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

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.

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

Some documentaries are made by people who are driven more by one particular story, or have different backgrounds or ambitions, but I'm always looking for projects that let me be the best filmmaker I can be, and to be stretched and grow further.

There's a theory of accidents that I studied when I was making a film about nuclear weapons: you can never eliminate accidents, because the measures you introduce to prevent accidents actually produce more accidents. That's certainly true of this sport; you're flying over 40 feet of what might look like snow, but it's hard as ice, it's as hard as pavement. You're doing acrobatic spins and tricks, 40 feet above pavement, essentially. There's been more accidents since, and there are going to continue to be more accidents, that's the nature of the sport.

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