For ages, in my lunch hours, I would just go round and choreograph fight scenes. For fun. So now I'm very good at being thrown around. I bounce, in the words of my friends.

I am a frighteningly thorough person.

Sometimes you can't help but pay attention to what is written about you. You are trying not to because it's generally not constructive, it can be very funny, in which case it's fine to pay attention to it if you're going to laugh about it. But if it's going to get you angry then it's a pretty pointless waste of energy, so I try and be selective about what I take an interest in about myself.

What first attracted me to doing Swiss Army Man was just how mental it was - how insane and wonderful and original the script was.

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

I think one of my favorite things to do is just lock myself up in a small room and listen to music and watch films for a day. Also I just like seeing my friends. We have pizza parties which means I get four friends round, we eat a pizza and we're really lazy and we play PlayStation.

I had to smile when stories emerged questioning whether I was gay. Obviously I knew I wasn't but people were curiously desperate to suggest I was ... when you know a gay guy has a crush on you, it's the most flattering thing.
