In a way, I managed to get the deepest things, the best things out of people. That's why I'm a filmmaker. If you don't have it in you, you'd better do something else.

My non-fiction films are pretty much fiction, or at least close... It's all "movies" for me. I never have searched for a subject. They always just come along. They never come by way of decision-making. They just haunt me. I can't get rid of them. I did not invite them.

Otherwise you have to repeat a lot when you're filming. And I've seen the film and it's in a border town in Mexico close to the border with the United States, so of course you have a lot of traffic and noise and dogs barking right nearby, and for that you have to repeat a lot and Robert Rodriguez didn't do that. Smart, smart, smart, you better have smarts also.

I looked, for example, to certain types of literature to which I would like to refer, like The Peregrine by J. A. Baker, and I mention a book, "read this, read it, read it if you are serious of being in any type of art or into filmmaking," or films that I should quote as examples.

Similar thing until today, with digital cameras you look after something like that as robust as they can be.

It was a subject [ volcanoes] that was dormant in me for a long time and it popped up 40 years ago when I made a [short] film on the Caribbean island of Guadeloupe about a volcano that was about to explode and a single farmer refused to leave ["La Soufrière"].

I have been in lots of very intense life situations. I have been shot at, and I have been hungry, and I have been in solitude, and I have also briefly been behind bars. So in a way, I know the heart of men.
