Continuity mistake: When Mathew Perry goes to Chicago to meet with the head Boss, Bruce Willis' wife comes to talk with him at the hotel. In the scene where he is brushing his teeth he picks up the mouthwash bottle and swigs some, then sets the bottle down on the counter. The camera cuts back to her, then back to Matthew Perry, and the mouthwash is gone. (00:32:50)
