The way America sees Mexico, if they have any sense of it, is like Taco Bell. Our countries are neighbors, and the only hard food to get in America is true Mexican. It's impossible to find, even in L.A. Why is that?

I was aware of the possible biases you could get as a commercial director, like being too concerned about the technical aspects of the form rather than anything of substance. If you keep working in commercials, you can get trapped in a very superficial way of thinking. I always used commercials as an exercise for filmmaking, like going to the gym.

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.

I remember, the first time I saw a [Andrei] Tarkovsky film, I was shocked by it. I didn't know what to do. I was fascinated, because suddenly I realized that film could have so many more layers to it than what I had imagined before. Then others, like Kurosawa and Fellini, were like a new discovery for me, another country.

One of the reasons why I agreed to do commercials is that they gave me complete freedom. I just had to have the car in it and write a story around it. I wanted to do something serious set in a Latin American country, but again, it was an exercise in style for me.

I think movies in general should have more respect for the audience than they do. Too many films are afraid to confuse people, so all the information is given to them right away, and there's nothing left for the film to do. It ruins many stories, because everything becomes obvious and predictable. I want my films to engage people more and make them more actively involved in the story.

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