When you make a documentary film, after many years the only thing you remember is what you put into the film, not what you took out.

The digital revolution has had a democratizing effect. Now anyone can be a filmmaker, but to be a good filmmaker is as hard as it ever was.

I'm an eclectic and avid filmgoer. I try to see everything from romantic comedies to blockbusters to art house films, world cinema and documentaries.

The biggest misconception about me and my work is that I only make political films denouncing human-rights atrocities, even though all of my films are about people fighting for their rights and their quest for justice. My films aren't depressing, are very human, and always offer a way forward.

I truly value the cinema experience, the tribal gathering in the dark to watch something larger than life. I like to sit in the first row with no heads in front of mine, and become one with the screen. I always stay for the complete credits so I can linger in the film's story just a little longer.

My advice to emerging documentary filmmakers would be: try to find other people, a group, a cooperative that you can work with. Filmmaking is hard and lonely and decidedly unglamorous. Find like-minded souls and share the joy and the misery.

Witnessing is the essence of being a documentary filmmaker. Capturing moments in time; never knowing how history will judge them.
