The art world can be very intimidating because it's just so vast. You talk to people who are really clued in to all the young artists and coming into it you're never going to be able to catch up immediately, even though there's pressure to.

I don't think that you necessarily need a certain type of background to take on roles. You see actors from very, very privileged backgrounds playing working class characters and vice-versa. I don't think your background limits you as to what you can do.

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.

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 think any actor worth their salt wants to show as much versatility as they possibly can.

The most wonderful thing I hear is people coming up and saying 'Thank you for my childhood', which still blows my mind but is very sweet.

There were a few years there when I was just so enamored with the idea of living some sort of famous person's lifestyle that really isn't suited to me.
