Richard Burgi wasn't cast as Sheriff Bracke until 12 hours before they needed to begin filming his character's scenes.
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!").
Including the 2009 remake, Jason has killed around 200 people throughout the "Friday the 13th" series.
