Trivia: The filmmakers originally had an ending in which Alex grabs the cable that lies on Clear's car, Alex catches fire and dies. Then Clear gets her baby and Carter survives. The test audience didn't like this, so the filmmakers shot another ending in which Alex is decapitated by a crashing police helicopter. But again, the test audience didn't like the fact that Alex dies, so they shot the finish with the billboard, which took 6 days to film and cost nearly $2,000,000.
Trivia: Right at the end, in fact the very last frame, you can see a face in the snow as the shot fades out.

Trivia: A scene in which Sebastian brutally and graphically rapes his neighbor was filmed, but was mostly deleted as test-audiences felt it made Sebastian far too evil. And thus, the version of the scene in the theatrical cut only alludes to the idea without directly showing it. The original scene was reinstated in the director's cut released on DVD and Blu-Ray however.
Trivia: In the DVD's deleted scene sections, we see what happens to Pamela Fitzgerald in the Halloween party - she is confronted by two policemen and she shows them what she has in the clear plastic tupperware, which contains the fingers of Trina. The police arrest her on the spot and take her away, leaving Sam and Brigitte to save Ginger.

Trivia: Rustin Parr shows up in the movie. In the general store there is a man on the floor "fixing" the fridge. He doesn't move in his scenes and seems dead. The only time he speaks is in Chapter 15 after Kim says "Excuse me" and he says "I'm finished now" Rustin Parr was said to have walked into a general store after killing the Burkittsville 7 and saying the same thing. Also "The Secret Confession of Rustin Parr" by DA Sterns shows a picture of Rustin Parr played by the same actor in the movie.
