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 know there's Brooklyn and all the boroughs, but Manhattan specifically is so condensed that the energy is very vibrant. Everywhere you look there is something happening.

I've always been freaked out in deep open water if there's a potential of sharks around.

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!

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

In Britain, you do your job. When you do an American TV show, there is a sense of being one with the crew, and there is a leadership element, which was a learning curve for me because it is very different culturally. In Britain, you just do it, leave and say, 'Thanks.'

What I like about the 'Underworld' thing is that it's a mix of cool genres, as well as creating its own message.
