Continuity mistake: When Pierce first begins to interrogate Caliban in the safe house in Mexico, a large portion of Caliban's albino makeup is smudged below his nose, revealing the actor's natural skin in his first close-up of the scene; after switching to a close-up of Pierce, then back to Caliban, the smudge has been fixed.
Continuity mistake: When Pierce is in the limousine, he pulls out a business card, and holds it out to Logan, who doesn't take it. In one shot, Pierce holds it with the writing facing himself, but in the next shot, it's upside down with the writing facing Logan, and you look closely, it only has print on one side.
Continuity mistake: Before crashing the limo into the fence, there are two bullet holes in the rear windscreen. Afterwards, there are five. Then from an inside shot as they start backing up, there are only two again.
