* CreatorKiller / StillbornFranchise: Almost. This was the first movie since '' SinbadLegendOfTheSevenSeas'' that actually lost the company money. Dreamworks was forced to lay off over 300 employees just to compensate for it. Since then, Dreamworks has come out to the public revealing that they need CashCowFranchise to stay afloat, and given that this movie flopped, chances of a sequel is not likely.
* WhatCouldHaveBeen: LeonardoDiCaprio was originally going to voice Jack Frost, but he dropped out supposedly because of schedule conflicts. His voice is somewhat higher and would've fit Jack's apparent age more than ChrisPine's. (Leonardo had previously played a character named [[{{Titanic}} Jack]] as well.)[[note]][[spoiler: Which would have been one ''hell'' of an ActorAllusion as both versions of Jack involve death by drowning in freezing cold water!]][[/note]]
** Early casting reports also reported ChristopherLee as a choice for the voice of North.
** This is why Bunnymund is such a different character- he ''was'' going to be closer to the books until they brought HughJackman in as his voice; which is where he then immediately became the warrior type he is in the movie.
** Creator/GuillermoDelToro's suggestion for the story was to have Jamie be the AudienceSurrogate. And at least one early version had the climax take a darker turn in which Pitch uses his Nightmare Galleon to harpoon the Moon to create an eclipse to gather his dark forces under for an assault against the Man in the Moon himself.
*** And as shown in the Art Book of Rise of the Guardians there are several illistrations of Sandy's Sandship, which flies around the world constantly remaining within the twilight time zone region to help Sandy spread dreams. The ship took many forms all revolving around an ocean theme with the ship even resembling a turtle and whale at one point. The ship was to be included in battle against Pitch, where the Nightmares overpowering the ship and eventually consuming it, with Jack reaching out for [[GoingDownWithTheShip Sandy's hand before he fades as well]].
** [[http://rufftoon.tumblr.com/post/41565341085/animationtidbits-rise-of-the-guardians-shane#notes Some more early concept art for the film]] reveals that initial designs for Pitch were much more demonic and nightmarish than the film's version of him, which isn't all that different from the books. The concept art also reveals a scene in which Pitch joins with his nightmare sand and becomes as tall as a skyscraper, raining nightmares down upon the world, with Jack clinging on for dear life and looking down at the nightmare sand entering peoples' homes.
** There was almost a Jack Frost doll made by Creator/{{Mattel}}.

* Translation error: In the German synchronisation, Bunny is not afraid of the Groundhog beeing chosen as a new Guardian, but of it beeing the "Butzemann". This is not only odd, but outright wrong, since the Butzemann is a synonym of "Der schwarze Mann", which is the Bugeyman...
