Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Other mistake: In the scene where Andrea is being sucked into the fan at the Gotham worlds fair, Batman rides in on his motorcycle. He turns into the fan to rescue her, but his cape is flapping in the opposite direction in which the fans are sucking.
Other mistake: During the train chase Wallace steps onto the train track that's going to the left on-screen, then he goes to the right as if the train is going the opposite direction on the track.
