I like some superhero movies, but I have to say that they all feel the same to me. I've seen them a million times. They're all the same movie.

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

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.

If you replace a soldier with a machine, you take away the possibility of the soldier or the policeman to not do something the state asks of him. He may think it's unethical to do it. A machine doesn't have that critical perspective.

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?

Television is so cool. Television is proving that we can be sophisticated and that people will watch, if it's good.

Either you look back and deal with your hypocrisy, or you dismiss it.
