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

I like to give dimension to shots inside action scenes. It's demanding because you have to rehearse a lot of things happening at the same time and frame all those things in a shot. But I feel like when you accomplish that then you've got a cool action scene.

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

Well, I'm not that popular with the politicians, I have to say.

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.

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

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.
