Once Now You See Me proved that that tone could work, which I'm sure was a nightmare for them in post - is this too serious? Do we have to say that magic really does exist or not? - I can take that and have fun with the tone that they established.

I've worked every day since I was 10. I don't know how to do anything else. There is nothing else I'd rather be doing.

I'm possibly a very morbid person but I think about death a lot. I don't know if it's maybe from being on films that's often playing Harry [Potter] or I just think it's a natural thing that I have. It's something that I think about just because it's fascinating in a very alien kind of way.

It's important to say that the more challenging a scene is, in a way, the more fun it is because the more of my job I get to do.

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?'

Being in Harry Potter is like being in the Mafia. Once you are in, you are never really out.

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