I'm a natural born skeptic.
I think it was in sixth grade, though, when I picked up my first Stephen King book, which was 'It,' that knocked me over and terrified me for years. Then I never went back. I had to own every Stephen King book and read them at least three times. They would terrify me completely, but I couldn't stop. That became my preferred source of fiction.
What you don't want is for violence and gore to become more important than character and structure. A lot of slasher movies from the eighties were only focused on violence and gore, which robs the human beings in the story of any empathetic reaction from the audience, and instead makes them cheer for the gore.
Horror is fascinating because it's so seasonal and it's like you've got these periods where slasher movies are in and it's like everyone loves them. Next thing you know zombies are in. Then vampires are acceptable.
Well when I hear 'slasher' I think about the 80s.
We always try to leave room for the actors to come in and make discoveries on set, in their interpretation of the scene. The shot list is scaffolding.
