At the very end of the movie when they show Frank (Denzel Washington) getting released from prison, you see a woman approaching him from his right and a man approaching him from his left. Just as they are about to cross each other in front of him, the camera switches to a close-up of Franks face. The camera then goes back to wide view and you see the same two people approaching him again a few seconds later... And this time the timing was off as they would not cross right in front of him but rather a few feet to his left.
