Continuity mistake: Near the end when the Chineese delivery guy pipes up and says he will go into the vault, he has chopsticks full of noodles. After the camera switches back to him, the chopsticks only have a few noodles on them. The camera switches to another person then back to the delivery guy, who is about to eat the noodles, and he has a large portion again.
Revealing mistake: When the blue record gets messed with, they decide to blow the 2nd set of explosives anyways because of impatience. It's obviously heard and the FBI guy wants to check it out. The first explosion made a dusty mess which took a while to clear. How did they clean up the 2nd explosion, and have time to put boxes in front of it before Ben and the FBI guy got down there? There was very little time in between the explosion and them getting to the basement.
