Film is not the art of scholars, but of illiterates.

I have a great map of the Tibesti Mountains in the southern Sahara or Northern Chad. It's a dream of mine to go there, but it's such a volatile area, you have to be prudent.

I think Irish people started to move to the United States - many things that were of consequence. And it was a tiny and mild event compared to what had happened 74,000 years ago.

All of a sudden it's twelve-year-olds who are contacting me, fifteen-year-olds, and they have very, very fascinating questions. However, they speak in a language of their age group which I have to learn first.

For a film I shot on the most difficult mountain on God's wide earth in Patagonia for a sequence where there was high probability some digital effects were needed, somebody made storyboards and I quickly ignored them, after half an hour I ignored them and I never used any digital effect.

Facts sometimes have a strange and bizarre power that makes their inherent truth seem unbelievable.

I work very fast and steadily, and I don't hardly ever notice that I'm working. It feels like just breathing or walking when I do films.
