Audio problem: When the alley cats are chasing Stuart and he's trying to start his car, he says "Come on" but his lips don't move at all. On top of that, wherever we see the cats running or from a distance, their mouths don't move at all when they talk.
Stuart Little (1999)
1 audio problem - chronological order
Directed by: Rob Minkoff
Starring: Michael J. Fox, Hugh Laurie, Geena Davis, Nathan Lane, Jonathan Lipnicki
Continuity mistake: In the first shot before the boat race begins, Geena Davis is wearing a hat. Throughout the rest of the boat race scene, she isn't wearing the hat.
George Little: Maybe we should go home.
Mr. Little: Why?
George Little: I'm not wearing my lucky underwear.
Mr. Little: You don't have lucky underwear.
George Little: Well, maybe we should get some, and then come back for another race.
Chosen answer: It's a fantasy world, like Harry Potter and the Narnia movies.
