'Biutiful' is a tough film. It doesn't make concessions to the vulgarity of light entertainment. It's not the kind of film that you see every day in the Cineplex. But as an artist, it's the thing that I needed to do.

As a city, it is always compelling. But every day in Mexico City, I give thanks that I am alive.

It's more enjoyable for me to know that life is finite. Knowing that, I would like to go to a party. 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.

I see only one requirement you have to have to be a director or any kind of artist: rhythm. Rhythm, for me, is everything. Without rhythm, there's no music. Without rhythm, there's no cinema. Without rhythm, there's no architecture.

Ultimately, with every film I'd done before, there was a reference. They have their own uniqueness, but there was always a precedent.

To make a film is easy; to make a good film is war. To make a very good film is a miracle.
