You must live life in its very elementary forms. The Mexicans have a very nice word for it: pura vida. It doesn't mean just purity of life, but the raw, stark-naked quality of life. And that's what makes young people more into a filmmaker than academia.

For me, the distinction between documentaries and feature films is not so clear - my "documentaries" were largely scripted, rehearsed, and repeated, and have a lot of fantasy and concoction in them.

I try to be after something that is deeply reverberating inside of our souls, some deep echo from - even from prehistory. What makes us humans? How do we communicate? Where are we going at this moment? Something for an audience where they can step outside of themselves, where they can be almost like in ecstasy of truth, some sort of deep illumination. And that's what I'm trying in documentaries and in feature films.

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.

It has always been my aim to find that sort of passion and figure out how to transform it into cinema.Timothy Treadwell's footage was almost like a diary, and he had always dreamt of becoming the movie star in his own gigantic production.

It happens sometimes that the material itself carries things you have not fully planned. The footage has its own right, its own life, its own vibrancy and energy in it.

It's not because nature is angry, it's rather that we are stupid. We're not doing the right thing with our planet.
