You have to be very focused about the music that you have inside.

Y Tu Mama Tambien' is one of the first unrated movies to be nominated for an Academy Award for Best Original Screenplay. But many video stores won't take a movie that's not rated, so I had to make the movie an R.

It's a cliche, but Americans are puritanical. In their movies, they are scared of sex, but they overindulge in violence. I could have cut a G-rated version of 'Y Tu Mama Tambien' that would have pleased the American ratings board, but it would have been five minutes long.

I left Mexico for artistic survival. If I had stayed, I would have been forced by the government, who control the movie business, to direct TV shows or commercials or infomercials for the government.

The long takes process doesn't allow for that many takes. In the past I have shot over 50 takes of different shots. Sometimes you end up using take 64, sometimes take four.

A budget is not an issue. I mean a budget is used if you need more weeks or more time or more elements, but the creative process is exactly the same. In some instances you become more of a boss when you are doing a small movie. So that is not so relevant. The only thing is that the bigger a movie is in terms of budget, is that there are more people giving opinions.

The great thing about the moon landing is that my grandmother got the first color TV in order to be able to see the moon landing that was in black and white.
