I always think politicians and even my dentist have more egos than actors.

Mexico City is very different now than when I grew up, but I was in the streets all the time - though I was born to a middle-class neighborhood where there weren't a lot of gangs and things. I was always comfortable.

Life and death are illusions. We are in a constant state of transformation.

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.

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.

There's nothing better than being in a film that translates to audiences and makes people think and feel good and walk away with great revelations in their own life of some kind. But when the process and the experience and the fun of that matches, it's a good feeling.
