I made commercials for corporations like Volkswagen and Coca-Cola, but I was always the one to write them, too, which was a very good exercise, because I learned to tell little stories.

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.

I personally can't handle frivolous violence. I overreact to it.

You hear about bombings in other countries, or numbers like "10,000 people died" - you hear that number and you think, "Well, I saw that yesterday in a film, and that didn't look so bad." Younger viewers, in particular, lose perspective on reality.

I was a street kid, basically. But really, Mexico City has always been this big, complex monster of a city that has always had real problems and needs, and I've always found my way through it in different ways.

When you get to the holidays, if you think that the holidays will be forever, you just take it for granted. But, if you know that you have just three days at the beach, you will be so happy to be there, every day.

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.
