Character mistake: When Charlie is calling out the brick count to Napster from the subway, he describes it as being "13 across, 4 high, 4 deep". The bricks appear to be 2 deep in the safe (13x4x2), so he could just be lumping two shelves together, which works (13x4x4 = 13x4x2x2). The problem is that when the camera pans down there are 3 shelves in the safe. This means that there are more than the 208 bricks that Napster announces.
Question: When Charlie and Steve have their discussion about the gold and Charlie punches Steve in the face, Charlie takes several bills out of his pocket, puts them on the table, then leaves. What does he put money on the table for? It's not like he broke anything with his punch, and surely not to pay for Stella's meal, and especially not for Steve's meal either.
Question: During the Venice boat chase at the beginning of the film, a large number of vessels are flying a flag which looks more like the flag of Mexico than that of Italy. Or are they perhaps flying the 'Kingdom of Italy' flag which looks similar from a distance to the Mexican National Flag? Can anyone help?
