I think it's kind of great, to be honest. I'll never do another film [like Swiss Army Man] where I get to talk about those things, so I might as well enjoy it while I can.

I was in the bath at the time, and my dad came running in and said, 'Guess who they want to play Harry Potter!?' and I started to cry. It was probably the best moment of my life.

There's no shame in enjoying a quiet life. And that's been the realization of the past few years for me.

When you're seventeen to early twenties, that's the time you're trying to work out who you are. If you're trying to make some kind of artistic or creative impact, that's the age when you start to figure out how to do that.

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.

To be fair, it's not even the first time I've seen a dead version of myself. There was one on Harry Potter, on the last movie, that they actually used to bring to set in a body bag.

Paul [Dano] was amazing at carrying me around [in Swiss Army Man]. I wanted to be there as much as possible but didn't want to hurt Paul's back, but Paul often chose me over the dummy many times on the set. But yeah, to be honest, a little bit of preparation I did with my friend in my flat could never have prepared me for quite the level of physical reliance we would have on each other.
