Continuity mistake: While being chased by the 3 BMWs, the passenger's headrest of the Dodge minivan driven by Brad changes from a 1-piece (part of the seat), to a headrest that you can adjust the height and it keeps changing during the scene.
Continuity mistake: When Pitt is chasing after Jolie, he crashes through a fence and fires his gun, hitting the car's windshield. To the left of where Pitt is, you'll notice that there's one rail missing in the middle. When he climbs through the fence to the street, the fence rail has returned, and the hole left by Pitt is now slightly wider, just enough for him to climb through. (00:45:40)
