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.
Pennywise the Dancing Clown - Bill Skarsgård
Bill Skarsgård portrays the newest version of Pennywise the Dancing Clown in the 21st Century remake of Stephen King's It. The Swedish actor did everything he could to make this character as terrifying as he was on screen. Pennywise is easily the creepiest character out there already (clowns, right?) but somehow, Skarsgård made him bone-chillingly terrifying. It was probably that perfect smile...
Skarsgård actually comes from a family of actors, His older brother, Alexander Skarsgård, was in the series Big Little Lies opposite Nicole Kidman and True Blood. He was also in The Stand, which is another Steven King classic. Their father, Stellan Skarsgård, appeared in the ever-popular film Good Will Hunting. Bill definitely takes the cake for creepiest character ever played, though.
