Other mistake: There have been many strange castings in movie history, but letting a character of African American descent, who is supposed to be light-skinned enough to pass as white, be played by blue-eyed Sir Anthony Hopkins, whose African roots, according to widely accepted ethnological theories, date some 40,000 years back, takes the cake. His young ego, played by Wentworth Miller, looks a lot more believable, but, luckily for him, the odds are close to zero that he will resemble Anthony Hopkins even faintly in 50 years from now.
Continuity mistake: When Coleman and Faunia meet for the first time she's working at a shop and about to close. He gets something from a telling machine and drives off home. In the next shot we see him somewhere in the woods driving past Faunia who is standing next to her stalled car, smoking, and giving the impression that she has been already waiting for a while. The question is, however, how she got ahead of him.
