Robert Rodriguez, makes a feature film in 35mm celluloid one and a half hours long, and nobody believed him, I think he wrote a book about it and gave all the details of how he spent the money, even making a 35mm celluloid feature film was possible, at least for Rodriguez.

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.

I am somebody who creates images, with my perspectives, fascinations and my instincts as a narrator. You have to activate the audience's imagination. If you are just giving them scientific results, they would forget the film in five minutes flat.

That shot in "Into the Inferno" somehow popped up while my editor and I were viewing the footage. I immediately said, "That looks like the opening shot because the camera approaches the action very slowly and we have enough time to insert some of the main credits into it." So it was a practical choice. At the same time, you see these tiny figures standing at the rim of something, and all of a sudden, the camera rises further and you find yourself looking straight down into an inferno.

You have to realize that, about 20,000 years ago, there was a cataclysmic event when an entire rock face collapsed and sealed off the cave. It's a completely preserved time capsule. You've got tracks of cave bears that look like they were left yesterday, and you've got the footprint of a boy who was probably eight years old next to the footprint of a wolf.

I know for sure that there is only one step from insecticide to genocide.

The universe couldn't care less about us. I say this very clearly in the film [ "Into the Inferno"]: our planet is "indifferent to scurrying roaches, retarded reptiles and vapid humans alike."
