History RefittedForSequel / Film

** The original idea of Elsa being the BigBad of the film early in development could be considered as an inversion of the trope, as the idea of the BigBad being [[CainandAbel the biological older sibling of the protagonist]] who opposes said protagonist for most of the movie was already previously visited before in ''WesternAnimation/BrotherBear''.

** The ending of ''Film/CurseOfChucky'' with the court case and Chucky being among the evidence and Fioana being declared legally insane was intended for the beginning of ''Child's Play 2'' with Karen Barclay's character.

* The scene in ''Film/GhostbustersII'' where a woman gets attacked by her fur coat coming to life after she walks through a slime puddle was originally written for the first film. Also, the part where Ray knocks out the whole city's power is a refit from the original screenplay: Egon's prototype Proton Pack, which needed to be plugged into a heavy-duty outlet (for safety reasons, he hadn't fitted the particle accelerator yet). Plug in, switch on, and...the power went back through and melted the cable, reached the outlet, and knocked out all of New York's power.

** The opening to ''Film/TheLostWorldJurassicPark'' where a ''Compsognathus'' swarm [[ZergRush ambushes]] [[WouldHurtAChild a little girl]] is adapted from the opening of the first ''Literature/JurassicPark'' book. The girl is even named Cathy Bowman, which was the exact name that her counterpart in the book had.

* ''Franchise/JurassicPark'':
** The opening to ''Film/TheLostWorldJurassicPark'' where a ''Compsognathus'' swarm [[ZergRush ambushes]] [[WouldHurtAChild a little girl]] is adapted from the opening of the first ''Literature/JurassicPark'' book.
** Other ideas were recycled from the original literary ''Jurassic Park''. Among these was the scene where a swarm of a small dinosaur, ''Procompsognathus'' in the book and ''Compsognathus'' in the film, killed a villain after they fell down a hill (John Hammond in the book and Dieter Stark in the film). Also from that book was the ''Tyrannosaurus'' waterfall encounter, where it would peek through the water and extend its tongue to lick at the humans trapped there and attempt to grab one, in the book, Lex and Tim were there and the ''Tyrannosaurus'' would've eaten Tim if it wasn't for a tranquilizer dart fired by Robert Muldoon knocking it out, but in the film, it corners Sarah, Kelly, Nick, and Robert Burke, and actually succeeds in taking Burke (though it does briefly lick Sarah in the same way the tongue was used on Tim in the book before Burke runs in front of the dinosaur). A third scene from the literary ''Jurassic Park'' was the ''Velociraptor'' pack sneaking into a ship bound for the continent (though scenes with ''Velociraptor'' aboard or on the mainland were cut, leaving the crew's deaths in the film [[AdaptationExplanationExtrication unexplained]]). Also the baby ''Tyrannosaurus'' killing Peter Ludlow may be a reference to how a mature juvenile ''Tyrannosaurus'' ate Ed Regis (a book character [[CompositeCharacter composited]] into Donald Gennaro to give him his DirtyCoward behavior) in the book. A baby ''Triceratops'' that was built for a DeletedScene in the first film also gets to appear in this sequel.

** A proposed plot was Vulture's motivation involving arms dealing and grand theft to provide care for his ailing wife and troubled stepdaughter, Felicia Hardy. This was partially fulfilled in ''Homecoming'', except Toomes' wife is quite healthy, and his daughter is [[Characters/SpiderManSupportingCharacters Liz Allan]].

* ''Film/{{Superman}}''

** In the [[Film/BackToTheFuture first film]], the producers considered using "Papa Loves Mambo" by Perry Como when Marty arrives in the 1955 Hill Valley, before deciding on "Mister Sandman" by The Four Aces, thereby making it the MisterSandmanSequence. In ''[[Film/BackToTheFuturePartII Part II]]'', the song is used as Biff drives to the Enchantment Under The Sea dance.

* ''WesternAnimation/WreckItRalph'' originally had another game named Extreme E-Z Livin' 2 (a mix between Grand Theft Auto and The Sims . The game was renamed to Slaughter Race for the ''[[WesternAnimation/RalphBreaksTheInternet second film]]''

* An interesting variant for ''WesternAnimation/SpiderManIntoTheSpiderVerse''. Peter B. Parker's story arc in this film reuses ideas from the unmade ''[[Film/SpiderManTrilogy Spider-Man 4]]'', specifically him divorcing Mary Jane. The original script for that movie had it come as a result of him cheating on her and ended with him [[TookALevelInJerkass abandoning her and their child]]; Creator/SamRaimi felt that this made Peter come across as an [[DesignatedHero unlikable jerk]], contributing to the problems that ultimately got that film scrapped. ''Spider-Verse'' has the reason for the divorce be Peter simply undergoing a mid-life crisis that went FromBadToWorse after Aunt May died, causing him to act in an impulsive and self-destructive manner that ruined his marriage. [[spoiler:It also ends on a much happier note, with him regaining his resolve and trying to patch things up with MJ.]]

* Finn [=McMissile=] was originally going to appear in the first ''WesternAnimation/{{Cars}}'' film as a character in a movie Lightning [=McQueen=] and Sally Carrera were watching in at a drive-in movie theater, but that scene was cut. He would be used as one of the central characters in [[WesternAnimation/{{Cars 2}} the first sequel]] instead.

** Concept art for "Warthog Rhapsody", which was replaced by "Hakuna Matata", uses a waterfall scene that looks like one used in ''1 1/2''. The tune for the song was reused for "That's All I Need".
