If you’re purely after facts, please buy yourself the phone directory of Manhattan. It has four million times correct facts. But it doesn’t illuminate.

The trees are in misery, and the birds are in misery. I don’t think they sing. They just screech in pain. …Taking a close look at what’s around us, there is some sort of harmony: it’s the harmony of overwhelming and collective murder.

We haven't seen a real volcanic event at least in 74,000 years - [Mount Toba] in Indonesia, in Sumatra, where the crater itself is 100 kilometers across. It was so monumental, what happened, that for a very long time the entire atmosphere of our planet was darkened. It's not the lava and the heat per se; it's the obscuring of the entire atmosphere, and it made it very difficult for the human race to survive.

Roger Ebert was a very valiant soldier of cinema who passed away, and we miss him. It's over with serious discourse about cinema in the print media and on television. It has been replaced by celebrity news. So we are speaking in his spirit always.

Without dreams we would be cows in a field, and I don't want to live like that. I live my life or I end my life with this project.

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.

Perseverance has kept me going over the years. Things rarely happen overnight. Filmmakers should be prepared for many years of hard work. The sheer toil can be healthy and exhilarating.
