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.

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.

I can't afford to step away from acting, but the one thing I've learnt after all these years is that I don't fit in. It's very difficult to be at the mercy of other people's whims and visions.

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 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.

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.
