I'm not big on awareness about what's going on online but usually if you do too much online stuff then you usually bump into something that hurts.

I think I'm probably quite geeky in a lot of ways. I'm pretty into books, kind of obsessive about that.

I always think that if I'm with somebody, they're better than me. That's why I love them. They're amazing.

In horror films, they sometimes don't show the monster because our imaginations and our own pain is so much greater. Social media is like that. I think it's so great. It doesn't have to show a monster - when you see someone leaving a mean comment, or living a so-called perfect life, you just put all of your pain into that.

My dad says that when I was two or three I used to go out dressed as a different character every day. I remember thinking it was perfectly normal to wear different coloured shoes and carry a pink umbrella. But now I've got a goddaughter of that age; I realise it's not normal at all.

I sort of lived half my life in California, half in England, so I am, I suppose, a little bit American.

The Chinese say that having two homes is the way to madness. I'm not mad, but I definitely wish Hollywood would move to Trafalgar Square. But the life of an actor is a life of movement, isn't it?
