Some actresses are just insane. I've never worked with a nasty actress - they're all absolutely delightful. But completely barking.

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.

When I get into trouble at school I'd like to take an invisibility cloak, drape it over me and sneak out the door. Or I'd like to have a 3 headed-dog because then no one would argue with me.

Realizing that other people have a problem with [homosexuality] was the weirdest thing for me. As a kid it wasn't even something that was mentioned. It was never something that was even explained to me. It was just, "That's Mark and he's gay." Mark was just another friend of my dad's who would talk about his boyfriend instead of his girlfriend. I was 5. I didn't care. It seemed perfectly normal, and still does.

I'm a serial monogamist. I'm not one of those people that can date loads of people at the same time, it's all too complicated.

I sort of try to read the books when they come out impartially and not make up my mind, but the fact is when I was reading the sixth, 'Harry Potter And The Half-Blood Prince', there were bits in there where I was going, 'God, I would love to do that because it's so good'.

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.
