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.

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

For better or worse we live in a very exposing [time] where, if you choose to, everyone can see everyone's business. You see what they're having for breakfast, where they are, what they're doing. Whereas I think that classic idea of mystery is very seductive. Not knowing every single thing about a person, what they're thinking, that's very powerful. And it would be a shame if we lost that totally.

A great cologne can really attract a partner. Women particularly respond to smell, and they also have a good sense of memory in terms of men. I think it's very important for a man to wear a good fragrance.

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.

I saw 'Captain America' in 3D. It's cool. I liked the beginning. It's a really good setup.

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.'
