At first, Kirzinger was Jason's stunt double in the 1989 film Jason Takes Manhattan. He returned for Freddy vs. Jason and played the killer during the entire film. There was something about Kirzinger's body language that made him so scary... Much scarier than the previous Jason's. His acting made the film pretty enjoyable compared to the other ones.
Leatherface - Andrew Bryniarski
Leatherface was slotted to be played by someone else, but the first actor had to drop. The studio decided to call Andrew Bryniarski to fill the role, which worked out incredibly well. He truly embodies the scary villain!
