I remember being in Dublin in a café and seeing him [Jack Gleeson] two or three years ago, and he came in - Joffrey[from the Game of Thrones] came in - and I remember being so star-struck. I don't like famous people and I don't really get star-struck. But I remember seeing him and being so impressed that he was walking around. So I really like Joffrey.

The Jemaine [Clement] and Taika works is a very long and slow machine - we put an idea in one end, and it takes about six years to come out the other end. And sometimes it doesn't even come out. And sometimes it comes out as a different idea. So we've out the idea of We're Wolves into the machine, and it's now slowly going through the sausage maker.

Also with that money comes the idea, "Let your imagination run wild." Which I think is a very dangerous thing. I think it's dangerous because you can get into pretty wacky territory. There are things that are too crazy.

When you're actually making a film, it's just people on your back all the time wanting stuff and you're constantly having to it deal with them. It's probably the most time consuming of all the arts, but I do love it because it is a great mix of visual art and music and writing.

I have to keep reminding myself that I was hired for a reason and one of those reasons is because of the stories I tell and the films I've made previously.

With a feature film you're dealing with so much more money and you've got to be very aware of the fact that you're really working with an audience. You've got to have a relationship with the audience. Play with them and show them things you want them to see.

Sundance felt like a natural fit. I love coming here, and I do think that this festival suits my films rather than most of the festivals I've been to. I'm not going to Cannes, you know.
