Continuity mistake: The right side of Miller's [Ryan Phillippe] shirt collar is underneath his suit jacket, but in side views, the shirt collar extends above the jacket (i.e, is visible up his neck). (00:08:45 - 00:09:10)
Revealing mistake: When Miller is stopped by police and looks into his side mirror, it looks like the police officer is coming out of the passenger side of his car. The front view shows the officer emerging from the driver's side, like he should be. (00:22:00)
