The sixth Harry Potter film - I don't like my performance in that film at all.

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 might like to be an actor, but there are loads of other things I'm interested in as well, like music and writing and sports. I want to keep my options open.

In some ways, you get to find your voice better in [a sequel] because you have to define how you're doing it differently.

I'm sure when I have a nostalgic, teary moment in 10 years time, I'll try to put the glasses when I was 10 on and cry to myself in front of the mirror

I just have this fear that I'll get on stage and there'll be that brief moment of adrenalin and I'll forget my line.

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.
