The filmmaker is not telling you what to think.

You have to remain open to the situation that you're filming otherwise you might miss the story.

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.

If people spend two hours thinking about the direction of their own lives and can relate to the stories they see on screen, to me that's a success.

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.

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.

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.
