I only went along to youth theatre with a friend when I was young to try to make myself a bit more sociable. But the whole thing was quite sore; it really hurt me trying to get into drama school. It was a world I knew nothing about - it was very middle class; all that usual stuff. But I was young, determined, and I just went for it.

Any kind of conflict draws me to a role.

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.

I was desperately shy when I was wee. Totally lacked confidence socially. When I look back at school photographs, I'm always the one shrinking in the back. What I really wanted to do was become a writer, and I don't think the residue of that has ever gone away. I still feel the ultimate achievement would be to write a novel.
