There's a tradition of reenactment in documentary which is about sort of illustrating what the past might have been like.

The killers have built the society. The whole Indonesia is their platform. They run the country. They run the country.

I think we create our world through stories. We use storytelling to escape or protect ourselves from the unimaginable and the horrible - from the real, in a way. It's like white light - if you put everyday reality through a prism you get this rainbow of colors that you couldn't see before. I'm interested in exploring the world to show the things that are invisible. And not just undocumented aspects of reality, but to actually make manifest things that have been hitherto invisible through the intervention of filmmaking.

I believe every time you film anybody, you create reality with that person - whether it's fiction or nonfiction. If you acknowledge that filming is an occasion where people express things they might not otherwise express, that offers a much more insightful analysis of why documentaries - even of the fly-on-the-wall variety - are powerful. I think that our task as filmmakers is to create the most insightful reality given the most pressing questions.

People create the illusion of acting natural, which is what I think most documentarians do in part because of the direct cinema orthodoxies that came into play really in the '60s. That moment of performance is a tremendous opportunity to make visible something hitherto invisible, which is how people want to be seen. How do they see themselves? What are the scripts, fantasies, genres by which they imagine themselves? How is storytelling part of what we are as human beings? We wouldn't kill each other en masse if it weren't for storytelling. We wouldn't be able to live with ourselves.

Direct cinema is about simulating a reality in which you're not having the overwhelming influence that you really are having.

I need to trust myself and go where my instincts tell me, and to be as wild and free as possible in my creative decisions.
