I believe there's a landscape that exists underneath everything that we can see in present-day stuff. And I think that makes life kind of a detective story.

We shoot double episodes in 15 days in Los Angeles.

Dark impulses certainly exist in me and, I think, in most people.

I directed 24's pilot. I felt we should follow the characters around as if we were a documentary crew, using available light, hand-held cameras, split screens, sound that isn't always what it should be, to suit the reality of the premise.

I have an adult emotional life and an editing system inside me which prevents me from being preposterously stupid.

Each environment has its own signature. Sound tells a story: You make choices about what you're hearing, where to look, how you want to feel about what's going on.

To be able to rely completely on the actors was a very simple process for me.
