''"InAWorld where trailers are made for movies that will never exist..."''

The show's great. You've seen every episode and bought the UsefulNotes/{{DVD}} collection. And there, tucked away in the extras, is the Holy Grail: the trailer for the movie.

But something's not quite right. Perhaps the trailer gives a 1999 release date, and it's already 2007. Perhaps the characters in the trailer are parodies of themselves. Perhaps?

Perhaps it's a spoof. The movie isn't going to be made, and there was never any intention of making it; it was just the production crew having a bit of fun.

Never mind. At least the trailer's funny -- we hope.

This is the LogicalExtreme of TrailersAlwaysLie - while that trope is about trailers misrepresenting various portions of a real film, this is about a trailer lying about an ''entire work.'' That being said... sometimes the trailer is so well-received that [[{{Defictionalization}} people actually make the movie]].

Compare TrailerSpoof, which is for a real movie, just not the one you thought it was.
!!Intentional spoofs:

* [[http://www.youtube.com/watch?v=sk5Q6cDoZCg Falling in Lamb]] was an Australian commercial from a few years back, [[CaptainObvious advertising lamb]]. It was short-lived, though, possibly due to the number of calls to local theatres enquiring about the release date of this new romantic comedy.
* [[http://www.youtube.com/watch?v=YoCLxp2W9xE Lucky Star]] (no, not the [[Anime/LuckyStar anime]]), starring Benicio Del Toro. There has to be more than one person who saw it repeatedly on TV and never realized it was a car commercial.
* There was a trailer for an excellent sounding movie playing in a local movie theatre, but it is disappointing to find out it's just an [[MundaneMadeAwesome anti-dandruff shampoo ad]].
* [[https://www.youtube.com/watch?v=jo639TwDE20&feature=youtu.be&t=57s There's a whole series of fake trailers]] used by the AMC theater chain, to warn audiences to pipe down and turn off their personal electronics. Each one opens as expected for its genre (period Kung Fu flick, Creator/{{Disney}} TalkingAnimal cartoon, etc), only to be derailed when a cell phone rings, distracting the characters at some critical moment. HilarityEnsues.
** Speaking of silencing your cell phone, a policy shown in Israel movie theaters called "Fatal Call" starts out like a movie trailer, but you know from the beginning, since it takes place in a movie theater. The trailer contains a girl who is eating popcorn when her cell phone rings, and a voice from the phone says "Sarah! You shouldn't have answered! You should have left your cell phone off!" Then, Sarah chokes on her popcorn. Ah...don't you just love happy endings?
* [[http://www.youtube.com/watch?v=n3ckFAdY3s4 Scarlet]] looked like ads for a slick, spy-fi SpiritualSuccessor to ''Series/{{Alias}}.'' It ''was'' an ad for a TV series, as in a series of TV's made by LG. Note a lot of the dialogue, such as "Putting her in every home on the planet," and saying "She's gonna change TV."
* Geico made a trailer for a fake reality show titled ''[[https://www.youtube.com/watch?v=Lomy7xAVDKE Tiny House]]'', about a couple living in a house that was built too small.
* [[http://www.youtube.com/watch?v=MkojpLJOBHU Connecting Flights]], a holiday RomCom ChickFlick that checks off every [[ClicheStorm cliche in the book]] in the span of about 20 seconds, only for the stinger be that it's really an ad for Sears's line of appliances.
* Cineplex theatres in Canada has a trailer for a time-travel movie that looks like a bigger budget version of ''Film/{{Primer}}''. The protagonist has to travel back in time to meet his girlfriend at a sold-out movie. Quote: "If you're not there tonight, I won't be here tomorrow." OR you could order tickets online.
* [[http://www.youtube.com/watch?v=UWoZ3o3-0tQ Here]]'s an action/comedy thriller starring the Advertising/MAndMs Spokecandies!... except it turns out to be yet another [[NoTalkingOrPhonesWarning "turn your cell phone off" ad]].
* Ford made [[https://www.youtube.com/watch?v=jiEZE8EkRw0 a pretty epic one]] for their Summer Spectacular.
* Similar to the M&Ms one, Advdertising/{{GEICO}} has one with a NoTalkingOrPhonesWarning in one of the "it's what you do" spots where a secret agent is chased up to a roof where there's a waiting helicopter, only to a phone call that turns out to be his mother, rambling on about some squirrels in the attic and asking if he's at a zumba class because there's so much noise.
-->'''Announcer''': If you're a mom, you call at the worst time. It's what you do.
* Creator/HillaryRodhamClinton[='=]s 2016 presidential campaign created an attack ad against Donald Trump that was done in the form of a [[https://www.youtube.com/watch?v=C0ei2h-0QDU commercial for Trump "University"]].

[[folder:Anime and Manga]]
* One omake for ''Manga/BlueSeed'' was a kaiju movie parody staring the cast. The English version was even done with odd tone variations and poor lip-syncing like early dubbed films, capped off with informing viewers it was all a big lie.
* ''Anime/ElfPrincessRane'' is a two-episode OAV that ends with trailers for the completely nonexistent third and fourth episodes.
* A similar fate had befallen a number of short OAV series, especially during the 80s and 90s: The material produced was intended to be a pilot for a longer work, but the series was canned before it ever got off the ground. While not all of them necessarily had trailers produced advertising the dead-in-the-water series, see also the "in the next episode" bit advertising "Knight of Lemon" at the end of [[Anime/NGKnightLamune40 "Knights of Ramune"]] (which is promptly followed by a note that the series had been cancelled).
* The second episode of ''Manga/ItsudatteMySanta'' has a trailer for the third episode, featuring Mai, [=MaiMai=] and Shirley living with Santa, a cooking competition between Mai and Shirley, and a sleigh and reindeer which turn into a HumongousMecha to battle a presumably possessed Miss Noel. The trailer is revealed to be fake at the end.
* ''[[http://www.youtube.com/watch?v=7lFJC0ywHQk Magical Girl Pretty Sammy The Motion Picture: The God Boys VS. Magical Girls]]'' was included as one of the extras on the final ''Anime/MagicalProjectS'' UsefulNotes/LaserDisc and DVD. It had many fans believing that a movie was forthcoming, and resulted in a petition (unsuccessful) to get the movie made. What in anime ''doesn't'' it parody? "Oshioki desuu, haaaii!"
* ''Anime/MaiOtome'' had [[https://www.youtube.com/watch?v=Vs8rO8UICT0 a fake trailer]] on the [=DVDs=] for the ''Anime/MaiHime'' movie. Many people on [=AnimeSuki=] and Wiki/{{Wikipedia}} don't realize that it's a joke and keep asking when the movie will be released despite the release date being listed as ''20006'' [sic].
* The last page of second volume of the hentai doujinshi ''Take on Me'' is intended to look like an advertisement for a anime adaptation. Far, far too many people have asked where they can find this movie, when it is coming out, etc. It's not, it's just the artist [[MindScrew mind-screwing]] the audience.
* The [[http://www.youtube.com/watch?v=sn8PPgfPNnU seventh DVD special]] (NSFW) of ''VisualNovel/RumblingHearts'' was a trailer of series' {{Remake}} [-{{IN SPACE}} WITH Franchise/{{GUNDAM}}S!-]
* Similarly, the [[http://www.youtube.com/watch?v=yrSfREtBjAs fifth DVD special]] of ''Anime/ShatteredAngels'' was a trailer for ''The True Kyoshiro To Towa No Sora'', a remake of the original series with a grander sci-fi plot and much more RomanticTwoGirlFriendship (with Kuu and Setsuna as the OfficialCouple). TheyWastedAPerfectlyGoodPlot, actually...
* ''Manga/{{Hyakko}}'' does this in episode six of the series, giving the audience a preview that has, among other things, an army of Mecha-Torakos, Evil!Suzume and a midair battle between Torako and her brother. It's also completely fake.
* The first volume of ''The Melancholy of Suzumiya Manga/HaruhiChan'' contains a preview of a manga dealing with Itsuki's becoming an esper and joining the Organization... except Kyon disillusions him next page with a "Yeah, that trailer was a fake, ''Haruhi-chan'' is a gag-manga".
* The final episode of ''Manga/SeitokaiYakuindomo'' includes a preview for a MagicalGirl show called ''Magical Mako'', claiming that it will take over their timeslot the following week. [[OnlySaneMan Takatoshi]] then [[BreakingTheFourthWall pulls out the TV schedule]] and points out that they're really be replaced by the second season of ''Anime/{{Hakuouki}}''.
* Subverted with ''Manga/{{Gintama}}'', with the trailer for the Benizakura arc movie. It first shows up in the third season, when the characters admit that the trailer is fake. During the next season, the trailer is played again and the characters say it is actually coming out. Played straight with the second trailer, where the trailer is played and Gin follows up by telling us it is all a lie.
* The last volume of ''Anime/CarnivalPhantasm'' included an animation for the original concept of ''VisualNovel/FateStayNight'', entitled ''Anime/FatePrototype''. It was basically this trope.
* The special edition of the ''Anime/{{Magical Girl Lyrical Nanoha The Movie 2nd As}}'' Blu-Ray/DVD included two {{Omake}} showing hypothetical shows featuring the Wolkenritter: ''Mahou Kazoku[[note]]Magical Family[[/note]] [[http://www.youtube.com/watch?v=rmgzRbZu4M8 Lyrical Wolken]]'' and ''Iryou Shoujo[[note]]Medical Girl[[/note]] [[http://www.youtube.com/watch?v=yY0fzHSkb2Y Medical Shamal]]'', which are broadcasted in [[FictionalCounterpart BHK and other Belkan and Mid-Childan channels]].
* TheStinger at the end of ''Anime/LupinIIIVsDetectiveConanTheMovie'' is a trailer for ''[[https://www.youtube.com/watch?v=MBwT08ifhUY Lupin III vs Kaitou Kid]]'', with a 2020 release date. [[BreakingTheFourthWall Then Conan appears and tells to the audience that it's not real]].
* A New Year's 2017 promotional stream for the ''Fate'' part of the Franchise/{{Nasuverse}} had [[https://youtu.be/kSdv9S-VTjk?t=2m37s a trailer for an anime adaptation]] of ''Fate/koha-ace'', a gag spinoff, play for about fifteen seconds before abruptly getting shoved aside by [[VisualNovel/FateStayNight Rider]], who explains that it's a fake announcement. [[VideoGame/FateGrandOrder Okita Souji and Oda Nobunaga]], the stars of the fake anime, are understandably displeased by this development.

* This [[http://www.youtube.com/watch?v=_hTiRnqnvDs fanmade trailer]] for ''GreenLantern''.
* It's really more of a case of "Real Movie, Fake Trailer" but there's [[http://www.youtube.com/watch?v=yfiU-Q0YerE this]] trailer for ''Film/MightyMorphinPowerRangersTheMovie''...
* This [[http://www.youtube.com/watch?v=IXnqikS6D5A fan-made trailer]] for a ''Series/{{Glee}}'' [[TheFilmOfTheSeries movie]] called "[[QueerRomance When Kurt Met Blaine]]". The creator said that she [[InvokedTrope made the trailer as realistic as possible]], which ''does not help at all.''
* Small screen example: After ''Series/StarTrekEnterprise'' rolled out its special opening to its two-part "In A Mirror Darkly" episode, a number of Trekkies and other fans came up with MirrorUniverse openings for other ''Franchise/StarTrek'' shows, including ''Series/StarTrekTheNextGeneration'' and ''Series/StarTrekVoyager'', among other spoofs and parodies.
** [[http://www.youtube.com/watch?v=5fFoWjAbn58 A Star Trek: The Next Generation Mirror Universe opening]]
** [[http://www.youtube.com/watch?v=sZblw7n2t6o Another Star Trek: The Next Generation Mirror Universe opening]]
** [[http://www.youtube.com/watch?v=vo-5AeCIYXU A Star Trek: Voyager Mirror Universe opening.]]
** There was also at least one trailer for a ''Series/StarTrekVoyager'' [[http://www.youtube.com/watch?v=VjbIUHBz1LY movie.]]
** Then there's the ''[[http://www.youtube.com/watch?v=f3q5o55BJYw Star Trek: Emergency]]'' opening, which is what ''Series/StarTrekVoyager'' would probably be like from the Doctor's point of view.
* [[http://tvtropes.org/pmwiki/posts.php?discussion=3m4uvlo3cr9ksrpsdzmzhd78&page=60#1489 This]] text-only trailer for ''Fanfic/KyonBigDamnHero''.
* [[http://www.youtube.com/watch?v=f-w98pNAi9A This]] trailer for a [[Series/GameOfThrones Westerosi]] rom-com starring [[KnightInShiningArmor Brienne of Tarth]] and [[TheOathbreaker Jaime Lannister]].
* ''FanFic/MegaManDefenderOfTheHumanRace'' has this in text format for Evelyn Ray's latest horror flick.
* [[http://www.youtube.com/watch?v=KV8sQrJa59I Fan trailer]] for ''[[Literature/TheWheelOfTime Wheel of Time: The Eye of the World]]''. Made of fragments from about 20 sources (from ''Film/TheLordOfTheRings'' to ''VideoGame/TheWheelOfTime'' {{FPS}}, from ''Film/{{Troy}}'' to ''Film/HarryPotterAndTheHalfbloodPrince'') set to Music/{{Nightwish}} music.
* The [=CGISociety=] had a competition where people submitted trailers for a movie for a book of Creator/GregBear's 1985 scifi novel ''[[Literature/TheWaySeries Eon]]'', that left Literature/TheWaySeries fans drooling. [[https://www.youtube.com/watch?v=VrLo1qUkCH8 Watch one here.]]
* [[https://www.youtube.com/watch?v=--J0yitgw8s A fan trailer]] for a potential third Film/{{Tron}} movie made excellent use of the ''Film/TronLegacy'' DVD extras, a couple clips of Film/{{Inception}}, some sizzle reel promo footage for ''Legacy,'' the Music/DaftPunk "Derezzed" video, and cutscene footage from VideoGame/TronEvolution to set up a scenario where Dillinger Junior (a bit character in ''Legacy'') is being used by a resurrected Master Control to wreak havoc.
* ''WesternAnination/{{Thundercats}}'' [[http://www.youtube.com/watch?v=fb50GMmY5nk Live Action Movie.]] Looks really damn good, but alas, it's fake, made by editing footage from various other movies.
** From the same author, {{Superman}} [[http://www.youtube.com/watch?v=0NIFvrV4VP4 Reborn.]] The eponymous character in this trailer has Christopher Reeve's body and Tom Welling's face.

* All of the trailers in ''Film/{{Grindhouse}}'' (''Film/{{Machete}}'', ''Thanksgiving'', ''Don't!'', ''Film/HoboWithAShotgun'', and ''Werewolf Women of the SS''). In an unusual twist, both ''Machete'' and ''Hobo With a Shotgun'' got such a good reception that they [[{{Defictionalization}} were made into actual movies]]. And then Machete [[Film/MacheteKills got a sequel]], [[RecycledInSpace with another in the works]]. Creator/EliRoth is also currently working on a movie for his ''Thanksgiving'' trailer.
* ''Film/HardwareWars'', by Ernie Fosselius, was made seven months after the first release of ''A New Hope'' and is reputedly Creator/GeorgeLucas' favorite ''[[Film/ANewHope Star Wars]]'' parody.
--> "You'll laugh, you'll cry, you'll kiss three bucks goodbye!"
* The trailer for ''WebVideo/ItalianSpiderman'' has to be seen to be (dis)believed. SUSPENSO! It was so well-received that it's was expanded into a series, presented as parts of a recently recovered copy of the full movie.
* The trailer for a "sequel" to ''Film/KungPowEnterTheFist'' was actually just deleted footage spliced together. In a strange twist, the film's producer tried to actually produce the sequel, but was denied funding as the original had been a box office flop.
* The Creator/MelBrooks parody ''Film/HistoryOfTheWorldPartI'' ends with a fake trailer for a part II. Wiki/{{Wikipedia}} explains this as being a reference to the book ''The History of the World'', whose author was beheaded before he could write a part 2.
** See! ''[[http://www.youtube.com/watch?v=ybuKQf9p5jg Hitler on ice!]]''
** See! ''A viking funeral!''
** See! ''[[http://www.youtube.com/watch?v=-_jLnrUXJNM Jews ... in ... Spaaaaaaace!]]''
** The final number of the musical adaptation of ''Film/YoungFrankenstein'' mentions a ''Film/BlazingSaddles'' musical coming 'next year'. That was 2010, so it very well may have been an example of this trope.
* ''Film/TheKentuckyFriedMovie'' includes trailers for parodies of other films, including ''Catholic High School Girls In Trouble'', ''[[https://www.youtube.com/watch?v=sm8txY989Iw That's Armageddon!]]'' and ''[[https://www.youtube.com/watch?v=ORuENEBX5sE Cleopatra Schwartz]]'' (a parody of a {{blaxploitation}} film called ''Cleopatra Jones'').
* This is how Creator/TreyParker's ''Film/CannibalTheMusical'' began. He made a fake trailer for film class and was told to make the movie by his teacher.
* Ben Stein's movie ''Expelled: No Intelligence Allowed'' was criticized for, amongst other things, lying to the interviewees about the nature of the film and [[ManipulativeEditing cutting up interviews to change the meaning of what they said]]. UsefulNotes/RichardDawkins, one of the scientists who claims to have been misquoted, produced his own [[http://www.richarddawkins.net/article,2478,Sexpelled-No-Intercourse-Allowed,RichardDawkinsnet satirical trailer for a possible sequel]].
* ''Kill Buljo'', a spoof trailer of "Kill Bill" set in a Scandinavian indigenous people's setting, actually ''was'' filmed later. Supposedly, Creator/QuentinTarantino quite liked it (the director eventually made [[Film/DeadSnow a movie about a buried treasure guarded by Nazi zombies]]).
* ''Film/TropicThunder'' featured not one but ''four'' of these before the movie even starts, [[https://www.youtube.com/watch?v=JwViH1DnK9Y each featuring one of the main characters]]. The first is a fake commercial featuring Alpa Chino (a fictional rapper) as a spokesman for the [[{{Defictionalization}} now-real]] "Booty Sweat" drink, the second for the sixth installment in fictional action star Tugg Speedman's blockbuster ''Scorcher'' franchise, the third for an Creator/EddieMurphy-style comedy called ''The Fatties: Fart 2'' starring fictional comedian Jeff Portnoy, and the fourth for ''Satan's Alley'', an OscarBait art film about gay medieval monks starring (the fake) Kirk Lazarus and (the real) Tobey Maguire.
* Francesco Vezzoli's short film [[http://www.youtube.com/watch?v=cLK4mA9GgMo Trailer for a Remake of]] Creator/GoreVidal's ''Caligula'' (NSFW for sexual content and nudity) is a fake trailer for a Caligula movie starring, among others, Benicio Del Toro, Creator/HelenMirren and Karen Black.
* The movie ''Movie Movie'', a spoof of old double features, had, in between its two "features," a trailer for a fictitious UsefulNotes/WorldWarII air battle movie called ''[[https://www.youtube.com/watch?v=e8sRVGGlY3c Zero Hour]]''.
-->Fight with them! Laugh with them! Love with them! And even die with them the [[HeroicSacrifice death of heroes]] who will [[FamedInStory live forever]]!
* ''Closet Cases of the Nerd Kind'', a parody of ''Film/CloseEncountersOfTheThirdKind'', which involves aliens who hit people in the face with pies for no reason, singing mailboxes, and Darth Vader on a motorcycle telling the hero to stop holding up traffic.
* [[http://www.youtube.com/watch?v=w3NwB9PLxss Movie: The Movie]] from Creator/JimmyKimmel is a massive GenreBusting fake trailer starring a serious number of A-list Hollywood talent.
* In ''Film/TheHoliday'', one of the leads runs a trailer editing company. [[https://www.youtube.com/watch?v=HM3gLJT5_qQ The one shown in the movie]] is for a movie called ''Deception'' starring Creator/LindsayLohan and Creator/JamesFranco
* ''This Is Not A Movie'' has some parody movie commercials embedded into its free-for-all storyline, such as "[[Franchise/TheTexasChainsawMassacre The Jesus Chain Saw Massacre]]", "Reagan Force: Operation Freedom Lies", and "[[Film/TheEmpireStrikesBack The System Strikes Back]]".
* Produced by Universal Studios themselves and uploaded just in time for ''Film/BackToTheFuturePartII''[='=]s [[{{Zeerust}} 2015]]: it's [[https://www.youtube.com/watch?v=Pl092whRLlI a trailer for]] ''[[Film/{{Jaws}} Jaws 19]]'', with synopses for all of the Jaws movies up to that point:
-->''Jaws'' made you afraid to go into the water. ''Jaws 2'' made you afraid to go back in the water. ''Jaws 3-D'' was a new dimension in terror. In ''Jaws 4: The Revenge'' it was personal. Then it was just business (''[=Jaws$5=]''), then pure pleasure (''Jaws 6''). ''Cyber Jaws'' (''J.A.W.S. 7'') made you afraid to log on, and ''[[Franchise/RoboCop RoboJaws]]'' (''Jaws 8'') made you afraid of robotic sharks. Then Chief Brody's grandson assembled a super team of shark hunters (''Jaws 9''). In ''Jaws 10'' it was Man vs. Shark vs. All the terrors of the deep. Outer space (''Jaws 11''), then a prequel (''Jaws 12''), and a sequel to the prequel (''Jaws 12: Part II'' or ''Jaws Part XIII''), and then a new era in terror began (''Jaws 14''), Jaws started a family: battled a Russian shark named Ivan Sharkovsky (''Jaws 15''), [[BigApplesauce took a bite out of the Big Apple]] (''Jaws 16''), and learned about love from a mysterious stranger (''[[Film/FiftyShadesOfGrey Jaws 17: Fifty Scales of Grey]]''). ''Jaws 18: Origins'', the mind blowing reboot. Now the oceans are disappearing and to save their home, the sharks must attack. ''Jaws 19'': '''This time it's really, ''really'' personal.''' Coming soon.
* The ''Anime/{{Yatterman}}'' live action movie ends with a fake SequelHook, with a "Next episode preview" showcasing Dokurobei's deadbeat twin brother seeking revenge, the screen debut of Yatterpelican against an updated version of the squid mecha from the movie's climax and Doronjo wearing a white version of her usual outfit (Omocchama suggests it's a "wedding dress" version).

* Later editions of the novel ''Literature/ThePrincessBride'' feature a preview chapter of a prospective sequel at the end, a sequel which the author has never quite gotten around to writing.
** Because Creator/StephenKing [[ShowWithinAShow already got the rights to do the adaptation]].
* Creator/StanislawLem wrote a book or two made entirely of introductions to nonexistent books.

* Music/PepeDeluxe put together an "[[https://www.youtube.com/watch?v=qxx-lrVZpQE album trailer]]" for ''Music/QueenOfTheWave'', depicting the story as a 60s SwordAndSandal film. It mainly consists of recut footage from the 1961 Italian film ''Film/TheGiantOfMetropolis'', with new voiceovers.

** On a similar note is [[http://www.youtube.com/watch?v=P50d9xsLzB0#! this]] trailer for a graphically updated version of ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]''.

* ''[[http://www.youtube.com/watch?v=YMJJxKBk5s4 The King of Famicom]]'', from the creators of ''WebVideo/MichaelQuest'', is a mock-up of a MassivelyMultiplayerCrossover FightingGame featuring the 8-bit characters of Creator/{{Nintendo}}, Creator/{{Capcom}}, Creator/{{Irem}}, Creator/{{Sunsoft}}, Creator/HudsonSoft, [[Creator/BandaiNamcoEntertainment Namco]] and Creator/{{Konami}}. Amusing finishers include [[VideoGame/{{Ufouria}} Hebereke]] Popoon-ing VideoGame/{{Kirby}}, VideoGame/{{Spelunker}} cursing [[Franchise/SuperMarioBros Mario]] with FallingDamage, and Konami Man giving [[VideoGame/BubbleBobble Bubblen]] a DiagonalCut with Creator/{{Konami}}'s IconicLogo.
* ''VideoGame/NoMoreHeroes2DesperateStruggle'' featured the sub-game "Pure White Lover Bizarre Jelly 5," a BulletHell game starring {{Moe}} [[MagicalGirl Magical Girls]], which also featured [[https://www.youtube.com/watch?v=gqaz1kDz14w a trailer for an anime of the same name]].
* A YouTube user managed to put together a lot of cutscenes from ''VideoGame/MassEffect3'', in the style of a movie trailer. [[https://www.youtube.com/watch?v=AGD6Tb8oZZI Here's the result.]]
* [[Creator/JamesRolfe Cinemassacre]] created a trailer for a movie adaptation of the notoriously bad [[http://cinemassacre.com/2015/11/24/dr-jekyll-mr-hyde-movie-trailer/ Dr. Jekyll & Mr. Hyde NES game]] that was famously reviewed by [[WebVideo/TheAngryVideoGameNerd the Nerd]].

* ''WebAnimation/HomestarRunner'' has done this a few times, most famously making a fake trailer for a movie based on their game ''VideoGame/PeasantsQuest''. According to their website, there already is a full-length ''Peasant's Quest'' movie: "its 'full length' is three minutes" (the length of the trailer).
** See also the [=SBEmail=] "Narration", where Strong Bad narrates the lives of the residents of Free Country, USA as though they were movie trailers: Homestar and Marzipan are a couple torn apart by a novelty chef's hat, an argument between Coach Z and Bubs over napkins apparently [[SeriousBusiness leads to the fall of an empire]], and Strong Sad gets a dead goose thrown at him.

* ''WebAnimation/{{Arfenhouse}} The Movie 3: [[http://www.newgrounds.com/portal/view/161186 Kill Billy]]''. The actual third ''Arfenhouse'' movie was a perfunctory TakeThat to fans who demanded it really be made.
* ''Machinima/RedVsBlue'' showed [[http://www.youtube.com/watch?v=1amVKTN5IuM this]] for Youtube's Geek Week.

[[folder:Web Originals]]
* One memorable trailer was for the potentially ''awesome'' film, ''[[http://www.cracked.com/video_16451_coming-soon-batman-vs-batman-vs-batman.html "Batman vs Batman vs Batman"]]''. Think about it.
** [[http://www.youtube.com/watch?v=WnZRU8RahTY The]] [[http://www.youtube.com/watch?v=6RppxhOdby4 Batman]] [[http://www.youtube.com/watch?v=8pIV4AgHcoc Complex]]. Trailers have been made for this fake movie, which crosses Film/TheDarkKnightSaga and ''Film/{{Inception}}'' and has a premise that's as mind wrapping as the latter.
* There's also the hilarious parody of trailers in general known as [[http://www.youtube.com/watch?v=w8JPEq0Qp4Q The Mother of All Trailers]], starring Creator/EdwardNorton.
* [[https://youtu.be/vchOGKIlUnA Here's]] one for ComicBook/KingdomCome.
* User [[http://www.youtube.com/user/bloodrunsclear Bloodrunsclear]] has made over 500 fake trailers over the years, based on the most disparate sources. While the results do not always hit the mark, a big increase in quality, editing and consistency in his more recent works is evident, compared to his earlier attempts. Some examples: ''VideoGame/SystemShock 2'' [[http://www.youtube.com/watch?v=1bbNVbGAtpI]], ''Manga/ElfenLied'' [[http://www.youtube.com/watch?v=c8xedjFaPzQ]], ''Manga/{{Akira}}'' [[http://www.youtube.com/watch?v=cMI-3eN_p9A]], ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' [[http://www.youtube.com/watch?v=hIIWwyG4_xI]], ''VideoGame/CarnEvil'' [[http://www.youtube.com/watch?v=qw3QRIk7CQU]], ''Webcomic/{{Homestuck}}'' [[http://www.youtube.com/watch?v=EapEknJ5XiY]] ,''VideoGame/ModernWarfare3'' [[http://www.youtube.com/watch?v=dSDlRhg9yww]].
* Mikenel's ''[[http://www.youtube.com/watch?v=Ozc_zHWo9jk Insert Title Here]]''. An 2010 April Fool's Day gag based on his own [[http://mikeinel.deviantart.com/art/Haruhi-and-Zim-61197129 fanart]], it promised a crossover between characters from ''WesternAnimation/InvaderZim'' and ''LightNovel/HaruhiSuzumiya''. While there are things to nitpick such as continuity errors, it is otherwise convincing.
* There's a brutal parody of a DarkerAndEdgier Franchise/ArchieComics [[http://www.youtube.com/watch?v=djRAiiFlCy8 here]].
** And yet LifeImitatesArt with Series/{{Riverdale}}.
* [[http://www.youtube.com/watch?v=gG1ex0AAU5c This trailer]] for a ''VideoGame/MarioKart'' movie.
* This two-part trailer([[http://www.youtube.com/watch?v=Lu5tJGfZsgc here]] and [[http://www.youtube.com/watch?v=iU0Ivs55-Hw here]]), Creator/OrsonWelles' "The Bat-Man"), was inspired by a widely-circulated (and debunked) internet rumor that Orson Welles wanted to direct a Batman movie during the 40s. The trailer consists of clips from a 40s Batman serial, along with other movies(including ''Film/CitizenKane'' and ''Film/TheThirdMan''), casting Orson Welles as Bruce Wayne, Joseph Cotton as Jim Gordon, Edgar G. Robinson as the Penguin, Marlena Dietrich as Catwoman and Conrad Veidt(with clips of "Film/TheManWhoLaughs"--ironically, the original inspiration for the character) as the Joker.
** An uber-cool [[http://www.youtube.com/watch?v=ZNBp1BFwrIE fake trailer]] for ''Ocean's 14'', co-starring Robert de Niro and Daniel Craig (yes, as Film/JamesBond)...
* Used, but then turned into a subversion, by ''WebVideo/YuGiOhTheAbridgedSeries'': There was a trailer made for an Abridged version of ''Anime/YuGiOh: TheMovie'', that was never intended to be made into a full movie. Eventually, however, after a lot of people asked for it, Little Kuriboh did make a half-hour version of the movie, but with ''none'' of the lines from the original trailer (except one reference).
* ''VideoGame/{{Minesweeper}} TheMovie'' [[https://www.youtube.com/watch?v=LHY8NKj3RKs trailer]].
* [[http://youtube.com/watch?v=QQyfQ7RMOXsn_id=annotation_594699 Grayson]], a trailer for a film where a retired Robin once again takes up the mantle to solve the mystery of Franchise/{{Batman}}'s death. A script was even produced for a full feature and is available to read online.
** In that spirit is also [[http://www.dailymotion.com/video/x2izoh_batman-arkham-asylum-fan-trailer-en_shortfilms Batman: Arkham Asylum]], a Spanish-language adaptation of Creator/GrantMorrison's influential and mindtwisting ''Comicbook/ArkhamAsylumASeriousHouseOnSeriousEarth''.
* ''[[http://www.youtube.com/watch?v=fWL6j0SvqV0 Pac Man: The Movie.]]'' It actually looks half-decent apart from the Special FX.
* Ride/UniversalStudios Orlando brings us the climax of their ''Disaster!'' show, entitled ''[[http://www.youtube.com/watch?v=6yVxZxGn888 Mutha Nature]]'' (rated "Blockbuster" by the Academy of Film Review).
* By the way, the scene is so fertile it was prompted an international festival/contest of sorts, [[http://www.teaserland.com Teaserland]].
* Some people decided to tease ''VideoGame/{{Touhou}}'' fans with [[http://www.youtube.com/watch?v=W9mVq2kZ9co a sophisticated trailer]] for an EasternRPG entry into the series.
* [[http://www.youtube.com/watch?v=vD4OnHCRd_4 This]] well done trailer for a ''Film/{{Titanic 1997}}'' sequel.
** It has a [[http://www.youtube.com/watch?v=ZX-QVpmG7b4 sequel]].
* And here's [[http://www.youtube.com/watch?v=VE_1KlWFJyA Tetris - The Movie.]]
* [[http://www.youtube.com/watch?v=YDDHHrt6l4w This]] fake opening (perhaps technically not a trailer) for a Saturday-morning ''ComicBook/{{Watchmen}}'' cartoon features hilarious LighterAndSofter AdaptationDecay and a ClicheStorm of 1980s cartoon tropes.

* [[http://www.youtube.com/watch?v=MMXME2pm83c The Sims.]]
* [[http://www.youtube.com/watch?v=arP1YKAyR_g Where's Waldo?: The Movie.]]
* Many trailers made for a ''Justice League'' movie are sadly just spliced scenes from ''Film/TheDarkKnightSaga'' and ''Film/SupermanReturns'' or ''Series/{{Smallville}}'' with a handful of brief cuts of what are supposed to be the other heroes. A few even add in close up shots of Creator/MeganFox from the Transformers movies that make little sense even if you know of the untrue rumors about Fox starring in a WonderWoman movie.
* ''WebVideo/TheHorriblySlowMurdererWithTheExtremelyInefficientWeapon''. Even the trailer is long (10 minutes!)
** A rare case of this trope being TropesAreNotBad, since the supposed full-length movie would be '''''over 9 hours long.'''''
** And now this trope doesn't apply as much - ''there's a movie in the making.'' Maybe.
* [[http://www.dailymotion.com/video/xb4cs0_youre-not-cruise-trailer-im-not-the_shortfilms You're Not Cruise]].
* From the people who brought you ''Literature/HarryPotterAndTheHalfBloodPrince'' and ''MenaceToSociety'', [[http://www.youtube.com/watch?v=CS7xDS24GGE Dangerous Wands]].
* ''WebVideo/ATrailerForEveryAcademyAwardWinningMovieEver can be seen'' [[http://www.cracked.com/video_18156_a-trailer-every-academy-award-winning-movie-ever.html here]]
** And its send-up, ''[[http://www.youtube.com/watch?v=oeIRQol52HU The Trailer For Every Christian Movie Ever]]''.
* ''Fanfic/MyImmortal [[http://www.youtube.com/watch?v=ue7s2j1_p6s The Movie]]''.
** Which goes well with ''other'' bad fanfic trailer Fanfic/LegolasByLaura. [[http://www.youtube.com/watch?v=IECKGp-tLb0 Right here.]]
* ''Film/AWalkToRemember'' and ''Film/FiveHundredDaysOfSummer'', [[http://www.youtube.com/watch?v=Sce2LRxFqNk anime]] [[http://www.youtube.com/watch?v=4AJnwUyimys style]].
* [[Film/JohnTuckermustDie Itou]] [[VisualNovel/SchoolDays Makoto]] [[http://www.youtube.com/watch?v=JhRfBdrVKDo MUST DIE!]]
* [[http://www.youtube.com/watch?v=SiBER4iVwCw This trailer]] for a ''VideoGame/PunchOut'' movie. If only they actually did the entire movie...
** From the same group, [[http://www.youtube.com/watch?v=SKBCcA9LJzk this trailer]] for a {{VideoGame/Contra}} movie. Could have been awesome if they made it real... So may ''Film/{{Predator}}'' references that you could believe they were the reason the sequel was made.
* ''WebVideo/PokemonApokelypse'' is a response to the "common trend of 'dark and gritty' [[ContinuityReboot reboots of popular franchises]]."
* The ultimate crossover: ''[[https://www.youtube.com/watch?v=iJSp2jNI7Co Goonies of the Caribbean: The Search for One-Eyed Willy]]'' (Mashup of ''Film/TheGoonies'' and ''Franchise/PiratesOfTheCaribbean'')
** How about ''[[http://www.youtube.com/watch?v=adEYyrpvvWo The Fugitive's Day Off]]'', (Mashup of ''Film/TheFugitive'' and ''Film/FerrisBuellersDayOff'')?
** Or even ''[[http://youtu.be/iRtNWGnBgAk No Country for Old Men in Black]]'' (Mashup of ''Film/NoCountryForOldMen'' and ''Film/MenInBlack'')? It becomes HilariousInHindsight as Creator/TommyLeeJones' ''No Country'' costar Creator/JoshBrolin would play young Agent K in ''Film/MenInBlack3''.
* Not only is there a live-action MyLittlePony [[http://www.youtube.com/watch?v=sXoYK4b_q24 movie]], but they go behind the scenes [[http://www.youtube.com/watch?v=SgqgAExJMyw too]].
* Another version of mash-ups uses the sound from one trailer and the footage from another trailer/movie/TV show. An excellent example would be [[http://www.youtube.com/watch?v=D1qihwMN0JM Toy Story Requiem]]: footage from ''WesternAnimation/ToyStory'' and ''WesternAnimation/ToyStory2'' with the sound from ''Requiem of a Dream''.
* [[http://www.youtube.com/watch?v=7AyizzX1Xis Cock and Load]] a ''Grindhouse'' style preview about a man who has his penis replaced with a shotgun and uses it to fight the mob. Must be seen to be believed.
* A trailer for the Nicholas Cage ''Film/TheWickerMan2006'' has been made as [[http://www.youtube.com/watch?v=v_mW8mBzmHo though it was a comedy]]. It is hilarious.
* There's also ''WebVideo/TheVelociPastor'', a fake [=grindhouse=] trailer about a priest [[http://www.youtube.com/watch?v=aDNzzhCpqxA who turns into a dinosaur]].
* A peculiar small subgenre are the ''Premakes'': using edited footage of mostly old movies, they try to recreate how a movie could have been if it was made a few decades earlier. Youtube user [[http://www.youtube.com/user/whoiseyevan Whoiseyevan]] has created the best examples, like WesternAnimation/{{Up}} [[http://www.youtube.com/watch?v=ml9hAN5km14 as a 1965 live-action Disney movie]], Film/{{The Avengers|2012}} [[http://www.youtube.com/watch?v=-fCTokuOU_E in 1952]] (before all team members except ComicBook/CaptainAmerica were even created), and Film/TheEmpireStrikesBack [[http://www.youtube.com/watch?v=KmTpOQrqoO0 in 1950]]. The latter is particularly good before it takes from several movies that inspired StarWars firsthand. There are a few more Premakes around but not as good as these.
* There's a trailer for [[http://www.youtube.com/watch?v=OboZbyLsNG0 Nico Nico All Stars]], based on memes from Website/NicoNicoDouga, which sadly doesn't exist.
* While he waits for his movie to even get into production, ComicBook/{{Deadpool}} can watch [[http://youtu.be/HInW6v9G3qs this fan trailer]]. If the real thing ever happens, it better be as good as that.
* A trailer for [[http://www.youtube.com/watch?v=vGn3nydV6sU Monopoly: The Movie]] based off of the [[TabletopGame/{{Monopoly}} board game]]
* The season two DVD for ''WebVideo/MarbleHornets'' features, as an extra, a [[http://www.youtube.com/watch?v=XJDJO2hc24A trailer]] for the titular student film.
* [[http://www.youtube.com/watch?v=putQn89TQzc The Twit Network]]: A spoof of Film/TheSocialNetwork, telling Twitter's history instead of Facebook's.
* [[http://www.youtube.com/watch?v=m0av4se_430 This]] fan-made trailer for a ''Series/DoctorWho''/''Series/{{Sherlock}}'' crossover episode. It looks freaking awesome, even if there is no possible chance of it ever being done for real.
* There's a trailer for ''[[http://www.youtube.com/watch?v=fPQVjJD7COY Pedobear: The Bed Intruder]]'' slated for release on February 31st, 2012.
* ''[[http://www.youtube.com/watch?v=6jPoCaG8Xvg Dawn Of Fire]]'', although it's actually supposed to be the opening titles of the (fake) movie rather than the trailer. The [[DreamTeam cast and crew]] alone may make you want to see the movie anyway.
* For years there was a fake IMDB page out there somewhere for what sounds like a truly dreadful InNameOnly film adaptation of Creator/ChinaMieville's ''Literature/PerdidoStreetStation'' that had every kind of AdaptationDecay imaginable. It had many Mieville fans absolutely furious until they noticed that it wasn't on an actual IMDB web address.
* WebVideo/LoadingReadyRun made a fake trailer for an action movie, [[http://www.escapistmagazine.com/videos/view/loadingreadyrun/6239-Seth-McDebit Seth McDebit:]] [[MundaneMadeAwesome Combat Accountant]].
* TheMagicSchoolBus: [[http://www.youtube.com/watch?v=Rce6HTFBaFg The Movie Trailer]] has over 500,000 views on YouTube and a lot of people wishing that ([[PoesLaw whether seriously or not]]) it could actually be made into a movie.
* [[http://www.youtube.com/watch?v=a7YZYt8v4lo And here's an impressive one for]] WesternAnimation/CaptainPlanetAndThePlaneteers.
* [[https://www.youtube.com/watch?v=k6tLOz_2Dsc Super Mario Legacy]], made with clips from various movies to create the concept of a sequel to [[Film/SuperMarioBros the 1993 Super Mario Bros movie]].
* This is the entire point of the [[http://www.youtube.com/user/GrittyReboots Gritty Reboots]] [=YouTube=] channel.
* The [[http://www.youtube.com/watch?v=sZHS6fHYlhQ 2009 trailer]] for the [[UnCanceled sixth]] ''Series/RaumschiffGamestar'' season looked authentic... right until the producers resumed publication of its successor series ''Die Redaktion'' half a year later.
* This [[https://www.youtube.com/watch?v=BkGaza1rPfQ Hey Arnold Trailer]] which is basically ''WesternAnimation/HeyArnold'' meets ''Film/FatalAttraction''.
* For a while now, there's been this fake trailer for a [[https://www.youtube.com/watch?v=pPHy2dTzPa8 Mega Man Movie]] that's a parody of the cheapest InNameOnly adaptions that only take a few select bits of the source material and plug them into what's otherwise a generic hollywood plot. Funnily enough, it actually looks pretty good and there are many comments claiming that they'd genuinely go see it.
* [[http://www.trailerwarsbellingham.org/ Trailer Wars]] is a bi-monthly film festival devoted entirely to this trope. Entries have included such things as [[https://www.youtube.com/watch?v=U4B9k_bMbWI PONG 3D]] and [[https://www.youtube.com/watch?v=nKv5-hQjT18 a film noir take on McGruff the Crime Dog]].
* [[https://www.youtube.com/watch?v=zdVIB0kNktc This mock opening]] for an ''Franchise/AceAttorney'' anime, made using the cutscenes from ''[[VisualNovel/PhoenixWrightAceAttorneyDualDestinies Dual Destinies]]''.
* [[http://www.youtube.com/watch?v=dNHb3lZobt0 This hilarious trailer]] for the fake "Ghost Tits" movie featuring Creator/OliviaMunn.

[[folder:Western Animation]]
* There was a trailer for a live action ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' movie on the Volume 1 DVD.
--> "We're pretty sure they made the movie, too, but are waiting until our birthday."
* ''WesternAnimation/FamilyGuy'' featured a trailer for ''Film/ThePassionOfTheChrist 2: [[KungFuJesus Crucify This]]''. That movie NEEDS to be made.
** ''Series/XPlay'' did a similar thing, but with less Chris Tucker and more straight badassery. See the scene at the beginning where Jesus pulls himself off the cross and USES THE NAILS IN HIS HANDS AS WEAPONS.
* ''[[http://www.youtube.com/watch?v=eGDxmerOTkg Meapless in Seattle]]'' was supposed to be a trailer for a fake episode for ''WesternAnimation/PhineasAndFerb'', until they made it into a real episode later on. That episode ended with ''another'' fake trailer for an episode called ''[[https://www.youtube.com/watch?v=QpIzC5hZ4-4 Meap Me in St. Louis]]''.
* ''WesternAnimation/DoraTheExplorer: [[http://www.youtube.com/watch?v=TnpTcrtsN3U The Search for the Infinity Orb]]'' Website/CollegeHumor is now following up and making Dora The Explorer and the Destiny Medallion as an actual Miniseries, because so many people demanded it.
* ''WesternAnimation/{{Daria}}: [[http://www.collegehumor.com/video/6904493/daria-movie-trailer-with-aubrey-plaza The High School Reunion]]''
* For AprilFoolsDay 2014, the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' crew put together brief tv spots for ''[[https://www.youtube.com/watch?v=S-DDF0q68kw Dragonfire]]'', a SpaceOpera starring a humanized Spike, and ''[[https://www.youtube.com/watch?v=bMglq5ZgYK4 My Biggest Pony]]'', which is exactly what it sounds like. April Fool's Day 2015 saw a trailer for ''[[https://www.youtube.com/watch?v=FUSekVMt0Zk Apple Bloomers]]'', an {{Animesque}} show featuring the Cutie Mark Crusaders as anthropomorphic pony {{Magical Girl Warrior}}s.

!!Unintended spoofs:

[[folder:Video Games]]
* The ad for ''VideoGame/TheLegendOfZeldaTheWindWaker'' was shown in theaters. It was so different from the style of the actual game that until the video started showing gameplay footage, some people have mistaken it for a trailer for a ''Zelda'' movie.
* Same could be said for the ''VideoGame/MechWarrior 3'' intro being shown in theaters. It practically could be considered a trailer for some kind of ''TabletopGame/BattleTech'' movie.

[[folder:Web Originals]]
* There is someone trying to make a [[http://www.youtube.com/watch?v=5Bj_oymzfzg Final Fight]] movie, though he just needs the budget apparently to make it work. From the looks of the trailer it looks like he could do it.

[[folder:Western Animation]]
* The excellent [[https://vimeo.com/11191780 ''Pyrats'' animation]] was a final project for an animation school in Paris. It will never be a movie, but it looks like a trailer (and people have reported that they would like to go and see it).


[[folder:Anime and Manga]]
* The last episode of ''Anime/ExcelSaga'' has one of these for ''Anime/PuniPuniPoemi''. And [[{{Defictionalization}} then...]]

[[folder:Films -- Live-Action]]
* The movie ''Film/ScaryMovie2'' has a trailer for ''Film/{{Amistad}} 2'', which some people believe is the funniest part of the whole movie.
* ''Film/CSATheConfederateStatesOfAmerica'' features, among its mock commercials, ads for fake TV shows, including ''Runaway'', an obvious parody of ''Series/{{COPS}}''.
** ''Leave It to Beulah'' is a [[SubvertedTrope subversion]]: [[AluminumChristmasTrees It uses actual footage from a]] RealLife [[ValuesDissonance show made in the 1950's.]]
* The Music/WeirdAlYankovic movie ''Film/{{UHF}}'' had trailers for ''[[Franchise/ConanTheBarbarian Conan the Librarian]]'' and ''Film/{{Gandhi}} 2''.

[[folder:Live-Action TV]]
* On ''Series/ThirtyRock'', Tracy Jordan once made a trailer for his proposed biopic of UsefulNotes/ThomasJefferson... with him playing all the parts. Highlights include Tracy as Jefferson proclaiming "Eat ''that'', King George!" as he finishes writing the Declaration of Independence and the narrator describing him as an "Academy Award watcher".
* ''Series/{{Supernatural}}'' has a trailer for "Hell Hazers II: The Reckoning" in the episode "Hollywood Babylon."
* ''Series/TheDailyShow'' advertises several fake products on a regular basis, including ''Jon'' magazine and the Daily Show Home Game. In 2003, they started airing joke trailers for a new spinoff called ''The Colbert Réport'' that had "already been cancelled". ''[[Series/TheColbertReport The Report]]'' premiered in 2005, and has been described as "the only show that [[{{Defictionalization}} started as a promo for itself]]".
* A ''Series/BillNyeTheScienceGuy'' episode on the Earth's Crust had a trailer for a kid cop show called "[[https://www.dailymotion.com/video/x2w8tvj Johnny Crust.]]"
* ''Series/HowIMetYourMother'' had one of these where a trailer for ''Film/TheWeddingBride'' was mentioned on the show and the full trailer was [[http://www.weddingbridemovie.com/ released online here.]] The movie describes [[spoiler:Ted's failed relationship with Stella however from the somewhat skewed mind of her ex-boyfriend, now-husband, Tony. Ted in one episode goes to see this movie more than once and, at one point, acts out something similar to it to is date while he is in the movie theatre.]]
* ''Series/StargateSG1'':
** The 100th episode, "Wormhole X-Treme!" took its name from a show based on the team, which the Air Force is letting go forward to give the SGC PlausibleDeniability (assuming it stays on the air). After the opening titles SG-1 and Hammond are sitting in the briefing room watching a trailer for the show.
** In the two-hundredth episode, titled "200," the team is giving advice on the production of a ''Wormhole X-Treme!'' movie adaptation. The opening to act four, which airs immediately after a commercial break and was intended to be mistaken for another commercial, [[http://www.youtube.com/watch?v=E2RWM65ZjL4 is a trailer for]] ''[[http://www.youtube.com/watch?v=E2RWM65ZjL4 Teal'c, P.I.]]'' Bonus points for ''actually getting [[Film/{{Shaft}} Isaac Hayes]]'' to do the narration.
* On the RealityShow ''Series/ScreamQueens2008'', one challenge each season had the contestants starring in a trailer for a fake {{camp}}y horror film in order to test their acting skills. The first season, it was for a movie about [[CatholicSchoolGirlsRule reform school girls]] [[CoolVersusAwesome fighting zombies]], while in the second, it was a [[WeirdWest vampire Western]].

* The video for [[http://www.youtube.com/watch?v=LrrGKR8Xii4 "Hang Me Up To Dry"]] by indie rock band Cold War Kids. It's filmed in black-and-white, set in a post-war (World War II?) era and revolves around the relationship of a pale-skinned brunette and a LoveableRogue. The fact that it mentions that this is the third installment of a nonexistent trilogy turns this into a ForegoneConclusion whenever you watch it again (and again, and again), but some fans desperately yearn for {{Defictionalization}}.

* ''The Creator/ReducedShakespeareCompany Radio Show'' has an audio trailer for a SophisticatedAsHell movie version of ''Othello'' ("He was tough! He was black! He was jealous as hell!"), starring Mr. T ("I pity the fool who messes with Desdemona!")

* ''[[http://www.leastlikely.com/ The Least Likely]]'', Kelly Hu's project for CAUSE, made in an effort to get Asian-Americans to become more politically active and less apathetic (the name comes from the fact that Asians are the racial group that is least likely to vote each year, with only about one-third doing so). Rumors of an actual movie to go with the trailer still circulate.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'' and ''WesternAnimation/TheCritic'' are full of them.
** ''The Simpsons'' in particular had a CouchGag take the form of a movie trailer for "The Couch", which dramatizes [[MundaneMadeAwesome the Simpson family sitting on the couch]]. It was featured on the episode "A Test Before Trying".
* ''WesternAnimation/TheBoondocks'' episode "...Or Die Trying" opens with a trailer for ''[[https://www.youtube.com/watch?v=CORwMq9MG-c Soul Plane 2: The Blackjacking]]'', a fictional sequel to ''Film/SoulPlane'' that only exists in-universe. The episode itself is about the characters sneaking into a theater to watch the film.
* ''WesternAnimation/FostersHomeForImaginaryFriends'' "One False Movie" can be explained by both Bloo's overwhelming ego and the RuleOfFunny, as the 'trailer' seems to be the opening part of the film it's pimping.
