I know it wouldn't seem like I've had a lot of failure in my career, but there are things that I regard as failures, when I look at certain performances and go, 'That's not good enough.'

I don't think there's anything that I would really baulk at doing on-screen. I don't think so. I've got certain pet peeves about writing... my pet peeve about reading scripts is when they give you a line reading and there'll be a line but next to your character's name it'll say 'very angry'. But I'm like: "Well, I'll decide that actually!" So, there's little things like that. That's a slight pet peeve.

That's what fame does to you. You acquire another self.

Some people are asking me questions like this is a more shocking subject, which is so strange.

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.

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.

One of the things that I cannot fathom is young actors who will not audition and won't read.
