Unlike most live-action films, which have a (at least mostly) completed script before cameras ever begin to roll, animated films are usually much more in flux. The “story” part of an animated film is never really done, which has resulted in many animated movies going through big changes from their inception to their completion. It’s not unusual for entire characters to be added or removed from stories, or to see plots go through major overhauls. But few films have gone through quite as many changes as The Emperor’s New Groove, which was so different at the beginning that it's fair to call it an entirely different movie.
Titles change so often in all kinds of movies. Disney’s Frozen was originally going to be called Anna and the Snow Queen, but despite the fact that Elsa went from being a villain to a misunderstood hero of the movie, the core elements of that movie never really changed. However, The Emperor’s New Groove is a movie that was built from the ashes of a very different film called Kingdom of the Sun.
