Continuity mistake: When James and the kids are going down the dirt road in his car, the road is muddy and wet. When the camera pulls away for a birds-eye-view, the road is suddenly dry.
Continuity mistake: As Barrie (Depp) and Frohman (Hoffman) are sitting in the theatre shortly after Barrie seeing all the sets being removed from the theatre, there are a number of guys removing what look like set doors. The first two guys that walk behind Barrie make a large distance between seeing them and walking down the hall. A few seconds later two more guys just walk past the back of Barrie and in the very next shot they have disappeared.
