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.

Usually, if you're buried alive, that's gonna be the last time that happens, isn't it?

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.

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?

I can't say that I know the lexicon as intimately as a lot of people, so I may be unworthy of being called a Trekkie. That would be doing a disservice to the people who really are Trekkies.

In film, the camera can get an array of shots so the audience can see the emotion the character is giving off. Using close-ups on the characters face really helps get the message across. On stage, you cant do that. But the stage has that live feeling that you cant get anywhere else because the audience is right there.

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.
