Revealing mistake: When Kyle, Elizabeth and Robin are in the truck being chased by Mr. Chiang, in all the outside shots of the truck it is very easy to see that all three of them have been replaced by doubles.
Revealing mistake: Extremely obvious stunt double for Kyle Bates when he escapes from the clutches of Mr Chiang and jumps off the roof. The stunt double looks absolutely nothing like the actor, and his face is very visible.
Continuity mistake: When Ham and Mike come out of the main door of the building, Mike shoots a guard standing on the roof. The guard falls off, but when the shot switches back to Mike the guard isn't seen falling to the ground.
Revealing mistake: When Diana offers the ants to the two officers, she is gripping the handle differently between the far shots and the closeup. Needless to say in the far shots the officers are not eating real ants.
