Continuity mistake: In the scene, towards the end of the movie, Billy Baldwin is running down the street chasing the cab that the girl he wants is in. His shirt changes from having a pocket to not having a pocket. The colour also changes from yellowish to more brownish.
Other mistake: After Molly crashes the taxi, she is standing outside in the bitter cold. Yet you never see her breath (vapor) when she is speaking or when she is huffing and puffing when confronted by the wolf.
Continuity mistake: This movie has many flashbacks to the late 1970s or early '80s, but in one scene the little boy is in his pajamas and it depicts symbols of NHL teams. Half, if not most of those teams were not around at that time.
Continuity mistake: In the hotel scene where Darby calls Gavin to give him the instructions to meet her the next day, he eats one of the chocolates on his pillow and throws it down. They show a close up of the chocolates. After Khamel murders Gavin, he walks to the bed, pulls the recording device and eats one of the chocolates. They are now in a different spot on the bed. (00:59:55 - 01:00:25)
Continuity mistake: The last shot, when the camera pans away from the front door of the house, appears to be taken from a helicopter, and a modern 1990's white car can be seen parked behind the property in a courtyard. The shot was meant to be at the end of the 1950s. There's also a motorway in the background with lots of fast moving traffic.
Continuity mistake: When Jack shows Joseph the first hornworm the way he is holding the tobacco leaf changes when the camera goes from close-up to a wider shot. (00:51:25)
Audio problem: After Batman has left Andrea's apartment she drops a glass. We hear the sound of the glass shattering, but when the camera zooms out we see the glass is still in one piece.
Visible crew/equipment: You can see a rope visible when Charlie is hanging from the hotel roof.
Other mistake: In the second wedding scene, as Don Pedro and Claudio are walking up the aisle you can see an extra jumping over the benches on the left-hand side of the screen. He clears the first one, but trips on the second and falls flat on his face.
Continuity mistake: During the final fight between Jean-Claude and the bad guy, they are both holding onto a shotgun. Initially the barrel of the gun is in J-C's left hand. But without either of them letting go of the gun, suddenly the gun switches end-for-end and the stock of the gun is in J-C's left hand. It looks like they probably re-filmed the last of the fight so the bad guy could use his right hand to hit J-C with the butt-end of the gun.
Continuity mistake: As the young Navigator is going to catch the train, the Union Jack flag at the end of the platform is upside down.
Visible crew/equipment: When Doug is pitching his idea to Christian, they are outside on the terrace of the hotel. As Christian is walking inside, he walks past some windows and you can see the camera and the crew in the reflection.
Continuity mistake: After Miranda sings for the hotel manager, her guitar case closes and zips itself in a split-second.
Continuity mistake: In the scene where Ellen and Newland are seated in her living room by the fire, we see her take a cigarette holder charm off of her bracelet. Then, the next scene shows a closeup of the cigarette holder charm, and she is again removing it.
