I don't believe in objectivity. I observe the observer's paradox every moment I'm filming. Your presence is changing everything; there's no mistaking it. And you have a responsibility.

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.

The world of extreme sports is also one of big business. Kids might think that snowboarding is the ultimate freedom, but this freedom is being marketed to them by commercial sponsors.

I have always been interested in garbage: What it says about us. What in there embarrasses us, and what we can't bear to part with. Where it goes and how much of it there is. How it endures. What it might be like to work with it every day.

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.
