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 filmmaker is not telling you what to think.

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

Any documentary; any capturing of a non-fiction event, is a hyper-realistic condensation of reality that hopefully reveals an emotional truth. It's never the actual literal truth of an event.

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.
