And the biggest improvement I see between 'Up in the Air' and 'Juno' and 'Thank You for Smoking' is that 'Up in the Air' deals with the complicated human stuff in a way that my other films have not. It's a more articulated film, and because of that, I'm most proud of it.

I'm a believer that people need to understand that filmmaking is not a perfect process for anybody. It is a process in which you find the film and the film finds you. And that is every film.

'Alien' asked ground-breaking questions about eco-politics and female empowerment. 'The Matrix' delved deeper into the concept of perception versus reality than perhaps any other film I know. But for some reason, we tend not to remember the significance of their writing.

I used to have a group called Bad-Movie Saturday. Every Saturday, six of us would go see the worst movie that came out each weekend. It'd be noon in Burbank. It was just a running commentary. All executives - we would each talk through the movie and make jokes.

'Looper' is about what your 55-year-old self would tell your 25-year-old self over a cup of coffee. It's about finding love in the third act of your life. It's about overcoming trauma and the idea of true sacrifice.

Everyone wants to be loved; everyone wants to know where they're going in life; everyone wants to have a sense of direction and feel the next day is going to be better than today. We just all deal with it in a different way.

My writing voice is very much like 'Thank You for Smoking.' It's a guy's voice. It's very masculine.
