I really believe there is the possibility of something great that can happen in the right hands.

I love that process in which there is no safety net. Then the actor also can allow mistakes, because there's no such a thing as a mistake. You're working with good actors, that thing that starts as a mistake becomes actually the life of what is going to follow in the scene. I find that it is fantastic, and for me it is easier than for the actors.

I have to say, 'Gravity' is better in 3-D, even though in 2-D the quality of the picture is better. But the 3-D is better.

When you work with kids, people tell you to be very delicate, but that's the last thing you should do with kids. They feel patronized if you're like that. They just want you to be normal.

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.
