Plot hole: In the Redstar mainframe, we are told that the floor of the vault will trigger the alarm if it receives more than 0.25 seconds of contact (apparently even with the security checks). What would be the point of the bosses going through all of those security measures if they would just set the alarm off anyway? Surely once the girls have faked the fingerprint and retina scans, they don't then need to flip across the floor!
Plot hole: In the scene where Cameron Diaz is gaining entry to the Redstar mainframe, she wears a white suit to remain "undetected" in the antechamber. And then, she opens the door into a dark room, meaning that the security camera will spot the door opening if not the person opening it. Whats the point of wearing a white suit to hide from a camera, if the door opening will show up anyway?
