I have no idea how much money I've got.

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.

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.

If I die on a film set when I'm 80, I'll be happy with that.

I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!

I take things in better when I'm allowed to talk, and respond, and engage and move around a bit.

I think it's useful, as a famous person, to have as little separation between the perception of you and how you really are - because otherwise I'd be sitting here thinking I'm keeping secrets, and wondering when you're going to find out.
