I have worked for YouTube like texting and driving because I was curious to test what's out there and how does it function, can I release something like about texting and driving to very young audiences, at the age where they do their drivers test? And the response was phenomenal, millions of people saw it.

I went to volcanoes where I knew that there was a lot of mythology around them; there was something like the creation of gods and monsters and demons.

We live in a society that has no adequate images anymore, and if we do not find adequate images and an adequate language for our civilization with which to express them, we will die out like the dinosaurs.

We have volcanoes also in our immediate neighborhood. I wish we didn't have to travel that far. Probably the kind of magnitude and awesome raw power of them is very fascinating, and of course it's very cinematic.

Ten years ago in Antarctica shooting "Encounters at the End of the World," I met a very fine volcanologist from Cambridge University [Clive Oppenheimer] and we kept talking about doing a film and all of a sudden it became serious when he hinted at the possibility to film in North Korea.

I think a state should not be in the capacity of killing anyone with the exception of warfare.

There is a fascination about crime, which is understandable, but hardly anyone talks about the families of victims of violent crime and the devastation that is beyond the victim alone.
