** ''Film/SpiderManHomecoming'' ended with Adrian Toomes aka The Vulture aware that Peter Parker is Spider-Man but refusing to disclose his identity out of gratitude for Peter saving the lives of him and his daughter. In TheStinger one of Vulture's accomplices, Mac Gargan makes it clear he doesn't buy Vulture's claims of not knowing Spider-Man's identity and will pry the information out of him to get vengeance. Neither of the film's sequels features Toomes or Gargan and the end of ''Film/SpiderManNoWayHome'' has [[spoiler: all memories of Peter Parker being erased from the universe, making it impossible for the plot thread to resume]]. However, it becomes subverted when [[spoiler:he turned out to have been teleported into Film/SonysSpiderManUniverse by the same spell that erased Spider-Man's identity, as shown in [[Film/Morbius2022]], and seeks to form the ComicBook/SinisterSix with him]].

** ''Film/TheIncredibleHulk'':
*** This movie's [[StillbornFranchise poor box-office returns]] created a big one involving [[MadScientist Dr. Samuel Sterns]] and his StartOfDarkness. Though the studio was able to continue Bruce Banner's character arc with his appearance in ''Film/{{The Avengers|2012}}'', the lack of direct sequels to ''The Incredible Hulk'' meant that we never got to see the fallout from [[spoiler:Sterns using Banner's gamma-irradiated blood to turn himself into the Leader]]. This plot thread was [[AllThereInTheManual eventually continued]] in the ''Fury's Big Week'' comic that was released as a prequel to ''The Avengers''. In it, [[spoiler:Sterns uses his new abilities to attack Black Widow, only to end up knocked out and taken into custody by ComicBook/{{SHIELD}}.]]
*** The even bigger plot thread was TheStinger that showed Thunderbolt Ross partnering with [[Film/IronMan Tony Stark]] to take down the Hulk. This was never mentioned in any of the subsequent films. [[OnceMoreWithClarity This was explained]] in the short film ''Film/TheConsultant''; S.H.I.E.L.D. sent Stark as a patsy to ruin the relationship with Ross after the World Security Council ordered Fury to add the Abomination to the roster of the Avengers.
** ''Film/CaptainAmericaTheWinterSoldier'' seemed to be hinting at a romance between Steve Rogers and [[Comicbook/{{Agent 13}} Sharon Carter]], with the two even kissing in the sequel, ''Film/CaptainAmericaCivilWar''. This element was dropped in subsequent films, with Sharon not even appearing (or even getting mentioned by name) in ''Film/AvengersInfinityWar'' or ''Film/AvengersEndgame''. While Sharon does reappear in ''Series/TheFalconAndTheWinterSoldier'', the fact that the series instead focuses on [[LegacyCharacter the new Captain America]] and Steve never appears means that the romance plot is never picked up on.

** The New Avengers at the end of ''Film/AvengersAgeOfUltron'' were hyped up as a replacement roster because of Tony retiring, Hulk going missing and Thor leaving to look for the Infinity Stones. They proceeded to do one onscreen mission in Civil War which lead to the eponymous conflict and then quietly disappeared until ''Film/AvengersInfinityWar'' 3 years later.

* In the beginning of ''Film/ZombieLandDoubleTap'', some new zombies are introduced: [[WesternAnimation/TheSimpsons The Homer]] which is so stupid it's zero threat whatsoever to the survivors, [[Film/TheTerminator The T-800]] that is ''very'' [[DamageSponge hard to kill]], and [[UsefulNotes/StephenHawking The Stephen Hawking]] which is a zombie shown to be [[ItCanThink intelligent enough]] to comprehend what a retinal scanner is and use a corpse's eyeball to open it. Ultimately though, this is a concept that basically doesn't go anywhere: The Homer appears only once more as a BrickJoke in the very end, the T-800's reappear throughout but [[DegradedBoss unlike their introduction]] don't pose any more of a threat than normal zombies, and the intelligent Stephen Hawkings are never so much as seen or mentioned again.

* One of the many {{Sequel Hook}}s at the end of ''Film/TheAmazingSpiderMan'' involves Peter attempting to track down the man who shot Uncle Ben. In ''Film/TheAmazingSpiderMan2'', this plot thread is never even mentioned. Likely this was meant to be continued in a future film, however with the series now canned so Spider-Man can join the MCU, it'll never be resolved. The sequel had its own share of unfulfilled sequel teases, most notably a scene set in an armory containing Comicbook/DoctorOctopus’ arms, the Vulture’s wings, the Rhino’s armor, and other supervillain weapons that were clearly meant to foreshadow Spidey having to fight [[LegionOfDoom the Sinister Six]] in a sequel or SpinOff. Felicia Hardy was also introduced in a small role that was meant to set her up to become Comicbook/BlackCat in a future installment.

*** Back when ''Justice League'' was first announced in 2014, it was originally titled ''Justice League: Part I,'' with plans for ''Part II'' to be released in 2019, and a hypothetical third installment following some time after that. As such, ''Zack Snyder's Justice League'' contains a direct lead-in to a sequel, with Comicbook/{{Darkseid}} preparing to attack Earth and Comicbook/MartianManhunter arriving to warn Batman that the conflict isn't over. As of now, Warner Bros. maintains that ''Zack Snyder's Justice League'' is intended to be the end of Snyder's story arc rather than the start of a Justice League trilogy, meaning this won't be followed up on for the foreseeable future.

*** Comicbook/LexLuthor is last seen recruiting Comicbook/{{Deathstroke}} to take down Batman, which was meant to lead directly into Creator/BenAffleck's solo ''Batman'' film, which was planned to feature Deathstroke as the main antagonist. Due to [[CreatorBreakdown Affleck stepping away from the project in 2017]], ''The Batman'' was subsequently reconfigured into a complete ContinuityReboot with no relation to Zack Snyder's planned arc.

* ''Film/AnimalHouse''. In three scenes, we see the Deltas stealing the exam answers (unbeknownst to them, the wrong ones, planted by the Omegas), the Deltas taking the exam as they wink to each other and Marmalard smirks to himself and then Boon saying that he heard from "the Jewish house" that the answers they had were the wrong ones. They seem to be building up to a payoff where the Deltas learn that they did in fact have the wrong answers and that's why their collective GPA has crashed, which would give Wormer what he needs to revoke their charter. While this plausibly happened it only seems to be implied by later scenes in the movie.

* In ''Film/FaceOff'', it's explained that they made Sean Archer sound like Castor Troy (and vice-versa) by implanting a small microchip in his larynx that will cause his voice to sound different. The doctor who performed the surgery takes great pains to explain that the chip is very fragile and easily dislodged, mentioning that even a strong enough cough could cause it to fail. This little tidbit never factors into the plot, not at all.

*** Comicbook/LexLuthor is last seen recruiting Comicbook/{{Deathstroke}} to take down Batman, which was meant to lead directly into Creator/BenAffleck's solo ''Film/TheBatman2021'', which was planned to feature Deathstroke as the main antagonist. Due to [[CreatorBreakdown Affleck stepping away from the project in 2017 amidst his struggles with alcoholism]], ''The Batman'' was subsequently reconfigured into a complete ContinuityReboot with no relation to Zack Snyder's planned arc. Part of this retool meant abandoning Deathstroke as the villain and replacing him with Comicbook/TheRiddler, removing any payoff the tease at the end of ''Justice League'' was meant to have.

* ''Film/{{Underworld}}'': A big part of the fourth movie's story showed that [[BrokenMasquerade humanity found out about the existence of vampires and lycans]] and started a extermination war against them. Come the sequel which is set a few years after the previous one and not even a mention of said war as if it never happened in the first place, with humanity going on their way unaware that the two races are back and resuming their old secret feud like they did in the previous movie.

** Similarly to how ''Film/TheForceAwakens'' focused on Han Solo and ''Film/TheLastJedi'' focused on Luke Skywalker, ''Film/TheRiseOfSkywalker'' was supposed to have General Leia as a major character. Creator/CarrieFisher's [[AuthorExistenceFailure tragic passing in December 2016]] completely destroyed these plans, and Lucasfilm stated they wouldn't digitally recreate her likeness as they had with her and Creator/PeterCushing in ''Film/RogueOne''.

* ''Film/{{UHF}}'': Raul Hernandez, the eccentric animal show host, is dropped from the movie midway through. [[RealLifeWritesThePlot His actor, Trinidad Silva]], [[AuthorExistenceFailure died in a car accident before his scenes were completed]].

This element was dropped in subsequent films, with Sharon not even appearing (or even getting mentioned by name) in ''Film/AvengersInfinityWar'' or ''Film/AvengersEndgame''. Sharon will reappear in ''Series/TheFalconAndTheWinterSoldier'', but as the title makes clear, that show is about [[LegacyCharacter Captain Americas other than Steve]].

** As much of ''Film/ZackSnydersJusticeLeague'' was originally written and shot before the drastic shakeup of the franchise that occurred after the underperformance of ''Batman v Superman'' and the outright failure of the theatrical ''Film/JusticeLeague'' cut, the movie contains a number of {{Sequel Hook}}s for projects that never came to fruition:

*** Ryan Choi also receives a suspiciously prominent scene at the end of the film, which Snyder confirmed was meant to tease a solo ''Comicbook/TheAtom'' Spinoff that was ultimately rejected by the studio.

* In ''Romance on the High Seas'', Oscar Levant's character is continually seen working on a jazz composition called either "Cuban Rhapsody" or "Brazilian Rhapsody." After the characters finally disembark in Brazil, there is a short ballroom dance which looks like a teaser for an epic BusbyBerkeleyNumber (choreographed by Berkeley himself). Instead, Creator/DorisDay's character reprises "It's Magic," thereby wrapping up the movie at a much lower pace and undoubtedly much lower budget.
