In Rio de Janeiro, every cop has to make a choice. He either turns dirty, keeps his mouth shut, or goes to war.

I don't actually like blocking actors. I prefer giving actors freedom. They don't have to step on a precise mark with me. Instead of giving marks to the actors I like to give marks to the camera.

Measurements, observations, descriptions can only be considered scientific when they are independently confirmed by other people.

We make violent cops, we make violent criminals, and no wonder we have shootouts in slums all of the time.

How can I make a movie about the violence of the police if the police aren't going to let me film it?

RoboCop the first movie was fantastic. But even if there was no movie, the concept of RoboCop is brilliant, first because it lends itself to a lot of social criticism, but also because it poses a question, 'When do you lose your humanity?

It's all about this abstract entity called the story. It's all about the best way to tell the story, and to make a movie about the issues that this story is about. Filmmaking is storytelling, for me.
