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.

Chevron has wrapped itself in some pretty good arguments that make you scratch your head. The moral responsibility is certainly at its door. I leave it to other people to figure out whether there's legal responsibility.

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.

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.

Life is much more complex than the black-and-white sound bites that you get on television. There are nuances and shades of gray.

I like to blow up stereotypes, like taking the icons of metal, the epitome of male testosterone and showing them as regular people.
