I think if a character appeals to you, there are certain parts of yourself will come to the fore and other parts that will play down.

I think I was a bit frightened of having to be a grownup and tried to put that off for as long as I could.

Well, thing is, after they cancelled 'Zen', I didn't work for eight months. And in that case, it was not my choice. After I've done something that I'm really proud of and I think changes the way I'm perceived, the immediate reaction is: nothing.

At a certain point, I think, you harden yourself to the realities of the business.

Billy is a funny, cheeky, lovely boy and I love being with him. Parenthood is terrifying though. I can barely walk past a building without panicking that it's going to collapse on his head.

I think you have to draw from any character and bring it to yourself as much as possible.
