And what I like about it is it makes me happy and I think it makes a lot of people happy to go to the movies and to not think about the problems of the day or the problems of tomorrow or the yesterday and just go on for the ride and have the fun of losing oneself in a fantasy.

Often you hear stories about never working with children. I disagree because children still have that residual magical thinking. They haven't had their imagination knocked out of them by turning into adults and life experiences.

Feel like real time unfolding. It's going to smack of reality and feel as real as it can ... The buildings themselves aren't (shown) ... The movie's about what happened amongst this handful of men when the buildings came down.

It may come as a surprise to people, but I'm actually quite boring and normal. What do I do? I read books. I drive my kid to school. I have lunch with my wife. I pick my kid up from school. I go home.

I've gotten pretty good at leaving characters on the set. I go home and try to relax and regroup and be ready for the next day.

I want people to discover my movies, and however they choose to receive it is their business.

Most of my favourite moments in film have been when I've had an opportunity to say something from scratch, something original, whether I jotted down a few lines or it came out in improvisation.
