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

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

How do you make RoboCop? How do you slowly bring a guy to be a robot? How do you actually take humanity out of someone and how do you program a brain, so to speak, and how does that affect an individual?

It's easy to make a pirate copy when you have digital tapes of things. And it was so complicated and complex to go through all the post-production of a movie without ever going digital.

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.

I come from a documentary background and my natural tendency, as a filmmaker, is to make a movie, if I have something to talk about. If it's not about anything that matters, I don't feel like doing it. I'm not against people who make movies just for fun, but I'm not one of those guys. I just want to provoke thinking and debating about certain issues.

No wonder we have a lot of violence in Rio: the corrupt and violent policemen meet the violent criminals in the streets. What else is going to happen?
