* This is avoided in the opening of ''Film/StarTrekIIITheSearchForSpock''...but there is an extra long pause between Creator/WilliamShatner's credit and [=DeForest=] Kelley's where Nimoy's name would normally appear.

** During the making of featurette for ''[[Manga/DeathNote Death Note: The Last Name]]'', key scenes from the film were shown and it was revealed that the film was a two-parter.

* The second intro for ''WesternAnimation/StevenUniverse'' shows Connie wielding Rose's sword, spoiling that she'd be trained as a sword fighter (which happens in the intro's debut episode) and that it would become her usually weapon (which happens ten episodes later).

* The second intro for ''WesternAnimation/StevenUniverse'' shows Connie wielding Rose's sword, spoiling that she'd be trained as a sword fighter (which happens in the intro's debut episode) and spoiling that she'd eventually have [[ChekhovsGun that sword]] (which happens ten episodes later).

* ''[[WesternAnimation/TotalDrama Total Drama Action]]''
** The theme song features Courtney, who came back halfway through to the surprise of the castmates and (maybe) Chris. However, the flipbook itself had no intention of this ever being a spoiler.
** The leaked theme song for ''World Tour'' also FINALLY settled the issue of Ezekiel's participation in the season or not. He's in. For now.

** The opening of ''WesternAnimation/TeenageMutantNinjaTurtles2003'' spoils that Darius Dun, initially a minor supporting character, is the BigBad (he is seen looming over all the other villains).

[[Administrivia/InternalSubtrope A variation]] is where an [[TheUnseen unseen character]] or actor is [[{{TheFaceless}} kept hidden]] [[ToBeContinued until the next installment]], yet credited in the ClosingCredits. Another variation is where vaguely famous names appear in the credits, so [[NarrowedItDownToTheGuyIRecognize you can guess automatically that they're going to be fairly prominent in the episode before they even show up]]. In series with recurring characters that are not normally in the credits or a [[TheBusCameBack cameo from someone who left the show]] this can indicate their eventual presence in an episode ruining their unexpected entrance. These variants are often {{Enforced|Trope}} by the certain rules of Actor UsefulNotes/{{Unions|InHollywood}},[[note]]specifically, who can appear where in the credits[[/note]] [[http://www.midwinter.com/lurk/guide/098.html as noted by]] Creator/JMichaelStraczynski. DeadStarWalking can be either a straight-playing or an aversion of this subtrope, depending on how it's presented.

* Films shown as Fathom Events often like to put in making of featurettes before the movie, which often contain clips or information that can blow certain plot details for people seeing the films for the first time. [[https://www.youtube.com/watch?v=WX5Jnd36iJw This video mentions the following three examples]]:

** When ''Film/{{Rambo}}'' was shown in 2008, Sylvester Stalone showed the alternate ending of the first movie where Rambo died during the making-of documentary. The Rambo sequels were also mentioned in the preshow.

** An interview that played before the Insider Access to ''WesternAnimation/InsideOut'' event spoiled Bing Bong's death when talking about how his voice actor cried saying "Take her to the moon for me...okay?". What's even worse is that the '''trailers''' for the event spoiled some parts of the end of the film, including the scene where Joy runs through Imagination Land, the scene where Anger puts in the idea for Riley to run away and the scene where Joy and Sadness splat onto the window of Headquarters after Fear says "I wish Joy was here!"
** Thankfully, this is less frequent as it was before now, possibly due to the complaints they've received. Many events nowadays either put the bonus content after the movie (such as Doctor Who and The Iron Giant), use clips that don't spoil much of the movie (such as TeamHotWheelsOriginOfAwesome, which used clips from the first 20 minutes, which were already available for free on YouTube), use no clips at all (Some examples include the 2015 showings of The Wizard of Oz and Film/{{Grease}}, which had introductions by TCM hosts that don't spoil the film. For example, the Wizard of Oz screening had a brief explanation of how the film found success when it was shown on TV, since it didn't do well in theaters when it first came out) or interview the cast (such as One Direction: Where We Are and DragonBallZResurrectionF[[note]] While not mainly distributed by Fathom Events, but rather Funimation Films, only a select number of theaters had the film distributed by Fathom.[[/note]]).

** An alternate opening narration for the first episode averts this trope, as it gives more information on the war and the Avatar but doesn't mention Aang. Before long, though, the opposite problem develops, as the narration becomes wildly outdated by the end of season 1.

[[InternalSubtrope A variation]] is where vaguely famous names appear in the credits, so [[NarrowedItDownToTheGuyIRecognize you can guess automatically that they're going to be fairly prominent in the episode before they even show up]]. In series with recurring characters that are not normally in the credits or a [[TheBusCameBack cameo from someone who left the show]] this can indicate their eventual presence in an episode ruining their unexpected entrance.

DeadStarWalking can be either a straight-playing or an aversion of this subtrope, depending on how it's presented.

* The first season of ''WesternAnimation/JusticeLeagueUnlimited'' showed clips from the current episode during its opening, occasionally spoiling plot points.
* The opening credits for "WesternAnimation/JusticeLeague" would show (sometimes spoilerific) scenes from that particular episode.

* ''WesternAnimation/LegionOfSuperheroes'' pilot 'Man Of Tomorrow' had spoilers in the opening credits, showing Timber Wolf who wouldn't be making an appearance until the next episode.

* EvolvingCredits: updating the existing opening as events transpire in-series
* TitleSequenceReplacement: creating new openings at various points in the series,

* This is avoided in the opening of ''Film/StarTrekIIITheSearchForSpock''...but there is an extra long pause between WilliamShatner's credit and [=DeForest=] Kelley's where Nimoy's name would normally appear.

* In ''WesternAnimation/ReBoot'' every four episodes of season 3 had an opening sequence using clips from those four episodes. Naturally plot developments like Enzo's TimeSkip, the Saucy Mare's web armor, and Mainframe in ruins are spoiled. Averted with the {{Toonami}} broadcast, which replaced those openings with customized ones.

An overlap with ForegoneConclusion at times happens. See also FirstEpisodeSpoiler, which can often fall prey to this, though that can be averted with any of the above methods or just using a TitleOnlyOpening for that episode.

Contrast NotNamedInOpeningCredits when the credits omit an actor's name and maintain the surprise.

!!'''Since this is a spoiler trope, there will be unmarked spoilers below.'''

** The intro also depicts Cinder in an ObviouslyEvil fashion- surrounded by flames and minions- which is odd, as she only appears in the season finale's [[TheStinger stinger]].

* The opening narration of ''Film/{{Hop}}'' spoils the fact that the main human character becomes the first human easter bunny. This concept isn't introduced untill a little before the climax, after a movie of basically nothing happening.

** Thankfully, this is less frequent as it was before now, possibly due to the complaints they've received.

* In the film ''Film/{{Horsemen}}'' (starring Dennis Quaid), Ziyi Zhang has second billing in the opening credits. Even if you didn't recognize the name, the fact that she's the only Asian actor in the movie gives away the fact that her character is more than she seems to be when she is first introduced.

* ''WesternAnimation/KimPossible'': Lord Monty a.k.a. Monkey Fist appears in the opening theme from the very first episode onwards, however his first appearance was not until episode 13, where it was written as if Monty turning out to be the bad guy was a big twist.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' not only gives away its central philosophy in the very title (notable since Part 1 of the two-part series premiere was a {{deconstruction}} of [[MyLittlePony the show's parent franchise]] and [[GirlShowGhetto other such "little girl shows"]]), but summarizes the main protagonist's [[CharacterDevelopment character arc]] over the course of said premiere in the first few lines of its theme song.

* ''WesternAnimation/AvatarTheLastAirbender'':

* The theme song for ''[[WesternAnimation/TotalDrama Total Drama Action]]'' features Courtney, who came back halfway through to the surprise of the castmates and (maybe) Chris. However, the flipbook itself had no intention of this ever being a spoiler.

* The opening of ''WesternAnimation/TeenageMutantNinjaTurtles2003'' spoils that Darius Dun, initially a minor supporting character, is the BigBad (he is seen looming over all the other villains).

* An episode of the animated ''WesternAnimation/YoungJustice'' series has the team helped out by an arrow fired from the shadows. When they confront Green Arrow and accuse him of babysitting them and he proves it wasn't his arrow, they assume his sidekick, Speedy, is ready to join the team after storming out in the pilot. Yeah ... or maybe it's the female archer who appears in the opening credits of the show as a team member despite having not appeared in the actual show yet at that point.
** The team isn´t completely assembled in story before episode 6 but the intro shows the whole team since episode 1.

* ''WesternAnimation/JackieChanAdventures'':
