With any kind of artistic thing, it's a muscle, like any athlete, and the moment you're not doing it, you lose all confidence. That's why I'm terrible with down time.

I definitely think that theatre is something I'll keep coming back to in my career for as long as I can. I also think theatre's something you have to be very fit to do. I am fairly fit, but I don't think I could do it all the time.

Also I just think I've been lucky enough to have great parents, and I've had good people around me who have always been honest with me, who would give me a purely metaphorical slap if I ever got too big for my boots.

I just got asked by another journalist 'Are you a feminist?' and I was just like... Is there a strange thing at the moment where you have to come out as a feminist? I've been asked if I'm a feminist so many times recently, and I'm just like 'Yes, yes, for God's sake, yes! Is there something that I give off that says I'm not?'

A lot of modern horror can leave me cold, and I'm not good with blood and gore and all that stuff. It's not fun for me. There's nothing entertaining about watching a film like that.

You have to find out who you are aside from what the media say you are. If you've become reliant on them for kind of a sense of self, then you're really screwed.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.
