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.
Trivia: This movie is the first feature film directed by famed documentary director Joe Berlinger. His original director's cut of the film was much more ambiguous and less reliant on traditional Hollywood-style horror sequences. However, the studio forced him to reshoot several key sequences, add in new scenes and drastically re-edit the film to make it more marketable to mainstream audiences. Berlinger dislikes the version of the film released in theaters, and didn't direct another feature - film until Netflix's "Extremely Wicked, Shocking Evil and Vile," which was released almost 20 years later in 2019. (Though he continued to work as a documentary director in the meantime).
