My country has been wracked with violence for a long time. Just to see all the violence on the news makes you sick. It's true that violence is in our nature, but I try to explore deeply where it comes from and where it goes and what it creates. Not in a moralistic or preachy way, but just to observe the real consequences of violence in a human being or in a society.

The actors make the film. They're the ones that take this theoretical movie that's in your head and make it real. The success of a film is entirely on their shoulders. I admire them, because acting is such a difficult thing to do, and I personally can't understand it.

Every time that I'm challenged with a film I think that I haven't learned anything, that every film is different and that every thing that I have learned is useless in this new adventure.

How can [actors] learn their lines and be honest in front of 30 people and all the lights? It makes me cry sometimes. I can't understand how they can be joking with me 30 seconds before, and 40 seconds later they're giving me all this incredible feeling.

I think the arts should get big support, but my country has a lot of needs more important than film. Medication, education, food... The poverty is overwhelming. There are simply more important things to be attended to.

When I went to university, I finally got exposed to European films, and they had a strong impact on me. I felt those films had a lot of things to say that weren't getting expressed in the films I was used to seeing.

As a sensitive filmmaker, I think you have to really be careful in how you explore it. Not that you can't tell any story you want - I'm not calling for censorship or anything. But if you're going to have violence, I think it's important to deal with the consequences of that on a human level, not just to make people laugh.
