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.

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 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.

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.

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.

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.'

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.
