Revealing mistake: During the bank hold-up at the beginning of the film, one of the pushes a man on the wall. It wobbles like cardboard.
Other mistake: The bank robbers only took old notes, but the lead detective on the case reads out how much money was stolen: "Two million, six hundred and sixty-seven thousand, five hundred and twenty-seven dollars and sixty-two cents." There wasn't any change, it was all notes.
Continuity mistake: About 15 minutes in, Yaphet Koto and another man are in an elevator; there are hostages on the floor. Yaphet pulls a glove onto his left hand, but, in the next shot of him, he again pulls a glove onto his left hand, and then yet again he pulls a glove onto his left hand. The same hand three times.
Continuity mistake: After the bank robbery, in the cemetery, the hatch window of the Ford is closed and the shot after, it is opened.
