Really, I'm a neurotic perfectionist. Every single word in the script is the one that I want.

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 think every beautiful tale in the world hides the truth and reveals it little by little.

When people laugh and applaud as characters are killing each other, and you never see the body that's lying there, or you never see the family that suffers, then it turns into a cool thing to do, like a videogame. Then, when you watch the news and see that 15 soldiers were killed, you start to see them as just numbers, material, information, images. We lose the real weight and real value of one simple human life.

Of course, there's always one theater that shows some kind of European film. Now, fortunately, you have DVDs, so it's possible to get anything you want within a few hours. In those days, it was virtually impossible to get Italian films, or German films, or whatever. So I grew up with very standard, mainstream films.

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

In the creative process, my ego has always been a huge tyrant ... a dictator and kind of rude and very misleading, because sometimes when I'm doing something, I say, "This is great! This is fantastic! Very genius!" And 20 minutes later, I feel like a dead jellyfish. "You are a stupid a**hole. This is a piece of sh*t. Nobody will care about it."
