I'm interested in art, and I think about the process of making art. It's part of my personality, my experience of the world, so it ends up in the movies. It's where my head is.

I think generally I'm kind of interested in subjective experience, what goes on inside someone's head, that being all they really know of the world.

Scary is time passing and sickness and dying and regret and isolation and loneliness and relationship problems - as opposed to a guy in a hockey mask, which didn't seem that scary.

And also the idea of not making it apparent that it's different from the rest of the film, even though there are visual differences, the audience is supposed to think that they are with him when he wakes up in the morning.

Seriously, I don't consider myself a writer. I don't think I have writing talent. But I will continue to do it.

As a kid, I had a background in theater.

You get a kind of surreal feeling and also it allows you to focus on the things we want you to focus on in a new way - the stuff that's very small and mundane that happens in a person's life when they're in a hotel room. There's more interest because you're seeing a puppet do things that you're very familiar with that you might not notice if it was a human doing it.
