If I was left to my own devices, you would see about ten T-shirts in rotation with maybe a few nice pairs of jeans - but I also like to look good. I like feeling really well put together, I just don't have the aptitude and the knowledge to do that.

I'm never going to be in something as commercially successful as 'Harry Potter' ever again. It's impossible. So that gives me incredible freedom to go off and make the slightly off-the-wall films that I want to make.

Normally I sit there in the films really hating watching myself. Loving watching the films, hating watching myself.

As an artist, you have a path that you're on that evolves with the kinds of stories you want to tell.

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.

I used to joke I was a point-and-click actor. My whole process has been about trusting your instincts and hitting your mark.

I think honesty is the most heroic quality one can aspire to.
