Celebrity's a pain in the backside - you're always on display.

I never went to acting school. I started in the circus, music hall, I was in a group, did kids' bits. I've always had this kind of insecurity being uneducated.

The urge to act became the overriding force in my life. It thrilled me. There's a moment with acting when you're in the groove, and you and what you're trying to do are seamlessly one. That happens sometimes, and I'm really happy it can happen to me.

I was concerned about doing the right thing when I was a kid. I suppose as a child, you're a massive egomaniac, and you think that everything you do is going to affect the world.

I'm entirely uneducated. I went to public school - public in the American sense - a blue-collar, working-class school. I never got a scholarship, I left when I was 15, never did any exams.

I was a closet straight. I think I wanted to be gay because I thought it was arty and interesting. And also, I was phenomenally shy with girls.
