Because I'm short and slim, I can identify with somebody who's an unlikely fit for something and desperately wants to be part of it.

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.

I think honesty is the most heroic quality one can aspire to.

What I learned is that acting is to a large extent about trying to stave off self-doubt long enough to be natural and real onstage.

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.

I'm possibly a very morbid person but I think about death a lot.

I'm quite confident, but I don't fancy myself. I don't really care about how I look.
