I just got asked by another journalist 'Are you a feminist?' and I was just like... Is there a strange thing at the moment where you have to come out as a feminist? I've been asked if I'm a feminist so many times recently, and I'm just like 'Yes, yes, for God's sake, yes! Is there something that I give off that says I'm not?'

I'll miss some of the opportunities that playing Harry [Potter] brought me.

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 was worried on a personal level because I wanted to be slightly taller than I am, ideally. But I've now accepted it. Basically, I came to the conclusion a while ago that you can either be really bitter about it or you can make loads of funny jokes.

Dane DeHaan, certainly, is kind of the best friend I've made through acting, in terms of another actor. He's fantastic.

I think that the process of making a film is an underrated factor in how that film turns out.

Go boldly and honestly through the world. Learn to love the fact that there is nobody else quite like you.
