Revealing mistake: In the scene where Jane is trying to run over John with her car, she jumps from the driver's seat while John is in the back of the car. Right before the car crashes through the fence, you see John through the back window. You also see a head in the driver's seat, even though no one is supposed to be driving the car.
Revealing mistake: When Pitt is on the roof of Jolie's car, he breaks the window in order to get into the car. First off, when played in slow motion, the feet never do touch the glass before it explodes. Second, all newer vehicles have shatter proof glass both on the windshield and the side windows. In real life the glass would have just cracked, not blown out as it did in the film. (00:46:25)BillyBlake
Revealing mistake: While Jane drives the minivan, after John tells her that he knew he saw her "father" on Fantasy Island, there's a closeup of the rearview mirror's reflection just as Jane sees the two BMWs still chasing them, but the view we see within the mirror's reflection is not backwards.Super Grover
