We sing a lot of the soundtrack in this film [Swiss Army Man] - me and Paul Dano - and on the last day of filming we had to just get into the back of our sound mixer's van and record a really crappy, rough version of the singing then. For some reason that was one of the most fun days.

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

My friends have always called me 'Mr. Thorough,' in that when I get into something, I become obsessed with it.

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

I don't want anyone to ever say that I don't belong where I am.

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.

I definitely think the idea of friend zone is just men going, 'This woman won't have sex with me.'
