I mean, "The Jinx" is an amazing piece of cinema and amazing television moment, it`s rare documentarians can feel the direct impact of their work.

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.

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.

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.

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 felt like the universe was tapping me on the shoulder saying, "You're the guy who has to tell this story because nobody else is."

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