Continuity: How come when they go through the lasers it takes 2 minutes to get to the mask, but it only takes 30 seconds to get back?

Plot hole: When Gin (Zeta Jones) is stealing the mask, she uses the switch and then sticks a chewed piece of gum on the stand. If she leaves the gum stuck there, security could easily do a DNA test on it. If she replaces it with that monkey mask, where was that the entire time? She couldn't have hidden that in her jacket without it being seen.

Continuity: When they are staying in Malaysia, Zeta Jones is mentioning that they have to do the "electronic robbery" the following night. 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.
