** In another interesting case, Carter tells O'Neill that they can't call the first X-303-class spaceship "Enterprise" in homage to ''StarTrek''. Given that NASA has ''already named a spaceship after the fictional Enterprise'', were this not a television show -- whose creators would certainly be sued by Paramount for their insolence -- there would be absolutely no reason not to name the ship Enterprise. Realistically speaking, it would in fact be a virtual ''certainty''.
*** Although, if we're really overthinking this, they would be unlikely to do so until the current ''USS Enterprise'' was retired, freeing up the name for military use.
** Speaking of ''Star Trek'', one wonders if ''[[StarTrekVoyager Voyager]]'' ever got made in the Stargate verse, and if so, whether anyone's ever told Richard Woolsey that he looks just like the Doctor.
* In the ''DoctorWho'' episode "The Idiot's Lantern", the Doctor refers to Kylie Minogue. Kylie later appeared in the ChristmasEpisode "Voyage of the Damned" playing Astrid Peth. [[spoiler:However she was a [[HumanAliens Human Alien]] who had never been to Earth until that episode and from a race with very fuzzy knowledge of our world, thus she probably wasn't aware of the fact. She only met two people who would recognise her as Kylie; the Doctor, who probably chose not to confuse her by mentioning it and Wilfred Mott, who only talked to her for a few minutes.]] That being said, despite the fact she's very famous in the UK [[http://news.bbc.co.uk/1/hi/wales/south_west/6925054.stm one elderly lady did confuse her for a real waitress during filming]].
** "Spatial genetic multiplicity" was [[LampshadeHanging referenced]] in a later episode. May or may not apply here.
** "The Idiot's Lantern" was written by Mark Gatiss, who also appeared as the villain in "The Lazarus Experiment". Mark Gatiss is one of the leads on ''TheLeagueOfGentlemen'', in which one of his characters claimed that an episode of Tom Baker-era ''Who'' was filmed in the town. Another ''League'' member, Steve Pemberton, also appeared on ''Who'' in "Silence in the Library" and "Forest of the Dead". And Christopher Eccleston once did a guest appearance.
** Also in ''DoctorWho'', the ''HarryPotter'' books exist and have been made into movies. The person playing Barty Crouch Jr. has not been revealed though.
*** Clearly, it's going to be Christopher Eccleston.
*** The Doctor does have a Hogwarts uniform in his cupboard. Perhaps it's him, acting under the assumed name "David Tennant".
*** And Barty Crouch Jr. has a box that is bigger on the inside than on the outside.
*** Perhaps he became a Death Eater because he couldn't handle his father creating the Cybermen?
** Just to further twist the self-reference, an Episode with the 7th Doctor in the original series was set on the day the TV show actually launched, and a voice on the telly is briefly heard to say, "It is now 5:15, and its time for the new science-fiction series Do--" before it is cut off.
*** Does the story provide an explanation on why the good Doctor wasn't in [[JohnFKennedy Dallas]] that day?
**** Who says he's not? It's a time travel show, he could always go there later... or earlier!
**** [[http://www.whoisdoctorwho.co.uk/images/dallas_big.jpg Proof our pal the 9th Doctor was in Dallas that day.]]
** The BigFinish Sixth Doctor audio drama ''Pier Pressure'', set in the 1930s, features a young actor called Billy. References to his films make it quite clear that this is young Billy Hartnell, some thirty years before playing the First Doctor.
**In the episode "Army of Ghosts," ''EastEnders'' exists as a fictional television series. The character of Peggy Mitchell bars a ghost she presumes to be Den Watts from The Queen Vic. In the real ''EastEnders'' Watts was killed by his wife Chrissie, who is played by Tracy-Ann Oberman. Oberman played Yvonne Hartman in "Army of Ghosts."
* RobinWilliams does exist, as himself, in the ''MorkAndMindy'' universe. And Mork is horrified when people think they look alike. This is actually almost believable, until Mindy mentions he's a star of "'''TV''', film, and nightclubs". Maybe Robin Williams was part of the cast of whatever TV show replaced ''Mork And Mindy'' in said universe.
* In an episode of ''Sabrina The Animated Series'', Sabrina questions about "Who needs Melissa Joan Hart's autograph?" Melissa Joan Hart plays both of the aunts in the animated series, and she also played the title character in the earlier live-action series of ''SabrinaTheTeenageWitch''.
* ''MadAboutYou'' exists in the ''{{Seinfeld}}'' universe, but characters from ''Seinfeld'' have appeared on ''MadAboutYou''. Some sort of ''Seinfeld'' series also exists on ''MadAboutYou'', but it's unclear whether the series in question is the one from [[RealLife the real world]], starring real Jerry Seinfeld, or the fictional sitcom ''Jerry'', starring the real Jerry Seinfeld's character portraying a character named Jerry Seinfeld ([[WildMassGuessing who might himself be the real Jerry Seinfeld]]).
** Paul Reiser's ''MadAboutYou'' character, Paul Buchman, has never seen the movie ''Aliens'', which co-starred Paul Reiser.
*** Specifically, a friend of his (Mark) is discussing {{chest burster}}s, and asks Paul if he's ever seen the movies. Paul quickly replies, "Just the first one."
* On a more metatextual ''character'' level than a literal ''actor'' level, ''{{Smallville}}'' falls particularly afoul of this. In every other incarnation of the Superman mythos (comics, TV, movies, radio etc.) Superman is, by the very nature of his existence, a world-famous figure, probably the most famous person on Earth. Therefore all the kinds of nicknames, catchprases and allusions to the fictional character in the real world (e.g. "Faster than a speeding bullet", "The Man of Steel" etc.) are equally well known in the various fictional realities where Superman is actually real (with the exception of "And who, disguised as Clark Kent, mild-mannered reporter..."). But in ''Smallville'', a {{prequel}} show set explicitly in the present day, the viewer is faced with the bizarre dissonance that these characters exist in an early 21st century version of America who's popular culture has '''''not''''' been irrevocably impacted by the existence of Superman (real ''or'' fictional), who originated the entire superhero genre and flooded the lexicon with all manner of specific phrases and ideas.
** This is rendered even more head-numbingly dissonant by the show's sheer volume of [[FourthWall sly references]], homages and [[ShoutOut shout-outs]] to the Superman mythos ''that has yet to actually take place'', with constant winking deployment of terms that contextually shouldn't have been coined yet, like "Man of Steel", "Faster than a speeding bullet", "mild-mannered" etc. etc. They have even shown that words/concepts like "superhero" are already in common parlance, despite their actual existence not yet being known to the wider public.
**** You could argue that most examples are fairly organic; someone sees bullets bounce off Clark and calls him "a man of steel" (not "THE"), etc. We're seeing the in-universe origins of these phrases not the common use of them.
*** Partly justified, since superhero ''comics'' do exist in the ''{{Smallville}}'' universe, since Lex was shown to have been a fan of one such comic (featuring a bald protagonist) growing up, called ''Warrior Angel'' -- ironically a very historically-accurate [[DorkAge '90s style]] archetype. This leads one to wonder who was the first superhero character to be published in the ''Smallville'' universe, since it obviously wasn't Superman...
** There is also some limited amounts of [[MythologyGag doubly-metatextual]] actor paradoxes in later seasons, as past actors associated with earlier film and TV versions of ''Superman'' guest-star as different characters, such as Christopher Reeve, Margot Kidder, Dean Cain, Lynda Carter, Helen Slater... You can't help but wonder why Clark isn't constantly saying "Hey, didn't I used to look like you?" (or, perhaps, "Man, will I really look like ''you'' when I grow up?).
*** It gets [[SelectiveSquick even weirder]] when you consider that Clark's mother is played by Anette O'Toole who previously played his love-interest Lana (no, not [[TheWesley the boring one]]) Lang in ''Superman III'', and that the [[TheVoice AI "ghost" of Jor-El]] featured through most of the middle seasons is brought to life by the very distinctive voice of Terrence Stamp, the indelibly memorable villain General Zod from ''Superman II''.
*** Lampshaded a bit -- the first time Christopher Reeve shows up, they start playing John Williams' Superman themes.
* Hiro Nakamura from ''Series/{{Heroes}}'' is a ''StarTrek'' fan. George Takei, who played Mr. Sulu on said series, plays Hiro's father.
** Kaito Nakamura could well also be a fan- his car's number plate reads ''NCC-1701''.
* Also in ''Series/{{Heroes}}'' some of the characters learn what is going to happen by reading the comic book "9th Wonders." Which is basically the show, but in comic book form.
** However, the comic book tells the story of the show because it was created by a person with precognitive powers.
** [[WallBanger You've really got to wonder]] how a public figure like Nathan would deal with the inevitable questions that would arise when events in the comic precisely mirror events in his life.
* Played with in ''Studio60OnTheSunsetStrip'': Allison Janney of ''TheWestWing'' appears as herself, guest hosting the titular ShowWithinAShow. Timothy Busfield plays the director of said show. Busfield formerly played Janney's character's love interest/husband on ''The West Wing'', and their interactions in the ''Studio 60'' episode play this up. Note that ''The West Wing'' exists in the ''Studio 60'' universe, and fictional Janney was in it, while fictional Busfield apparently wasn't, since he doesn't exist. Confused yet?
** This becomes even ''more'' confusing when you think about how many other actors were in both shows.
** Be glad that the guy who played Josh wasn't in that episode.
** Adding another layer of confusion, the fictional Janney is annoyed at being confused with Christine Lahti. The reporter played by Christine Lahti wasn't in that episode, but she hadn't been gone long.
** It gets worse: the law firm that Sam worked for on ''TheWestWing'' also exists on ''Studio 60''.
* In the penultimate episode of ''TheNanny'', Fran Fine meets actress Fran Drescher. She mentions how everyone says she looks like her, and Drescher is not happy. She also comments on her voice, her hair, and on how the episode she's taping is very similar to what's happening in Fine's life at the moment.
* In the 2004 made for TV movie ''{{Frankenstein}}'', the story of Frankenstein is mentioned a few times. When asked about it, the original creature says that MaryShelley's novel was actually BasedOnATrueStory.
* An episode of ''{{Scrubs}}'' has J.D. mentioning that he thought he noticed the Janitor in the movie version of TheFugitive. Neil Flynn, who plays the Janitor, was indeed in that film. The Janitor later implies that it was indeed him in the movie. Whether this means that all of Neil Flynn's roles in the Scrubsverse are played by The Janitor or if this was a one off is unclear.
** Of course, nothing the Janitor says can be taken seriously. It is perfectly plausible that in the Scrubsverse, the Janitor just happens to look like Neil Flynn and was messing with JD/the Audience's head(s).
** Or the Janitor ''is Neil Flynn'', fallen on hard times.
* In one episode of ''TheHoneymooners'', Ralph Kramden and Ed Norton meet Jackie Gleason and Art Carney. This was done by alternating the actors and their roles: Ed meets Gleason just as Ralph is conveniently absent, while Ralph meets Carney while Ed is out.
* In ''{{Friends}},'' Ross, Joey and Chandler are die-hard fans of ''DieHard.'' However, when they meet Paul Stevens (played by Bruce Willis), he doesn't seem to remind them of anyone.
** In earlier episodes, Ross has Winona Ryder on his "list," but when Rachel's sorority sister shows up, nobody says, "Wow, you look just like Winona Ryder."
** Ross also rejected Susan Sarandon for the list. She also turned up in a later episode, not playing herself.
* In ''{{That 70s Show}}'', characters are shown to be watching ''{{The Brady Bunch}}''. Later, Christopher Knight and Barry Williams appear not as themselves, but as a gay couple. No, really.
* The Disney Channel appears to enjoy this trope. In an episode of ''TheSuiteLifeOfZackAndCody'', Maddie (played by Ashley Tisdale) auditions for the part of Sharpay in ''HighSchoolMusical'' (who was also played by Ashley Tisdale). She claims all her friends say she looks the part, but no one else sees it.
* Similarly in ''HannahMontana'', Robbie Ray (played by Billy Ray Cyrus) puts on a mullet wig and claims to be Billy Ray Cyrus. The woman he's talking to thinks he's crazy and quickly leaves.
* In the ''KateModern'' episode "Fictionality", Ralf Little's character, Gavin, complains that people keep accusing him of being a professional actor.
* In the fictional world of ''TheColbertReport,'' Stephen Colbert's other works do exist, but Colbert (the actor) doesn't -- all of his roles were played by Kevin Spacey instead.
* In the U.S. version of ''TheOffice,'' Creed Bratton plays a fantastical (and waaay crazy) version of himself. He was a bassist in the Grass Roots in the 60s and 70s, and now (instead of acting) works at a paper company.
** In the second Christmas episode, he sings a Grass Roots song on a karaoke machine, which the real Creed Bratton did the vocals for. Wrap your head around that.
** Also on the U.S. ''The Office,'' Michael Scott has mentioned that he is a fan of ''TheWire,'' yet does not notice Holly Flax's strong resemblance to Beadie Russell (both played by Amy Ryan). Nor Charles Miner's resemblance to Stringer Bell (both played by Idris Elba).
** Not to mention the numerous references to Michael's beloved ''{{Whose Line Is It Anyway}}'' and ''{{Saturday Night Live}}'', when the stars of both have appeared as characters on the show, such as Charles "Chip" Esten, Tim Meadows, David Koechner and Nancy Walls, who in addition to being on SNL, is also married to Steve Carell, who plays Michael, in real life.
* VeronicaMars is said to get nightmares when she watches Paris Hilton movies. Quite understandable, as there was a girl at her school played by Paris Hilton.
* The title character in ''SuddenlySusan'' finds herself unable to remember Andre Agassi's first wife -- because it was Brooke Shields herself.
** Similarly, the main character in ''TheNakedTruth'' could only remember that David Duchovny's wife was "that goofy blonde sitcom bimbo"... whom we know as Téa Leoni.
* Likewise, an episode of ''QuantumLeap'' features an heiress played by Brooke Shields, whose resemblance to herself causes no comment from Sam or Al. Then again, in this case it may be a JustifiedTrope because Sam is amnesiac and the show takes place in a timeline which is (at least at first) significantly different from ours.
* One episode of ''SueThomasFBEye'' had Sue (the character) meeting Sue (the real FBI agent that sparked the series); IIRC, one of them said she'd always wanted to be an FBI agent while the other said she'd always wanted to be an actress.
* According to WordOfGod, ''SaturdayNightLive'' does not exist in the world of ''[[{{ptitleolsdue4jfzga}} 30 Rock]]'' for this reason. TinaFey has said that making reference to Eddie Murphy is about the closest the show could ever come to acknowledging the existence of ''SNL''.
** In one episode, Liz and Tracy argue about Wayne Brady. A few episodes later, Wayne Brady appeared on the show as a character.
** In an early episode, Jack mentions watching ''{{Friends}}'' and asks about Ross and Rachel. Both David Schwimmer ("Ross") and Jennifer Aniston ("Rachel") later guest starred. And in an episode after Aniston's appearance, Jenna mentioned her (the actress, not the character).
** [[http://www.myspace.com/lizlemonfans This]] [=MySpace=] page someone created for Liz Lemon lists Tina Fey as one of Liz's heroes.
* Bobby Flay cameoed in an episode of LawAndOrderSVU as a TV chef who's enough like real Bobby Flay that if he wasn't playing himself he might as well have been. He had cheated on his wife--only since Flay is married to Stephanie March (Alex Cabot on SVU) in RealLife, on the show he had no wife to cheat on.
* Both ''SpinCity'' and ''JustShootMe'' have celebrities appear in regular roles as well as themselves, though no celebrity has ever done both.
* In an early ''DawsonsCreek'' episode, Joshua Jackson comments on how great "those ducks movies" were -- a coy shout out to his role as Charlie in the ''Mighty Ducks'' films.
* Averted in ''TheYoungOnes,'' where the characters are quite aware they are in a sitcom which is being broadcast. In fact, in one episode Neil's parents upbraid him for appearing in such a offensive sitcom and asked why he couldn't be in something nice like ''The Good Life.''
* ''ThirdRockFromTheSun'' referenced WilliamShatner a couple of times before he became the Big Giant Head.
** In one episode, the cast asks the Big Giant Head how his flight was & he replies that it was terrible. He says [[TheTwilightZone there was a monster on the wing]] and no one would belive him. Dick assures The Big Giant Head that the same thing had happend to him. Of course, John Lithgow and WilliamShatner played the same part, in the Movie and the series respectively.
** A companion book to the series includes an introduction by John Lithgow despite the book being written in an in-universe manner. Attached to the introduction is a note purportedly written by Dick in which he says he has no idea why it's there, but that Lithgow is an Earth actor from "[[{{Film/Cliffhanger}} some helicopter movie]]".
** Then there was the episode with [[AdamWesting George Takei...]]
* In the real world, the first (test) Space Shuttle was named "Enterprise" in honor of ''StarTrek''. That Enterprise does appear among the models of earlier ships to bear the name that [[StarTrekTheNextGeneration Picard]] keeps in his ready room, and appears in the montage during the opening credits to ''StarTrekEnterprise'', though the reason for its name is presumably different (presumably, the same reason as Kirk's ''Enterprise'': "Enterprise" is a name with a long naval history).
** In ''Star Trek: Enterprise'', the second Warp-5 ship was named the Columbia by the shows writers in tribute to crew of the Space Shuttle Columbia who had recently died in the Columbia Disaster. The in universe reason given for this name, was that it was taken from the second space shuttle, with the implication that the Starship Enterprise is supposed to be named for the space shuttle.
* In a ''SaturdayNightLive'' sketch from the 2008 U.S. election with TinaFey playing Sarah Palin, Hillary Clinton mocks her "Tina Fey glasses".
* On ''WillAndGrace'', BritneySpears is referenced many times by the characters, particularly Jack, who has memorized her dance moves and even swears on her name ("Britney Spears Federline!"). Yet when she appears as a [[StuntCasting special guest star]] as Jack's new co-host, he doesn't comment on how much she looks like his idol.
** Similarly, Jack says, "Me digs Taye Diggs," in one episode. When Grace later [[CitizenshipMarriage married]] Will's boyfriend James, Jack never noted the resemblance.
** On the other hand, when he meets Cher, he initially assumes she's a drag queen dressed as Cher.
** Also there's the paradox presented by Bernadette Peters. One episode opens with Jack holding up a lock of her hair that he recently acquired for a "Broadway Diva Wig" ([[HilarityEnsues leading to a confrontation with Patti LuPone]]), but then in a later episode she plays Karen's sister Gin.
* ''{{Monk}}'': In the season one finale, Tim Daly makes an appearance as himself. Sharona mentions that he was in the show ''{{Wings}}''. So who plays Antonio in the Monk-world? If it's {{Tony Shalhoub}}, Adrian must be pretty sick of people telling him how much he looks like Antonio.
** Sharona is shocked that Monk had never heard of the show, so it's somewhat lampshaded.
* An odd variation on this occured in an episode of ''GreenAcres''. The cast decided to put on a play based on the [[EnforcedPlug "popular television show"]], ''TheBeverlyHillbillies''. That would be fine, except ''The Beverly Hillbillies'' takes place in the same universe as ''Green Acres'', along with ''PetticoatJunction'', with characters frequently [[CrossOver crossing over]] from one show to another. Which means that in ''The Beverly Hillbillies'' universe, there is a TV show called ''The Beverly Hillbillies'', featuring the characters of Jed, Jethro, Granny and Elly May, which those same characters could then watch. One wonders who played the characters on the show.
** Also, one of Lisa's talents is doing Zsa Zsa Gabor impressions. No word on whether she does Eva.
** An episode of ''TheBeverlyHillbillies'' featured Jed Clampett (played by Buddy Ebsen) reminiscing about how he'd seen Buddy Ebsen's song and dance act.
* Invoked by ''{{Lost}}'', possibly intentionally: Sawyer calls Karl "Cheech," and then Cheech Marin shows up playing Hurley's father a scant two episodes later.
* ''FlightOfTheConchords'' is set in a world where ''TheLordOfTheRings'' movies were made and filmed in New Zealand, but nobody mentions the fact that Brett [=McKenzie=] looks alarmingly like [[http://www.youtube.com/watch?v=NF57D0_VV_k one of the elves]].
** Although Bret wasn't in the film for very long, and given the nature of the Conchords characters, it's entirely possible that no-one thinks it worthy of comment.
* In ''CSINewYork'', nobody comments on Detective Mac Taylor's remarkable resemblance to Gary Sinise, but he ''does'' share last names with Sinise's most famous recent role, [[ForrestGump Dan Taylor]].
* Apparently, the American version of ''LifeOnMars'' is [[spoiler:an astronaut going to Mars, thinking of the song "Life on Mars," picturing himself in an American version of ''LifeOnMars'']]. OrWasItADream? (Yeah.)
* In the ''{{Kings}}'' episode "Judgment Day", Prince Jack says, "Everyone wants an old-school lord and master. Cutting a few babies in half." in a reference to the JudgmentOfSolomon... except that since ''{{Kings}}'' is a retelling of the story of Solomon's father, King David, the original JudgmentOfSolomon story shouldn't exist in their universe.
** Alternatively, that universe has the same Bible we do. This would explain why a newspaper thinks the headline DAVID SLAYS GOLIATH means anything. But the parallel between the Bible story and the modern David's career would start to freak people out eventually.
* ''SanfordAndSon'' has Fred G. Sanford winning a Redd Foxx lookalike contest.
* Played with on ''LasVegas'' when "Big Ed" Deline, played by James Caan, is shooting a commercial for the Montecito, and can't act. The director tries to get him to act more naturally by referencing a conversation with Sonny Corleone in TheGodfather. Ed looks confused for a second before saying he has no idea what the director is talking about.
* On the sitcom ''HopeAndGloria'' Alan Thicke played both himself and a talk show host named Dennis Dupree who despises Thicke for looking just like him. This eventually leads to a fistfight between the two during a ''GrowingPains'' reunion on Dupree's show.
* In the ''BuffyTheVampireSlayer'' "Season 8" comics, we see Bufffy and Dawn are big fans of ''VeronicaMars'', although no mention is made to the fact that actors from ''Buffy'' have appeared on ''VeronicaMars,'' as well as show creator JossWhedon.
* An episode of ''8 Simple Rules for Dating My Teenage Daughter'' confirmed that ''ThreesCompany'' definitely exists in-universe, but Paul Hennessy's remarkable resemblance to Jack Tripper is never commented on. To make things even more bizarre, Paul then has a dream sequence resembling ''ThreesCompany'' wherein he plays the part of not Jack, but Mr. Roper.
* ''{{Skins}}'' had Anwar reciting a list of Hugh Grant films in order to stave off orgasm during sex: "I never get as far as ''About A Boy''". ''About A Boy'' being a film in which ''Skins'' actor Nicholas Hoult played a leading role.
* In ''KidsIncorporated'', they did a cover version of "More Than You Know" by Martika, herself a former star of the series, making one wonder if she exists in the ''KI'' universe.
** Almost every character in the series was TheDanza, playing a character of the same name as the actor, so one ''might'' suppose that the character and the actor were meant to be the same person. Ironically, Martika was one of the few characters who ''wasn't'' (her character was named Gloria).
** Bonus point in that said cover was performed by Stacy Ferguson, who by the 1989 season was the last cast member left who had worked with her.
* In one episode of ''HermansHead,'' Louise angrily snaps "I do not!" into the phone, slams the receiver back into the cradle, and then asks, "Herman, I don't sound like Lisa Simpson, do I?" Louise, of course, was played by Yeardley Smith, the voice of Lisa Simpson.
** And conversely, a ''Simpsons'' episode has Lisa chuckling. When Marge asks her why she is laughing, Lisa replies "Oh, just remembering a joke I saw on ''Herman's Head''."
* A complete aversion occurs in the unaired pilot ''Heat Vision and Jack'' -- character actor Ron Silver plays character actor''/assassin'' Ron Silver.
* An inversion exists in the show ''Supernatural''. In the continuity of the show, a series of ''novels'' exists starring the Winchester brothers (the author is a confused [[strike:psychic]] [[spoiler:prophet]]). And yes, there is internet slashfic.
** Sam and Dean are taking a movie studio tour at the beginning of season 2's "Hollywood Babylon." When the tour guide mentions that the next stop is the set for ''GilmoreGirls'', Sam looks uncomfortable and hops off the tram. No one on the tour seems to notice that the guy who just jumped off looks ''exactly'' like Rory Gilmore's first- and second-season boyfriend, Dean Forester (who was also played by Jared Padalecki).
*** In the season 5 episode "Fallen Idols" a shape-shifting god takes the form of Paris Hilton. As Dean rants at the shifter about how shallow idolising Hilton is -- to which Hilton's character seems to agree -- he says he has never seen the recent remake of the horror film ''House of Wax''. At this news Sam looks startled, and a bit disappointed, as both Jared Padalecki (who plays Sam) and Paris Hilton were in ''House of Wax''.
* In the universe of ''{{Fringe}}, StarTrek'' is referenced occasionally. In fact, one delusional character believes that he is a reincarnation of Spock. However, nobody in-universe seems to comment on the fact that ultra-rich industrialist William Bell is played by Leonard Nimoy.
* ''RedDwarf'' plays with it. [[spoiler:The plot of ''Back to Earth'' has Rimmer, Kryten and Cat encounter CraigCharles (Lister) on the set of ''CoronationStreet''. Of course, Craig assumes it's a joke and that they're simply his fellow actors -- until ''Lister'' arrives.]] And it's explained at the end -- [[spoiler:they were in a false reality where ''RedDwarf'' is fiction]].
* In ''There Is No CarryOn In EastEnders'', Chris Moyles discusses the many, many things that can't exist in the ''EastEnders'' universe because of this trope, which may go some way to explaining why the series is such a CrapsackWorld.
* The {{pilot}} for ''FlashForward'' shows an billboard for Oceanic Airlines -- but later on shows a bus ad for ''{{Lost}}''[='=]s final season, implying that ''Lost'' is a show in the ''FlashForward'' universe. [[FridgeLogic Who plays Penny and Charlie in ''FlashForward''[='=]s version of ''Lost''?]]
** The show also had a reference to Hillary Clinton and Sarah Palin, yet it has a fictional president in the same episode. So the 2008 election was exactly the same but with some random white guy winning instead of Obama?
* Played with in ''SonnyWithAChance'' where Sonny (Demi Lovato) meets Selena Gomez, as Selena Gomez, who apparently no longer has a BFF named Demi Lovato, or if she does probably would have mentioned "Hey, my BFF looks so exactly like you it's uncanny." At the end, they tease the idea that Sonny would become Selena's new BFF. It was a very strange episode.
* ''{{Leverage}}'' is full to brimming with ''StarTrek'', up to and including guest stars: [[StarTrekVoyager Jeri Ryan]], [[StarTrekTheNextGeneration Brent Spiner, Wil Wheaton]], and [[StarTrekDeepSpaceNine Armin Shimerman]] have all shown up. Wheaton's character even has the in-universe nickname of TheKobayashiMaru! But hardcore fanboy and Trekkie [[TheSmartGuy Hardison]] [[{{Irony}} notices nothing]].
* In one episode of {{Bones}} the-intern-of-the-week Fisher mentions that he's a [[BuffyTheVampireSlayer Buffy]] fan. Odd, then, that he never noticed that he's working with {{Angel}}...
* The ending of the {{Grand Finale}} of {{Battlestar Galactica}} has [[OurAngelsAreDifferent Head-Six and Head-Baltar]] reading a National Geographic Magazine over a man's shoulder. The man in question is [[WordOfGod Ronald D. Moore]].
[[/folder]]
* In ''{{Glee}}'', Kristen Chenoweth guests stars as April Rhodes, leaving at the end of the episode and making a comment about trying to get into Broadway. A few episodes later, Rachel and Kurt audition for the solo part of [[{{Wicked}} Defying Gravity]]. If there is not a Kristen Chenoweth, who played Glinda?

[[folder: Music ]]

* Katy Perry's "Waking Up In Vegas" has a rather bizarre version. In the video, Perry plays a woman tooling around Vegas with her boyfriend. They hit a run of good luck, then a run of bad luck. You could reasonably assume that some random woman wouldn't be able to phone up Perry's agent or whoever and ask for more money, but the character actually ''plays'' some of Perry's songs on her [[ProductPlacement conspicuous phone]], including "Waking Up in Vegas". Complete with album cover. During a poker tournament, the woman's name subtitle reads "Perry". Presumably, the music video for the song hasn't been released yet, or the character hasn't seen it yet, or it's much different from what it is in this world, and the character just happens to be named "Perry" and looks and sounds a lot like Katy Perry.

[[folder: Theatre ]]

* In the play ''Arsenic and Old Lace'', one character is told repeatedly (and to his [[BerserkButton borderline homicidal annoyance]]) that he looks like Boris Karloff, who played the part in the original Broadway production. The play was written in 1939, so this is OlderThanTelevision.
** This is LampshadeHanging in the play, as the part was written specifically for Karloff.
* In a case of works, rather than actors, existing in universe, {{Rent}} is a 20th century adaptation of ''La Boheme''. In the show, Roger plays a strain of music on his guitar and Mark comments that it sounds like "Musetta's Waltz"... which is from ''La Boheme''. One wonders if the characters noticed how closely their lives reflected the opera.
* In Moliére's play ''The Imaginary Invalid'', which satirizes the medicine of the era, the brother of Argan, the hypochondriac main character asks him if he would like to see a Moliére play. Argan angrily berates Moliére for making fun of doctors. So, the trope is OlderThanSteam.

[[/folder]]

[[folder: Professional Wrestling ]]

* In an angle where Shawn Michaels retires from WWE to work in a cafeteria, he uses the pseudonym "Hickenbottom" to avoid attention. Triple H goes on to make fun of the name. Michaels's real name is Michael Shawn Hickenbottom.
* A TNA skit involved Kevin Nash figuring out new nicknames for Jay Lethal. He pitched names like "Vinnie Vegas" and "Oz" which were Nash's nicknames.

[[/folder]]

[[folder: Video Games ]]

* A bonus cutscene in ''MetalGearSolid 4'', from {{the Verse}}'s [[ShowWithinAShow bizarre television]], shows the actress Lee Meriwether (rather creepily) interviewing the screenwriter David Hayter -- Meriwether and [[FanNickname Dayter]] being the voice actors for Big Mama and Solid Snake respectively. In case we didn't get it, Dayter is dressed in a snakeskin jacket and digital eyepatch, and Meriwether talks to him in the somewhat stilted, poetic, dramatic tones of a ''MetalGear'' character giving an important speech, only addressing him by his full name. Did we mention the ''Metal Gear Solid'' has NoFourthWall?
** More subtly, ''MetalGearSolid 3'' mentions many movies which served as an inspiration for the game, and the first ''MetalGearSolid'' ends ([[MultipleEndings if you submit to the torture]]) with Snake openly discussing his ThemeNaming with his new friend, Otacon (they're called [[TwoThousandOne Dave and Hal]]).
* ''SuperRobotWars'' loves to play with its HeyItsThatVoice casting like this, with characters mentioning other characters' similar voices, and even making {{Shout Out}}s.
* The ''DoubleDragon'' arcade game makes a cameo appearance in a scene in TheMovie adaptation, and is then destroyed during the fight that follows. TheNostalgiaCritic made a big fuss about this in his review of the film and points out that the game being destroyed is [[VideoGameMoviesSuck an appropriate analogy]].
* In ''PaperMario: The Thousand Year Door'', Luigi's parallel adventures are published as serial novels under the title "Super Paper Luigi".
** Captain Lou Albano played Mario in both the live-action and animated segments of ''The SuperMarioBrosSuperShow''. In a particularly memorable live-action segment, Luigi mentions that Mario idolizes Captain Lou, who goes missing. Albano appears at the end of the episode, shortly after Mario leaves...
** In the ''[[SuperMarioBros Super Mario Adventures]]'' comic serial that ran in {{Nintendo}} Power, the first thing we see Princess Peach doing is playing a ''SuperMarioBros.'' game.
* In the ''GrandTheftAuto'' universe, California and New York City don't exist, having been replaced by San Andreas and Liberty City respectively, but some of the songs on the radio still reference California and New York City. For example, Grand Theft Auto IV takes place in Liberty City, but the song list still includes "New York Groove" by Hello.
** A radio DJ in ''Vice City Stories'' explicitly mentions New York at one point.
** Lampshaded in the SA ''LetsPlay'', when the narrator and his friend note Snoop Dogg's rapping about "Compton" is obviously a disguised version of "Ganton". And there's a JackThompson {{Expy}} who thinks that rap music encourages people to violence.

[[/folder]]

[[folder: Webcomics ]]

* The webcomic ''DarthsAndDroids'' is about roleplayers playing a tabletop RPG following the basic plot of the ''StarWars'' movies, but the notes on strip 50 have specifically stated that there is no ''StarWars'' in the universe where they are. They then [[http://www.darthsanddroids.net/episodes/0050.html extrapolates]] on how that would impact things such as Mark Hamill's and Harrison Ford's careers, ''{{Spaceballs}}'', the fate of sci-fi in media, and finally what the webcomic ''Darths And Droids'' would be parodying instead of ''Star Wars'': ''HarryPotter''.
** On top of that, that very sentence links to a sample page from that alternate universe ''HarryPotter'' strip, which includes a full site layout, cast page, FAQ, and a (non-explorable) archive complete with 50 strips of punny stip titles. Then, when the main strip #100 was released, this page was silently edited with the same extrapolation on a world where ''HarryPotter'' never existed, complete with a link to a ''TheSoundOfMusic'' comic with the same bells and whistles. The process repeates every 50 strips, going through ''{{X-Men}}'', ''Film/{{Alien}}s'', ''TheWizardOfOz'' and ''[[ThreeHundred 300]]'' now. Given that we're still partway through Episode II, by the time DarthsAndDroids is finished, the innermost world will be very culturally poor indeed.
*** On the other hand, once you get deep enough into the recursion, the outer layers could actually start reappearing, and the entire thing could come full circle. After all, there's no reason why ''Star Wars'' couldn't exist in a world where the characters are playing a home-brew RPG based on ''300''...
**** Problem is, ''we're'' the outermost layer. What story are ''our'' roleplayers acting out?
** Although its [[SpiritualSuccessor spiritual predecessor]] ''DM of the Rings'' never explicitly referenced this trope, FridgeLogic leads one to wonder how ''[[DungeonsAndDragons D&D]]'' became popular in a world without ''{{Lord of the Rings}}.''
*** The impression that this troper had was that the book existed in the universe and the DM was trying to stick to it, but the players had never read it and knew nothing specific about the plot. Most of the changes from the film are introduced as player improvisations or GM-driven rewrites to cover for mistakes.
* [[http://frakkingtoasters.com//index.cgi?date=20060106 This]] ''Frakking Toasters'' strip has the cast of ''BattlestarGalactica'' sitting down to watch ''BattlestarGalactica''.
* [[http://dizzy.pestermom.com/?p=thcomic59 This page]] of the fancomic ''TroperWorks/TouhouNekokayou'' describes a world without ''{{Touhou}}'' like ''DarthsAndDroids'' did. The author often silently adds more examples to the list ...

[[folder: Western Animation ]]

* In one episode of ''This Is America, Charlie Brown'', the ''{{Peanuts}}'' gang visit the Smithsonian Institution. Among other things, Charlie Brown and Lucy discover the lunar and command modules from Apollo 10 (nicknamed "Snoopy" and "Charlie Brown", respectively), and a ''Peanuts'' Sunday strip.
** In the January 1, 1974 ''Peanuts'' strip, Linus and Lucy watch the Tournament of Roses Parade on TV. Linus asks if the Grand Marshal had gone by, and Lucy tells him yes, "but he wasn't anyone you ever heard of." The actual grand marshal of the parade that year was Charles M. Schulz.
* One episode of ''JackieChanAdventures'' has Jackie and company going to Hollywood. Of course, the actor Jackie Chan doesn't exist and this is confirmed by people asking "Who's Jackie Chan?" Furthermore, once Jackie is found by a studio and HilarityEnsues, a hot-shot director claims that there will never be a Jackie Chan in Hollywood.
* In ''{{Futurama}}'', Katey Sagal (the voice of Leela) is one of actresses in the head museum.
** Matt Groening is there, too.
* In ''SpidermanTheAnimatedSeries'', we at the end have episodes with many realities. In one of those, Spider-Man doesn't exist -- but the comics and films do, and Peter Parker is an actor who plays him.
** This raises the question of who the secret identity of the fictional Spider-Man in that universe is, unless Parker is using TheDanza.
* In one ''DarkwingDuck'' episode, Darkwing tries to sell a screenplay about himself, but the studio rejects him. He threatens: "I think Disney will be more forthcoming!"
* In the ''SouthPark'' episode "Passion of the Jew", Stan and Kenny want to get their money back from Mel Gibson just as they did from ''[=BASEketBall=]''.
** For those that don't get it, Matt Stone and Trey Parker made BASEketball and South Park.
* One issue of ''Teen Titans'' had them explaining to Impulse why he couldn't just release their real names to the public. He wonders why not since they're all in the ''Teen Titans'' and ''Justice League'' comics he's holding. Superboy points out that those aren't their real names. Which confuses Impulse as he's been calling Superman Dirk for months.
* The ''TinyToonAdventures'' episode "Buster And Babs Go Hawaiian" had a brief visual gag involving RobinWilliams as PeterPan in ''{{Hook}}''. The very next episode ("Henny Youngman Day") featured Robin's FunnyAnimal [[NoCelebritiesWereHarmed counterpart]], Robin Killems. Not that big a paradox, though, considering [[RuleOfFunny the nature of the show]].
* In ''What's New Scooby Doo'', JC Chavez hatches a plot to frame Mystery Inc by hiring some movie extras to impersonate them (he impersonated Scooby). When Mystery Inc discover this, Daphne is disappointed that she was played by an extra, saying 'What, was Sarah Michelle Gellar busy?'
