Richard Burgi wasn't cast as Sheriff Bracke until 12 hours before they needed to begin filming his character's scenes.
Including the 2009 remake, Jason has killed around 200 people throughout the "Friday the 13th" series.
Victor Miller, the screenwriter of the original Friday the 13th (1980), said the script was written in such a way that it could be deemed a sequel as opposed to a remake, because that meant they could pay him less if the movie qualified as a "sequel." This explains why the plot of the film is more of an amalgamation of the first four films, as opposed to a re-telling of the original film. Miller took legal action, because he felt the script they showed him was more of a remake, but the story he came up with was condensed to the first few minutes of the film, he lost the battle, and was paid less. He was surprised later to see the film advertised as a remake.
Adrienne King, star of the original 1980 film, was approached by producers Andrew Form and Brad Fuller to do a cameo appearance during preproduction. A few days later, the producers called her back and told her they didn't want anyone from the original film to appear in the remake.
A wheelchair and a sweater can be seen in Jason's tunnels during the film. The character Mark (Tom McBride) was a paraplegic who was killed by Jason in Friday the 13th, Part 2 (1981) and Mrs. Voorhees wore the sweater in the original version of Friday the 13th (1980). There's also a bicycle propped against the wall, just under the wheelchair. It's likely Ralph's bicycle, also from the original Friday the 13th ("It's got a death curse!").
