The nerds are the ones that make the films and do loads of other really cool stuff in their life.

I think Harry Potter's very important. Every opportunity I will get for the rest of my life, I would not have got if it wasn't for Harry Potter. And it would be height of ingratitude if I was ever anything but proud to be associated with these films.

All these things, social media or [smart] phones or the things that distract us from each other, are fairly new. They're all fairly new inventions, and I think we're in a stage where we sort of as a whole have gotten these new toys and we're just obsessed with playing with them. I feel like after a period of adjustment it will inevitably be a regression from where we are now.

I'm 5-foot-5, and I'll wear a big parka and put the hood up, and nobody gives me a second glance.

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 have no idea how much money I've got.

I love Steve Carell and Will Ferrell - they're my heroes.
