I was in the bath at the time, and my dad came running in and said, 'Guess who they want to play Harry Potter!?' and I started to cry. It was probably the best moment of my life.

My parents are left-wing, and I would describe myself as that. But also, you know what? I wouldn't describe myself as that. Because I don't have to. Because I'm not a political party. Most people are a little bit of each, and we change our mind on various issues.

Franchises aren't to be avoided. They can be exciting, and they give you opportunities to do other films.

When actors aren't filming they just go to their dressing rooms and relax.

I don't know why that is, but English politics is just so overly white. It's very much about the class structure.

I think part of me would love to play a drag queen, just because it would be an excuse to wear loads of eye makeup.

I still have issues around forgetting that it's my life and if I want to do something, I can do it.
