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. (01:33:40)
Character mistake: The word "Storyboard" in "Storyboard Artists" during the end titles is misspelled "Stroryboard". (02:05:00)
Character mistake: Before the Megarace, Rez looks back at the camera and says that they'll try to help him out-but you can see Juni's tires in front of Rez's car. In a shot before this one, Rez says Arnold will crush Juni-looking at the camera, which is in front of Rez.
Character mistake: When Selby goes out to meet friends, they talk about going to "Fun World" in Orlando. However, they did not actually visit "Fun World" they went to "Fun Spot" (look at the signs on the ferris wheel and behind the carousel). Fun Spot is located on international drive in Orlando where as "Fun World" is another amusement park. (01:07:55)
Character mistake: When Brian, Roman and the thugs are racing to get Verone's package, Verone does a little research on them. When he looks at Roman's folder there are a couple of shots where they show information about him. If you look closely, you can see that in the last shot they refer to him as Brian and later on as "she". They also talk about his relationship problems in the next paragraph of the same shot. (00:31:50)
Character mistake: In the scene where the photos of Daphne are flashing by, you see her in a photograph which was supposedly taken at the Chelsea Charity Auction. In the caption, "auction" is incorrectly spelled "aution."
Character mistake: When Jamie is first speaking to Aurelia, he says "molto bueno", which the housekeeper woman tells him is Spanish. 'Molto' is actually Italian. (00:38:30)
Character mistake: In the scene where the dentist is doing a root canal, Bloat says "rubber dam and clamp installed?" and another fish replies "yes", but when the picture goes back to the dentist and patient you can plainly see that there is not a rubber dam on the patient. A rubber dam is a large piece of latex attached to a metal frame, to keep water from the dental handpiece from going into the patient's mouth. Although all of the dental jargon in the film is precisely accurate, this device would have been very noticeable.
Character mistake: After the things let the dog out, Larry calls Joan and tells her that the kids let him out, and he will get him (the dog). Later, when he's downtown with the dog, he has the line about "when Joan finds out you've escaped, Conrad's out and I'm in". Where is the surprise? He already called her, so she knows!
