There is nothing worse than when actors come to a set - and it happens a lot with big stars - and they are too aware of where the camera is. They are the show. And that becomes apparent and it affects the production. I am like 'You should not know where the camera is - you should act, and I will do the rest.'

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.

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.

I could never sit down and say: I'm going to do an out-and-out comedy, just to prove to people I can. You've just got to do what you do. Just listen to your soul and do your art and do it for the right reasons, and then you can't fail.

At the end of the day, my life isnt about other peoples work. Ive got to stop giving stuff away. Ive got my own stories to tell, and a great need to tell them. Ive got these images, these thoughts in my head, and I need to find a way to cope with them.

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 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.
