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've never watched my films with an everyday audience so it was really crazy to watch people clap at the end of my film - with no one there, no actors, no people from the film. It was just a spontaneous reaction, so I thought that was probably the best compliment you could get from an audience.

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.

I started writing stories when I was 9 or 10. I wrote my first screenplay-type document when I was 14.

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.

If you really want to tell someone you love them, you don't just go and blurt it out. There's a dance. And your movie does that.

The theoretical casting part of movies is the funnest part. You really can imagine so many different versions of a story, based on who's embodying it.
