My fear in life, I don't have any kind of specifics like snakes or spiders or anything but I think if I was covered in buttermilk naked running down the street being chased by Gandalf, I'd say, or I don't know, I'm just making it up!

What made me want to be an actor? Ah, I'm not really sure, to be honest. I was one of those little kids who did it around school, and then I got to university and made lots of bad plays and short films, and then midway through that, it suddenly dawned on me that this might be a satisfying way to earn a living, if that was at all feasible.

To me, the difference between New York and London is that things are boring and staid in London.

People say that New Yorkers aren't friendly, but I think they're more friendly than Londoners. Here there is a front-footed nature of Americans. You can go out on a night out and meet 10 random people and stay in touch with them, whereas that's not going to happen in the same way in London.

What is interesting, as well, is how much power homicide detectives have and how much respect. They are kind of rock stars, especially in New York. There are not that many of them.

I don't think I believe in ghosts, per se. But, my nearest experience was when I went on a weekend away and was in a bar in England, years ago, with an ex-girlfriend. I heard this scratching. I was about to go to bed and I was thinking, 'It's an old ghost.' I could hear this noise, but I couldn't work out where it was coming from.

I've got two brothers and two sisters, so there's five of us and we're all very close, which is cool.
