Continuity mistake: When Joey and Angie enter the rooftop of the building across from the hotel, he stops a vent fan, and bends a blade back so they can get through it. The blade is positioned at about 30° from horizontal, pointing up. Yet in consecutive shots, watching them go through it, it changes position to pointing about 20° down, then back again.
Continuity mistake: Early in the movie Nick is being interviewed by a woman and there is a cup in front of her to the left when the camera faces her.

Continuity mistake: When Joey is on one knee removing the panel outside the vault room his underwear can be seen showing above his jeans, and it appears to be black.

Character mistake: In the scene where the news helicopter comes in close to the building and causes high winds that almost blow 'Joe Walker' off the ledge, Detective Lydia Mercer calls him "Nick". She doesn't know his real name at this point.
