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.

As an actor, there is room for a certain amount of creativity, but you're always ultimately going to be saying somebody else's words. I don't think I'd have the stamina, skill or ability to write a novel, but I'd love to write short stories and poetry, because those are my two passions.

I've been working since I was 9, and I've never known a life without a film set.

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.

It's really good to talk about it [ hydraulic penises and prosthetic butts], and it's very gratifying when people ask us about the other aspects of the film [Swiss Army Man], but [those things] are part of the movie and they're important and hilarious, a very fun part of the movie, so there's no sense from us of not wanting to talk about that. I think it's exciting that those things exist in a film that is also very heartfelt and emotional and profound.

What I love about the gay thing is that every single person I type into Google, it doesn't matter if it's Florence Welch, anybody, if you are not being called gay you don't have a career. That's my theory!

I don't want to say I'll never play someone with a cockney accent, but I think I would be irritated by me doing it.
