It's all movies for me. And besides, when you say documentaries, in my case, in most of these cases, means "feature film" in disguise.

You can't have a helicopter fly over boiling lava. It would've exploded from the heat, and is just way too dangerous. The pilot of a helicopter would've flatly refused anyway.

I couldn't roam wildly and speak secretly with villagers [in North Korea]. No way you could do that. And honestly, I didn't even try. I was realistic of what I could do and yet persuaded them into accepting numerous things that I shouldn't have filmed.

Most of the volcanoes are pretty far away. You have to go to, God knows, Alaska. Or you have to go to the Southern Indies or you have to go to a specific island.

Spirit of immersion and curiosity and awe and participation is something which Timothy Treadwell and I have in common.

I don't want to travel.

I make films because I have not learned anything else and I know I can do it to a certain degree. And it is my duty because this might be the inner chronicle of what we are. We have to articulate ourselves, otherwise we would be cows in the field.
