Entrapment Catherine Zeta Jones isn't supposed to touch some strings that she is working her way through, but you see a bell hanging on the string move - it's agreed by the characters that she does do a perfect job, when actually she would have set the whole alarm system off.
Fine powder is sprayed on a security door keypad to determine which keys are used to get in.
If you take a tenth of a second a minute for 60 minutes, you end up with only 6 seconds. 4 seconds short of the required 10. As a matter of fact it has to be the night after that one, because there are two bits of darkness - one where Sean Connery plans the job and one where they fight and make up. When Catherine Zeta-Jones practices with the bells and strings maze, she is careful to lift her left leg over one of the first strings, then brings her body through, and then brings her right leg over the string. Too bad when she does the heist of the mask for real, she lifts her left leg over the unseen laser beam but keeps her arms dangling as she brings her right leg over.
