Some things are just really difficult to do. That's what I find hard. I usually can find a way to do a character to make it real and work. But sometimes it's a struggle sustaining that, because there's such a level of personal involvement and personal, physical, and emotional distraughtness.

I'd been depressed before, of course. But I'm talking about really depressed. Not just feeling a bit down or sad, a depression that has something to do with biorhythms. I'm talking about the kind of depressed that floats in upon you like a fog. You can feel it coming and you can see where it is going to take you but you are powerless, utterly powerless to stop it. I know now.

My mum always told me I was precious, while my dad always told me I was worthless. I think that's a good grounding for a balanced life.

I actually find in America, there's a slight snobbery about actors who go back and forth between big heavy dramas and popcorn fare. That always intrigues me, because that doesn't exist in the same way in Britain. And I imagine it would be worse. In terms of the sort of class, and the sort of snobby, slightly on the back-foot thing Britain has. But it's much more prevalent in America. I'm really intrigued by it. I don't know why that is. But I'm aiming to break down those barriers by being in a Shakespeare film and a Smurfs film within six months of each other.

Nowadays people don't know how to handle it if all the ends aren't tied up and they're not told what to think in films. And if they're challenged, they think it's something wrong with the film.

I was horrified when Richard Chamberlain and Rupert Everett said gay actors should stay in the closet. They were saying to people that they should live a lie and not be liberated, to live in fear of being found out.

I come more to Scotland than I ever used to, so I feel more connected to it, more part of the zeitgeist. You know when you realize you have a choice and I'm choosing my homeland. It's funny: when you get older these things creep up to you.
