We lie to ourselves and try to escape that bitter reality by saying that the world is divided into good guys and bad guys, and that we're the good guys. We condemn people as evil to reassure us that we're not like them. If there's to be any hope of preventing these things from happening again, we have to look at the reality. That any act of evil in our history was committed by human beings like us. That, very often, we're all implicated in it.

I'm trying to understand how do we tell lies to ourselves to justify what we've done and what are the consequences of those lies? But actually maybe I also recognize that in turning empathy into a practice for many years, by turning, by forcing myself to separate at some level the humanity of a human being from his or her actions and recognizing that sometimes, even the moral aspects of a human being can contribute to immoral behavior.

Films can't change the society, they can simply open the space for the discussion which can lead to social change and can start new forms of social activism. I feel formally that I've scratched the surface of something very important about the nature of nonfiction film, about what we're very rarely honest about: When you film anybody, they start performing.

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.

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.

In Indonesian, the word isn't translating as "gangster." It's "preman", which comes from the Dutch "préman", which of course the thing that's "freeman" in English.

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.
