Continuity mistake: During the sex scene between Milo Ventimiglia and Lauren Lee Smith, in which the fat guy was found dead, three consecutive shots showed that Milo Ventimiglia has his shirt on on the first, then the shirt disappeared on the next, only to reappear on Milo Ventimiglia's body again in the third shot.
Continuity mistake: The car they pour petrol/gasoline over in the closeup shot is a 2007 Chrysler 300C Hemi with the big square-shaped grille. In the long shot where the car blows up, it is not the same car; the grille has changed shape and is more akin to an old Mercedes.
Suggested correction: The grille hasn't changed shape, it looks different because of the explosion damage.

Continuity mistake: When the sergeant balls up the paper with the drawing of Dave and throws it at the cop, the cop keeps it and unballs it. The paper is clearly very wrinkled, but when he puts it in the fax, it is too straight for him to have straightened it out that fast.
Continuity mistake: Near the beginning of the movie when Alexis is getting ready for her first date with Tank, her roommate is holding a cheetah print shirt. The shot changes and suddenly Alexis is wearing it, even though she has not had time to put it on. She is also holding a drink in her hand, but she never puts it down. (Although this is explained on the DVD's Deleted Scenes, it is still a mistake.)
Continuity mistake: When the "substitute" boy gets off the train he is with an older women. The reporters ask the mom and boy to take a picture together. You can see from the camera angle that the older woman is in the background when the flashes go off taking the picture. Later in the movie, the psychiatrist holds up a newspaper article with the picture in it. In the newspaper picture, the older woman is not in the background.
Continuity mistake: At the end, Casey and Elaine flee the house in the Volvo and find Chloe's crashed SUV. As Casey goes to investigate the SUV on foot, Miranda suddenly comes sprinting out of the woods, intending to kill Casey. To save Casey, Elaine rams Miranda with the Volvo, slamming her into the rear of the SUV. A camera shot from inside the SUV looking out shows that Miranda impacted right in the center of the SUV's rear hatch. In the same shot, we see Miranda's lifeless body slowly slide straight down the hatch, meaning her body should have collapsed directly between the Volvo and the SUV. When the camera cuts to an exterior view, we see Miranda's lifeless body stretched out in the snow (parallel to both vehicles) a couple of feet away from the Volvo's front right fender; so her body is now about 6 feet away from where it should be.
