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

If you are in Brazil and you grew up in a right-wing dictatorship, you think Marxism is liberating. But if you grew up in Czechoslovakia, and the Soviet Union is controlling everything and killing people, then you think capitalism is liberating. Neither of those two things are true and it doesn't take a lot brains to understand this.

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?

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?

A lot of jobs today are being automated; what happens when you extend that concept to very important areas of society like law enforcement? What happens if you start controlling the behavior of criminals or people in general with software-running machines? Those questions, they look like they're sci-fi but they're not.

Pretty soon we'll have robots in our society, you're going to have a lot of automated processes that used to be done by people - this is happening. Society and technology is changing so fast, and the impact of the change on society and technology is global, not local.

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.
