I love making fiction films as well as nonfiction ones, and hope to keep challenging myself to make better and better work.

I don't know if people realize how hard I work, because sometimes people ask me for my secret. The truth is that I don't have any secrets apart from the fact that I've been directing theater and film for twenty years and trying at every stage to make my work better.

I love great locations in movies, and I couldn't believe I'd never seen a landfill on screen before. It was the most haunting place.

I've always been a fiction filmmaker and I've been heading in the direction of fiction filmmaking, doing documentaries along the way.

I'm not an expert on how to configure the sport, but I can observe and say that accidents seem to be a part of it. The athletes are incredible, with the courage that they accept the risk of death, paralysis, and brain injury. These are really life-changing, life-threatening injuries, and the risk is extremely high.

I am riveted by extreme sports like big-wave surfing, 'megaramp' skateboarding and half pipe snowboarding. I am fascinated partly because the sports are so exhilaratingly acrobatic. But I am also captivated by the fear that a terrible accident might happen at any moment. And accidents do happen.

With portable cameras and affordable data and non-linear digital editing, I think this is a golden age of documentary filmmaking. These new technologies mean we can make complicated, beautifully crafted and cinematic films about real-life stories.
