My fascination is not for cinema; it's for human nature and human beings because I find it quite difficult being one at times.

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.

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.

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.'

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.

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.

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.
