Everyone wants to be liked, so of course you want critical acclaim. After that, box office acclaim isn't bad. More than anything I think you have to try and make something you're proud of.

Sometimes the best set experiences make for the worst films. So, you don't want it to be too good an experience! But the bulk of your life is working with people and collaborating so you don't want anyone to be miserable on your film either. You want it to be something that people walk away from saying that it was a good experience for them and hopefully a good film. As a director, you are sort of leader of that troupe for that period of time, so you're aware of morale and your effect - how you are as a person and how that sort of trickles down to everyone else.

It's just nice to be able to communicate and be able to identify with a lot of different cultures. I have no idea what it would be like to be just one thing and speak one language. I feel enormously privileged to travel and be able to mingle and speak to people that, had I only known English, I wouldn't have been able to meet.

It's nice to represent to other people in the world that Americans actually do know what's happening in the world, can speak other languages and are conscientious. The perception quite often is that we don't know what's beyond our county line.

I don't know what I am on set. I can be many different things on set depending on how stressful a situation is. But at the end of the day we're making movies, we're not saving the world... we're not an army, no one's lives are at risk and we're just trying to make art, so I think as long as you keep reminding yourself that's what it's about you can have fun.

I think it's a fascinating thing to see how lonely people are in this world and what they're looking for. It's a universal concept. So, it's something that interests me and I'll probably revisit it if I get the chance to do the child soldier film because I think it's one of the most important scripts I've written. It's just too dark to do as a film right now. I need to do something a bit different.

In snowboarding, you're constantly aware that people are so technically brilliant at what they do, and you feel like, "Ugh, I'll never be able to do that."
