** ''WesternAnimation/ShrekTheThird'''s merchandise spoiled the birth of the Shreklings (Shrek and Fiona's children) and the dragon/donkey hybrids (Donkey and Dragon's children), as well as the [[DamselInDistress Distressed Damsel]] [[EverythingsBetterWithPrincesses princesses]] going ActionGirl.

** A fan-edited trailer parodies this. The video makes some {{Retraux}} attempts at emulating an ad from TheNineties, with a love ballad playing in the background, some idents from Disney's VHS tapes serving as bookends, and a clip revealing some major points about the climax (the scene in which a freezing Anna tries to stop Hans from killing Elsa) appearing before the title card.

*** [[https://www.ispot.tv/ad/AS8q/subway-finding-dory-peek-into-dorys-world This Subway commercial for kids' meals based off the film]] uses clips that spoil some major plotlines in the movie, including the fact that Marlin and Nemo wait for Dory in the tanks that are going on the truck to Cleveland.

** If you can believe it, ''the same convention'' also spoiled that Deathlocket, Hazmat, Anachronism, Cammi, and Cullen Bloodstone would survive when Marvel announced the SpiritualSuccessor, ''ComicBook/AvengersUndercover''.

** ''Toy Story 3'' had trailers that spoiled that the new toys were the villains. And while they never explicitly stated who the BigBad was, many viewers were able to tell just from what was shown (and if not that, then from the other marketing). In the later trailers it almost revealed that the real plot was an [[MoodWhiplash emotional rollercoaster.]]

* ''Disney/TheLionKing'''s trailer spoils most of the plot. Movie posters show Mufasa's ghost as well.

* The toy commercials for the ''Toys/{{Bionicle}}'''s Glatorian Legends line of figures showed glimpses of the then-upcoming movie, ''The Legend Reborn''. Among them, the very shot of the four heroes unleashing the final blast at the Skrall and Bone Hunter army, from the end of the climax! Website promos also spoiled Metus' transformation into a snake, thereby revealing that he was to be the traitor. This was also spoiled by the site's behind-the-scenes videos, which showed the actors recording lines -- fans have narrowed the identity of the traitor down to Berix and Metus, and then the clips showed Berix's VA talking to the traitor.

** The DVD trailer for ''WesternAnimation/KungFuPanda2'' completely spoiled the fact that Po's biological father, and several other pandas, are still alive, which wasn't revealed until the last few seconds of the film.

** Official trailers show some spoileriffic clips, such as Elsa bringing back summer and saving Olaf from melting. A more subtle example is Elsa giving Anna a hug, when Elsa had previously been too scared to approach, much less touch, Anna. It's also apparent on closer examination that this happens after Anna's aforementioned HeroicSacrifice frees herself from the curse.
* One preview of ''WesternAnimation/TheLegoMovie'' showed bits from Emmet's vision, including a live-acted human hand. Also, Bad Cop's fate was revealed by his toy, released prior to the movie. The LEGO sets actually gave away many details, such as Bad Cop's parents getting frozen in glue or Uni-Kitty disguising herself as Business-Kitty, but not always the exact interpretation of the scenes.

* The original BMG Video trailer for ''[[WesternAnimation/MagicAdventuresOfMumfie Mumfie's Quest]]'' shows Mr. and Mrs. Admiral being reunited, Whale being freed from a net by the electric eels and part of the scene where Secretary of Night gets turned into stone by the Cloak of Dreams.
* The trailers for ''WesternAnimation/TheThiefAndTheCobbler'' had clearly shown the entire plot of the film which included the three golden balls being stolen from the kingdom, the climatic battle with the main villain One-Eye and Tak and Princess Yum-Yum getting married at the end of the film.

* ''WesternAnimation/{{Megamind}}'' probably had one of the worst offending trailers, in which it revealed that Metro Man was ''not'' dead and had simply given up superheroing. The entire film revolved around the fact that Megamind was trying to cope with having killed Metro Man.

* ''WesternAnimation/{{Coraline}}''. The trailer shows the scene where the Other Mother gives Coraline the buttons and sewing needles.

** The trailer for ''WesternAnimation/{{Up}}'' spoiled that Charles Muntz is the villain.

* ''Disney/MeetTheRobinsons'' had a trailer that showed the future Lewis in a group with the Robinson family, with his arm around Franny from one of the final scenes in the movie, making the big reveal completely predictable.

* A home video trailer for ''WesternAnimation/TitanAE'' showed the entire movie, start to finish, in order, including the final scenes of a new Earth being formed and the lead characters on it. As a result, some didn't bother to see the movie. Indeed, the movie didn't do well in theaters; this might have been a factor.

* The trailer for Creator/DonBluth's ''WesternAnimation/{{Anastasia}}'' spoils the fact that Anya ''is'' Anastasia, and then shows her in the palace, in formal attire, being addressed as "the princess" and "Your Highness." The previous spoiler isn't so bad, since it's to be expected, but the latter is a ''big'' spoiler.

* The trailers for ''WesternAnimation/HoodwinkedTooHoodVersusEvil'' stress the fact that Red and co. are trying to save two innocent kids from a wicked witch. Save for the one which shows said "innocent" children with [[SlasherSmile creepy]] [[NightmareFuel grins]] saying: "[[EnfantTerrible You've]] [[CreepyChild been hoodwinked!]] [[TitleDrop Too!]]"

** The DVD trailer for ''WesternAnimation/KungFuPanda3'' spoils literally almost the entire movie, including Kai's destruction of the Jade Palace, Po training of the panda village to fight against Kai, and the final battle in the Spirit Realm.

* This ''Disney/{{Mulan}}'' [[https://www.youtube.com/watch?v=wAbGAkkOgcM trailer]] in which it shows the Emperor's big speech at the end, which in turn gives away big chunks of the movie. It even shows the scene with her turning around and all of China bowing to her.
* The TV commercials for ''WesternAnimation/{{Nine}}'' try their best to hide things by cutting rapidly from scene to scene, but they still manage to spoil 2's funeral, the destruction of the Fabrication Machine, the Cat Beast's death, and several of the dolls having their souls sucked out by the talisman.

* Near the end of the second trailer for ''WesternAnimation/TheBookOfLife'', it happens in a brief second but one can see the Sanchez ancestors near the climax.

* The trailers for ''Disney/BigHero6'' never really tried to hide the fact that Tadashi dies, although it happens early in the film. UK advertising reveals that Hiro wants to kill Yokai.

* [[https://www.youtube.com/watch?v=MZKazzZYTFo&t=6s The trailer]] for ''WesternAnimation/AnAmericanTail: Fievel Goes West'' is a special case. It didn't spoil itself so much, but the fact that the trailer of the sequel movie (which begins with the ending scene of the previous film, with Fievel riding a pigeon with his sister and asking if he could see more of America) was included at the beginning of every VHS release of the first movie after 1991 meant that it revealed the ending of ''An American Tail'' before the movie even started, spoiling that Fievel finds his family for anyone who was watching the movie for the first time.

*** Some of the American trailers spoil the movie as well. Two notable examples were the clip where Joy rides in Bing Bong's rocket to the top and we can clearly see that he is not in it, and the scene where Joy and Sadness return to Headquarters.

*** Later trailers and commercials for the film spoil the scene where [[spoiler:Hank gets poked by a kid and inks in the touch pond, causing the kids in the area to run away.]] It got to the point where said clip was shown during shows where Ed O'Neil, Hank's voice actor, was interviewed such ''Entertainment Tonight''.
*** [[https://m.youtube.com/watch?v=ByqIiRUuoQ0 The clip used to introduce Hank]] in this April Fool's prank is part of the scene where Dory reaches her old home at the Open Ocean exhibit.

** Then we got ''WesternAnimation/TheGoodDinosaur'''s case, which takes this UpToEleven. Most of the trailers spoil [[spoiler:Poppa's death,]] Arlo's friendship to Spot, the meeting of Forrest Woodbush, Arlo helping the cowboy T-Rexes, Arlo encounters the main villian, Thunderclap and also the climax. In short, the trailers just showed you the entire movie. This could be one of the reasons why the film didn't perform so well at the box office.

* A TV spot for ''Franchise/WallaceAndGromit'': ''WesternAnimation/TheCurseOfTheWereRabbit'' spoiled that the were-rabbit is [[spoiler:Wallace,]] showing fuzzy fur popping out of [[spoiler:his trademark sweater-vest.]]] It even had the announcer say "What started as a little mistake became a ''big'' problem" over scenes of the mind-manipulator accident and said transformation scene.

** The trailer for ''WesternAnimation/BartokTheMagnificent'' spoils Ludmilla's transformation into a dragon.

* ''WesternAnimation/HowToTrainYourDragon2''[='=]s trailer takes no issue with spoiling TheReveal of Hiccup's mother.

* A TV spot for ''Franchise/WallaceAndGromit'': ''WesternAnimation/TheCurseOfTheWereRabbit'' spoiled that the were-rabbit is Wallace, showing fuzzy fur popping out of his trademark sweater-vest. It even had the announcer say "What started as a little mistake became a ''big'' problem" over scenes of the mind-manipulator accident and said transformation scene.

*** Later trailers and commercials for the film spoil the scene where Hank gets poked by a kid and inks in the touch pond, causing the kids in the area to run away. It got to the point where said clip was shown during shows where Ed O'Neil, Hank's voice actor, was interviewed such ''Entertainment Tonight''.

*** [[https://www.youtube.com/watch?v=bnTHJM7ct88 The film's Japanese trailer]] shows the otters bringing Dory into the truck bound for Cleveland as well as Destiny jumping out of her enclosure, both from the climax of the film.
** Then we got ''WesternAnimation/TheGoodDinosaur'''s case, which takes this UpToEleven. Most of the trailers spoil Poppa's death, Arlo's friendship to Spot, the meeting of Forrest Woodbush, Arlo helping the cowboy T-Rexes, Arlo encounters the main villian, Thunderclap and also the climax. In short, the trailers just showed you the entire movie. This could be one of the reasons why the film didn't perform so well at the box office.
* One of the trailers for ''WesternAnimation/TheSpongebobMovieSpongeOutOfWater'' clearly shows Plankton as Plank-Ton.
* A ''WesternAnimation/SausageParty'' trailer spoils Carl's death.

* ''WesternAnimation/{{Paranorman}}'':
** The trailer spoils nearly every joke, even if it does not spoil the plot for the most part.
** Even worse, the Japanese trailer did spoil the plot.

* The UK advertising for ''Disney/BigHero6'' reveals that Hiro wants to kill Yokai.

* ''ComicBook/HeroesReborn'' was advertised during ''ComicBook/{{Onslaught}}'', revealing well before the ''Onslaught: Marvel Universe'' one-shot that concluded the story that Franchise/CaptainAmerica, Franchise/IronMan, ComicBook/TheMightyThor, [[ComicBook/IncredibleHulk the Bruce Banner]] [[LiteralSplitPersonality personality]], [[ComicBook/AntMan Giant-Man]], ComicBook/TheWasp, ComicBook/{{Hawkeye}}, the ComicBook/ScarletWitch, ComicBook/TheVision, ComicBook/TheFalcon, the ComicBook/BlackPanther, Crystal of ComicBook/TheInhumans, the Franichse/FantasticFour, and ComicBook/DoctorDoom would ([[ComicBookDEath seemingly]]) fall in battle.

* ''ComicBook/HeroesReborn'' was advertised during ''ComicBook/{{Onslaught}}'', revealing that Franchise/CaptainAmerica, Franchise/IronMan, ComicBook/TheMightyThor, Franchise/TheAvengers, and the Franichse/FantasticFour would ([[ComicBookDEath seemingly]]) fall in battle.

* A common problem with comic books is that solicitations for future issues of a series can spoil not only the current story line but future plots as well. A common way publishers get around this problem is to keep their solicitations as vague as possible and release cover art that's either unfinished, a variant or even edited to remove potential spoilers.
* It is standard operating procedure for Creator/{{Marvel|Comics}}, Creator/{{DC|Comics}}, and Franchise/ArchieComics to spoil major events well in advance in order to generate interest and get retailers to place larger orders.

** If you can believe it, ''the same convention'' also spoiled that Deathlocket, Hazmat, Anachronism, Cammi, and Cullen Bloodstone would survive when Marvel announced the SpiritualSuccessor, ''Avengers Undercover''.

* ''ComicBook/SecretWars2015'' was marketed on the premise that the MarvelUniverse was being KilledOffForReal, and that nobody was sure what new universe would be taking it's place. The subsequent sneak peeks for books like ''All-New, All-Different Avengers'' and ''Invincible Iron Man'', coupled with WordOfGod confirmation that books like ''ComicBook/MsMarvel2014'' would continue, more or less confirmed that the "new" Marvel Universe was essentially the same one as the old one.

* A few weeks before ''ComicBook/ForeverEvil'' kicked off, DC announced that ''Trinity War'' would see the Crime Syndicate of Earth 3 removing the Justice Leagues from the picture & taking over the Earth, with ComicBook/LexLuthor's alliance of villains fighting back.
* Marvel basically confirmed that ''Hunger'' would end with a FailureIsTheOnlyOption scenario by revealing that their next CrisisCrossover for the [[ComicBook/UltimateMarvel Ultimate]] line, ''[[Comicbook/CataclysmTheUltimatesLastStand Cataclysm]]'', would see ComicBook/{{Galactus}} reaching Earth and beginning his assault. To those unaware, the entire premise of ''Hunger'' was that ComicBook/SilverSurfer and Rick Jones were desperately trying to stop Galactus ''before'' he could get to Earth.
* A plot point in ''Comicbook/OriginalSin'' involved ComicBook/NickFury recruiting Comicbook/BlackPanther, the [[ComicBook/BuckyBarnes Winter Soldier]], Gamora, ComicBook/DoctorStrange, Comicbook/EmmaFrost, [[ComicBook/AntMan Scott Lang]], and Comicbook/ThePunisher for a mysterious purpose. Eventually, it was revealed that Fury was dying of old age, and needed one of them to be his successor. Marvel treated the news as TheReveal and made it seem like a serious "Who will Fury choose?!" {{Cliffhanger}}, despite the fact that they'd ''already revealed'' that Fury's successor would be the Winter Soldier several weeks earlier.
* The same basic thing happened in Rick Remender's ''ComicBook/CaptainAmerica'' run. Marvel revealed on ''Series/TheColbertReport'' that [[ComicBook/TheFalcon Sam Wilson]] would be the [[LegacyCharacter new]] Captain America, yet still treated it like a big secret in-story, and even tried to make it seem like Sam had died pulling a HeroicSacrifice just before he emerged as the new Cap.
** This was then {{Lampshaded}} when Sam was finally unveiled onscreen to his Avengers teammates. He immediately says that there is no drama in this reveal, and that [[LeaningOnTheFourthWall everyone]] ''must'' have known by now that he was going to be the new Cap.

* This was pretty much averted with ''ComicBook/BatmanEndgame'', as the none of the early covers were revealed and all the solicitations just said was that it was an important story and one would have to read the first issue to find out that [[spoiler: the Joker was making his post-''ComicBook/DeathOfTheFamily'' return.]]

* The summary of ThirtyHs is basically a summary of the events of the first few chapters.

* ''WesternAnimation/{{Shrek}}'':
** The nature of Puss N Boots (a cute little kitty who just happens to be a mercenary) is clearly meant to be a comedic twist, but the trailers for ''Shrek 2'' practically made it the main selling point.
** ''Shrek the Third'''s merchandise spoiled the birth of the Shreklings (Shrek and Fiona's children) and the dragon/donkey hybrids (Donkey and Dragon's children), as well as the DistressedDamsel [[EverythingsBetterWithPrincesses princesses]] going ActionGirl.

* Watch any of the commercials for ''WesternAnimation/ThePowerpuffGirls Movie'' and you've watched the whole thing (and this could've been why the movie didn't do so well). It also doesn't help that Cartoon Network aired these commercials on practically every commercial break when the movie came out.
* A TV spot for ''WesternAnimation/WallaceAndGromit'': ''WesternAnimation/TheCurseOfTheWereRabbit'' spoiled that the were-rabbit is Wallace, showing fuzzy fur popping out of his trademark sweater-vest. It even had the announcer say "What started as a little mistake became a ''big'' problem" over scenes of the mind-manipulator accident and said transformation scene.

* One of the trailers for ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'' clearly shows Plankton as Plank-Ton.
** [[https://www.youtube.com/watch?v=wJo-a9lI_us This commercial]] is composed of clips from the climax from the film.

* The trailer for ''WesternAnimation/{{Trolls}}'' advertises new songs by Justin Timberlake, who voices a character that does not sing at the beginning of the film. What are the chances that will change by the end?

* [[https://www.youtube.com/watch?v=pazuQ--rYls This trailer]] for Theatre/{{Elisabeth}} blatantly shows the Mayerling Waltz. (Sisi's death doesn't count, because Lucheni says "I killed her because she wanted to die," some several seconds into the video.) It's not much of a spoiler for German/Austrian audiences, or people familiar with that era, because both [[spoiler: the Empress' ImpaledWithExtremePrejudice and the Crown Prince's MurderSuicide]] is well-known. Outside of that, though, viewers caught unaware (especially those who have issues with viewing gun violence and suicide) are in for a potential shock. The trailer narrator even says,[[{{Lampshading}} "It's more than a show, it's history."]]

* The trailer for Website/ThatGuyWithTheGlasses' two-year anniversary special ''WebVideo/{{Kickassia}}'' had [[WebVideo/TheSpoonyExperiment Spoony]] shouting "Oh my gosh! It's 3D Lee!"
** And the final trailer for their fourth anniversary special ''WebVideo/ToBoldlyFlee'' spoiled WebVideo/TheNostalgiaCritic absorbing the PlotHole.
* More like "the preview always spoils", unless the [=YouTube=] user has found a way to muck with the video thumbnail of a movie, [=YouTube=] will default it to the middle of the movie. If it's say, for a race and the course is known, you can tell at least midway who's winning.
** A variation: if you're going to watch a comedy video, you'd do well to avoid looking at the top comments. They almost always contain the funniest jokes.

* [[https://www.youtube.com/watch?v=pazuQ--rYls This trailer]] for Theatre/{{Elisabeth}} blatantly shows the Mayerling Waltz. (Sisi's death doesn't count, because Lucheni says "I killed her because she wanted to die," some several seconds into the video.)

[[{{Lampshading}} "It's more than a show, it's history."]]

There is also the matter of ''context''. An action movie, for example, may preview a random fight scene between two characters, but when you actually see the movie itself and realize that the other dude the hero was fighting happened to be his best friend in the beginning (which may or not have also been part of that trailer), you realize ''in retrospect'' that the trailer's fight scene was actually a {{foreshadowing}} or ChekhovsGun about the betrayal that occurs later.

** They did the same thing with [[Comicbook/UltimateSpiderMan Miles Morales]]' identity, which was revealed to mainstream news outlets before the book had even hit stands. The ensuing controversy over a black Spider-Man was covered on everything ranging from Fox News to TheDailyShow.

* The same basic thing happened in Rick Remender's ''ComicBook/CaptainAmerica'' run. Marvel revealed on ''TheColbertReport'' that [[ComicBook/TheFalcon Sam Wilson]] would be the [[LegacyCharacter new]] Captain America, yet still treated it like a big secret in-story, and even tried to make it seem like Sam had died pulling a HeroicSacrifice just before he emerged as the new Cap.

** [[https://www.youtube.com/watch?v=wJo-a9lI_us This commercial]] is comprised of clips from the climax from the film.

* The trailer for ''WesternAnimation/AnAmericanTail Fievel Goes West'' is a special case. It didn't spoil itself so much, but the fact that the trailer of the sequel movie (beginning with the ending scene of the previous film, with Fievel riding a pigeon with his sister and asking if he could see more of America) was included at the beginning of every VHS release of the first movie after 1991 meant that it revealed the ending of ''An American Tail'' before the movie even started, spoiling that Fievel finds his family for anyone who was watching the movie for the first time.

* The trailers for the sequel to ''WesternAnimation/{{Hoodwinked}}'' stress the fact that Red and co. are trying to save two innocent kids from a wicked witch. Save for the one which shows said "innocent" children with [[SlasherSmile creepy]] [[NightmareFuel grins]] saying: "[[EnfantTerrible You've]] [[CreepyChild been hoodwinked!]] [[TitleDrop Too!]]"

* A home video trailer for ''WesternAnimation/TitanAE'' showed the entire movie, start to finish, in order, including the final scenes of a new Earth being formed and the lead characters on it. Why bother to see the movie? Indeed, the movie didn't do well in theaters; this might have been a factor.

* The trailer for Creator/DonBluth's ''WesternAnimation/{{Anastasia}}'' spoils the fact that Anya ''is'' Anastasia, and then shows her in the palace, in formal attire, being addressed as "the princess" and "Your Highness." The previous spoiler isn't so bad, since it's to be expected, but did they have to show she's recognized as such?

* Watch ANY of the commercials for ''WesternAnimation/ThePowerpuffGirls Movie'' and you've watched the whole thing (and this could've been why the movie didn't do so well). It also doesn't help that Cartoon Network aired these commercials on practically every commercial break when the movie came out.

* The TV commercials for ''WesternAnimation/{{Nine}}'' try their best to hide things by cutting rapidly from scene to scene, but they still manage to spoil 2's funeral, the destruction of the Fabrication Machine, the Cat Beast's death, and several of the dolls having their souls sucked out by the talisman. Geeze!

* Whoo-boy, the trailers for recent {{Creator/Pixar}} films are not that very good to hide its own plots from its entirety, such as:
** ''WesternAnimation/InsideOut'': As far as the film goes, whatever you do, if you don't want to be spoiled, ''stay away from the Japanese trailers!''

** Then we got ''WesternAnimation/TheGoodDinosaur'''s case. And oh boy, where do we begin. Most of the trailers spoil Poppa's death, Arlo's friendship to Spot, the meeting of Forrest Woodbush, Arlo helping the cowboy T-Rexes, Arlo encounters the main villian, Thunderclap and also the climax. In short, the trailers just showed you the entire movie. This could be one of the reasons why the film didn't perform so well at the box office.

-->'''Shadow Labrys:''' Labrys is a robot? Heavens to murgatroyd. What a complete and utter surprise...or it mighta been if it hadn't been given away on the ***ing box art...

* As far as ''WesternAnimation/InsideOut'' goes, whatever you do, if you don't want to be spoiled, ''stay away from the Japanese trailers!''
** Some of the American trailers spoil the movie as well. Two notable examples were the clip where Joy rides in Bing Bong's rocket to the top and we can clearly see that he is not in it, and the scene where Joy and Sadness return to Headquarters.

* ''WesternAnimation/FindingDory'' had a bad case of this:
** Later trailers and commercials for the film spoil the scene where Hank gets poked by a kid and inks in the touch pond, causing the kids in the area to run away. It got to the point where said clip was shown during shows where Ed O'Neil, Hank's voice actor, was interviewed such ''Entertainment Tonight''.
** [[https://m.youtube.com/watch?v=ByqIiRUuoQ0 The clip used to introduce Hank]] in this April Fool's prank is part of the scene where Dory reaches her old home at the Open Ocean exhibit.
** [[https://www.ispot.tv/ad/AS8q/subway-finding-dory-peek-into-dorys-world This Subway commercial for kids' meals based off the film]] uses clips that spoil some major plotlines in the movie, including the fact that Marlin and Nemo wait for Dory in the tanks that are going on the truck to Cleveland.
** [[https://www.youtube.com/watch?v=bnTHJM7ct88 The film's Japanese trailer]] shows the otters bringing Dory into the truck bound for Cleveland as well as Destiny jumping out of her enclosure, both from the climax of the film.

* Oh boy, where to start. Most of the trailers for ''WesternAnimation/TheGoodDinosaur'' spoil Poppa's death, Arlo's friendship to Spot, the meeting of Forrest Woodbush, Arlo helping the cowboy T-Rexes, Arlo encounters the main villian, Thunderclap and also the climax. In short, the trailers just showed you the entire movie. This could be one of the reasons why the film didn't perform so well at the box office.
