The Metallica film was like this incredible life experience where I learned the most through guys that stereotypically you would think couldn't offer much to you. That's what I love about the film: It explodes your stereotype of them - they're not just a bunch of lugheads banging on the guitar.

The world is watching, and you better be fair.

My attitude is, I am not a lawyer; I am not a doctor; I am not a scientist. I am a filmmaker and I want to present what each side is saying and let the viewer come to their own conclusion.

I never believe I'm presenting objective reality; I also don't want to delude people into thinking that my subject is talking directly to them.

I'm an observer in life, not a participant. That's why I'm a documentarian who looks through a camera. I'm not a touchy-feely person; I'm not a seminar person.

I actually have come to believe that if people were more connected to their fellow human beings, if we all felt more centred and fulfilled in our lives, maybe we would be pointing our cameras at a lot less social ills.

I'm a filmmaker who is known for these ambiguous portraits that tell multiple sides of the story without really telling the audience what to think.
