Continuity mistake: In the very first scene in the movie, where we see Steve listening to the motivational tape, he is wearing a red tie with polka dots. Then, when he is shown walking toward his boss' office and he falls, you can see that his red tie has changed to a gold tie. When he is in his superior's office you can see that it is back to red, and when he goes to find Stavi in the restroom the tie is gold again. (02:00:00)
