All you've got to do is turn up and have a few facial tics and be a lunatic and throw someone around the room or blow their brains out and people think it's good acting.

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.

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 would hate to be thrust into the middle of a big film and not deliver. There's young actors and they're put into these central roles and they're commanding armies - but they can't quite pull it off. I'd much rather do it in small steps and build it from there.

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.

I don't want to be disrespectful to people who are incredible at their craft, but the truth is, if I didn't get paid for it, I wouldn't act. The best-paying jobs are usually the worst films. You're a very small cog in a big machine.
