With directors, some have a kind of in-built ability to just know how to work with actors and get the best out of actors, and some don't have a clue about acting. I think it'd be a good idea if directors put themselves in front of the camera, or even went on a six-week drama course, just to know a little bit about what that feels like.

I think it's a shame when the arts have to suffer because of corporate greed. People will always strive to make film, and the only important thing is that we keep trying to make ourselves heard and keep making our films, no matter what the climate is.

There's no social realism in 'Tyrannosaur.' It's not about the social landscape or the political landscape or any of that. It's just about human beings. I never made 'Tyrannosaur' in reference to anybody - I just made it because I had to make my own films.

It's such a stressful environment, I find, being an actor, being put in the chair and "Touch this, that, and the other," it's too much for me. I find it hard to tolerate that sort of stuff. If you're not enjoying it, don't do it. You're wasting everyone's time.

When you're having conversations about actors, you realize these same conversations have happened about you. If you want to make a film for $5m, then you cast A, B and C, but if you want $20m, you won't be able to cast them, you need X, Y and Z.

I got through with my ability to mimic others and make people laugh. I swaggered through life, but, in reality, I lived in fear pretty much every day. I acted like a completely normal person, and I suppose I was good at it. But, inside, it was a very different story.

What's my dilemma here? Am I making entertainment or am I making art? What am I saying? At the end of the day, cinema is entertainment for millions of people, but for me it's expression.
