To the children who loved Harry Potter, I want to say your enthusiasm was the real magic. I so enjoyed being on the journey with you. And to the adults who bought the Harry Potter books and devoured them, I just want to say, those books were for children.

My taste in the films I've taken as an actor is similar to what I'd do a director or writer: all quite odd, challenging stuff, slightly off-the-wall.

As an actor, I think sort of relish the chance to take a leap and sort of put yourself out there. You know, it's, like on any film, you just have to be willing to embarrass yourself, because otherwise you are not going to really reveal anything that you have. So I think it's exciting.

I was worried on a personal level because I wanted to be slightly taller than I am, ideally. But I've now accepted it. Basically, I came to the conclusion a while ago that you can either be really bitter about it or you can make loads of funny jokes.

Both of my parents have been actors; there were a lot of show tunes on in the car all of the time. I grew up with that.

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 used to joke I was a point-and-click actor. My whole process has been about trusting your instincts and hitting your mark.
