I don't want to make films that give you the answer. If there is a message to my films - and I hope there isn't - it's to be open-minded.

I am an obsessive flyer, myself.

And as a director, you make 1,000 decisions a day, mostly binary decisions: yes or no, this one or that one, the red one or the blue one, faster or slower. And it's the culmination of those decisions that define the tone of the film and whether or not it moves people.

I went to college, I went pre-med, I thought I was going to be a doctor.

When it comes to casting, I've been so lucky. I've worked with unbelievable actors who make me look better than I am and take the written word and make it honest.

Filmmaking is finding a piece of granite and you start to chip away and then you have the shape of a head, the shape of the arm, you can see the shape of the face and the face starts to gather character. You have to find it.

Most people see a documentary about the meat industry and then they become a vegetarian for a week.
