Revealing mistake: On the last building on the getaway run, the door is already open - if it had been closed it would have been too hard for the dogs to open.
Revealing mistake: At one point John is complaining about the Beach Boys playing on his car radio, he reaches to the center console and motions turning the radio off. In a few other shots though, we see that the car appears to have no radio at all, the center console seems to have a large tachometer and speedometer there, but that's all.
Revealing mistake: The square base securing the knife in Alba's back is visible.

Revealing mistake: Flashback to the truck on fire past the Franco-Italian border; the driver chops the lock open, with all the slaves inside banging desperately at the cargo doors to get out of the inferno. Or not; when there's a cut between shots, you can see the lock already came off, but the extras who are supposedly trying with all their might to escape death do in fact wait for the driver to open the door before they start coming out.

Revealing mistake: At the beginning of the movie, the coked-up sailor is shooting from a rooftop and screaming various racial slurs. Despite that, there's a big crowd building. When he shouts "Come and get me, honkies!" you can see people running way before he pulls out of the gun again and shoots. Not only that; some of the extras are just enjoying themselves and not keeping a straight face, far from being scared. (00:01:00)
Revealing mistake: During the credits, Diane Ladd is listed as Diane Lad.
