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.

I understand when there's no money for the arts in the government, but it should maybe pressure private companies to support more filmmakers. These exhibition and distribution companies are huge, and there might be incentives for them to invest more in Mexican cinema.

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.

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.

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've listened to music all my life. I've always felt that music tells more stories sometimes than films, with more possibilities. Every time you listen to them, songs bring different images and moods - depending on where you are in your life, you can listen to a song and it means something different.

I like to make films, but the only reason I do is because I'm a very bad musician.
