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.
I had a good time working with Russell Crowe, Ron Howard and Ed Harris. It was a great cast and Russell worked really hard, doing tons of research and questioning everything
