You're looking for the best way of shooting it, but sometimes the best way of shooting it is changing the script.

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

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?

As it turns out, what looks like science sometimes is not.

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 have to be clear with myself and very conscious of what I am trying to say. Misunderstandings will always take place; it's unavoidable.

Usually I say I have no imagination.
