I remember when the Berlin Wall fell and suddenly intractable problems get solved.

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.

The world needs more women filmmakers, so we have to keep encouraging ourselves and one another, and eventually things must get easier for us.

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 the big businesses. Kids might think that snowboarding is the ultimate freedom, but this freedom is being marketed to them by commercial sponsors.

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