Continuity mistake: During the film's climax, in which the Wolf's wife Serena is on the run, CIA agent Peter Brandt tries to ambush her in an elevator. As he runs up to the elevator, we get a wide shot of him, the people waiting for the elevator, and the up/down indicator lights of the elevator. The down indicator is lit. (The shot pans down from the indicator lights as he runs up.) Cut to Elias briefly, then back to the elevator indicators. This time, neither light is on.
Continuity mistake: In the scene in the terrorists sympathizers' office, Arnold has a baseball bat and is attacking the man in charge. The FBI break in and shoot Arnold with a Tazer; he drops the bat, but it is right back in his hand in the next shot as if he never dropped it.
Continuity mistake: After Arnie speaks to the motorcyclist cop, you see the governor's cars in the distance pull in and park. In the next shot, the cars pull in and park again.
