Factual error: At the beginning of the movie when Anthony Hopkins' character points out to the academic board the definition of "spooks" in the dictionary, it seems to be too close to the front of the dictionary to be in the S section.

Other: 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: When Anthony Hopkins first gives Nicole Kidman a ride to her place, it is raining outside. When he gets out of the car to go inside, the entire windshield is dry and clean as a whistle, even the area that is outside the reach of the wiperblades.

Other: At the end, when Nathan Zukerman talks to Faunia's ex on the frozen lake, there are no breathing clouds, while the sound of Nathan's boots in the snow suggests that it is bitterly cold.

Continuity: In the flashback when the young Coleman Silk is having lunch with his mother and Steena Paulsson, the beans on his mother's fork disappear between shots and the fork itself changes position.

Continuity: 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.
