For the first two movies, I had a huge crush on Tom Felton. He was my first crush. He totally knows. We talked about it - we still laugh about it. We are really good friends now, and that's cool.

Really I was open-minded about doing anything, but the one thing I didn't want to do was get myself into a corset, because I was worried I'd never get out again.

What I find difficult about photo shoots is the line between playing a character - you're being asked by the photographer to take on a role like you would in a movie - and being a fancier version of yourself. It's about finding that line between being spontaneous and open to direction, but also trying to explain to photographers that the "me" is often taken out of context because it has all of this other stuff attached to it.

My grandma said - when I was really young and I'd sing along to the radio - why do you sing in an American accent? I guess it was because a lot of the music I was listening to had American vocalists.

I think that why the research and the data are so important is because you become so used to seeing the world one way that you don't even notice anymore. [Gender inequality] has this invisibility.

Jodie Foster did it, Natalie Portman did it. I think it's entirely possible to juggle university with filming... I actually think going to university will make me a better actress. The experience of living like that, working to deadlines, living with other students. It's all the things I want. There are actresses who don't know about things like doing their own laundry and getting a bus. I'm not going to be like that. For me, this is just the beginning. I've only shown a little bit of what I can do. There is so much more to come.

I can be 100 years old but I will always be proud to say I was in Harry Potter.
