My stuff always starts with interviews. I start interviewing people, and then slowly but surely, a movie insinuates itself.

A lot of the themes of my movies, the actual stories, come from tabloid stories.

Robert Nozick [a Havard philosopher, famous for his book "Anarchy, State and Utopia"] defined revenge as delivering the message that you know what someone has done, and it doesn't involve hurting them or doing anything to them beyond that. It's just delivering the message that their crime has been noted not just by its victims, because the victim might be dead, but by another who has a different moral view and will challenge the perpetrator's view.

I'm asked unendingly to become involved in series involving true crime and as it so happens the Netflix series that I'm working on is about a true crime.

Like all great documentaries, The Act of Killing demands another way of looking at reality. It starts as a dreamscape, an attempt to allow the perpetrators to reenact what they did, and then something truly amazing happens. The dream dissolves into nightmare and then into bitter reality. An amazing and impressive film.

Part of the mystery of any given photograph is the fact that it was taken at a certain time and in a certain place and time keeps moving on. A photograph might be a moment in time preserved, but the world continues to change around it.

I used to work as a private detective years and years ago. And my boss gave me this one very simple piece of advice about trying to figure out who to interview first in any investigation. His recommendation: Always pick the people who were fired. Pick the people who are pissed off.
