I always say the things you're not supposed to.

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

People are weird. We do live on all levels at the same time and you can be fighting and flirting, and there can be fury and sexual tension. All that stuff can co-exist so it's just a testament to how complex we are. Or maybe it's a testament to how boringly we try and simplify everything.

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.

What you're seeing, certainly on Instagram, is not real, not a reflection of real life, not an interaction.

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?

My dad, in particular, was adamant that I should finish my education. He encouraged me to go to Oxford, for instance, and I rather doubt I'd have gone if he hadn't. I would have gone straight back to L.A. and tried to start my career.
