I think creative people need to do a bit of, you know, tuning into every radio station - you just do, otherwise you don't know much about other people. You kind of have to learn a bit about yourself so you can work out how we all behave and why we do the things we do.

In theatre, there's the director, the writer, and below them the actor. In film, it's the actors who are most important. That goes against the grain for me.

That's the thing - you do a job like 'Shameless,' and suddenly that's why you can get a job like 'The Virgin Queen', not because of all the classical theatre you've done. But we can be very snippy about television. It's absolutely the most potent and powerful form of storytelling we have.

You just grow up and learn to think instead of just feel.

I'm a right pain in the hole for my agent. I won't take certain parts if I think they're offensive or banal. For instance, I won't do a film if I think it's full of violence for violence's sake, or a television drama if I don't think it's intelligent writing.

Healthy love, I always think, is... wanting the person you love to be more of themselves. And I think for a parent that's a challenge, because you have to let a baby spread its wings.

People can be a bit flagrant when they're having an affair. Most of the time, there's an element of it where they want to be discovered because they're in crisis. They need the boil to be burst, in some way, for a resolution.
