I take things in better when I'm allowed to talk, and respond, and engage and move around a bit.

I love just going out and sitting down in the park along with the thousands of other people who apparently have no work to do during the day. People come up to me, but they are generally really nice. New York makes it easier, for me at least. People manage to be enthusiastic and sort of sane at the same time. And that’s lovely.

I'll miss some of the opportunities that playing Harry [Potter] brought me.

I would like to initiate an initiative - the Broadway Annoying Audience Member Relocation Programme.

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.

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

Everyone on the set has a mobile phone, and I found by pushing a few buttons, they could be programmed into different languages. I fixed Robbie's Coltrane to speak in Turkish.
