Skateboarding was everything to us growing up. It changes the way you see the world: you spend all day looking for ditches.

Here's the thing that people don't understand: I don't really care. I've never been a careerist. It's not a strategy. I react to certain characters and story lines and specific mode of filmmaking.

When I was a kid, I loved Nicholas brothers films. It was like skateboarding. Even Gene Kelly: I always preferred him to Fred Astaire, just because he was more athletic, like skateboarding.

I tried working odd jobs that had nothing to do with creating, and it was difficult for me. In the end, I just always loved movies. When I'm making a film, I feel most alive, like I'm doing the right thing, and I'm in the place where I need to be.

I have a crazy imagination, and it's a visual one that can be scary from time to time.

No one forces me, or any other writer, to sell a film option on the books. If you don't want to run the risk that the filmmakers may adapt your work in a way you don't like, then you don't sell the option. You know when you sell it that they will have to make some changes, just because film and TV are different media than books.

I don't know if I can see myself writing another 'Saw' film. It's such a special part of my life, and I almost don't want to ruin it by going back.

I never really knew I wanted to 'be' a writer, but I was always writing from a very young age. It became more conscious as an ideal when I was in my twenties.
