The thing is, if I try to talk about acting, I come off as moaning. But I'm privileged. I think it's all about control. Acting is vulnerable because you're not in control of anything. You have to give up a lot of your trust; it's up to somebody else what they do with what you've given them.

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.

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.

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.

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.

I live in a state of hypersensitivity, and I've always had this feeling that something bad is going to happen to myself, or my wife and children. This manifests itself in different fears and visions.

You walk past people in streets, or they serve you in shops, and you know nothing about the horrors they may be living with.
