Other mistake: When Moss confronts the party crasher who has a gun to the arms dealer's head. The party crasher then pours gasoline all over the pumps and Moss shouts "Don't shoot, you'll blow this place up, I'm standing in the shit". As the scene eventually cuts back to Moss on a long shot, you can see that the floor is dry and he's not actually stood in the gasoline. (01:20:00 - 01:21:00)
Other mistake: When Leonardo lifts up the bar he has just fashioned, you can hear a couple of people in the background say "Gold" where the others are and correctly saying "Oro" (Since the Italian word for gold is Oro).
Other mistake: There are several moments while using the clown dummy toy that make it very obvious it is an actor in a suit. Most obvious of which is that it somehow 'senses' things like the momentum and orientation of the person controlling it, when all it is shown to do is copy muscle movements/motor skills. There are far too many examples to list.
