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.'

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.

New York cops are very specific in terms of the way they talk and the way they handle themselves. All these cliches that, as an Englishman, I thought were from a bygone era or were a bit of poetic license with cop shows - the more you hang out with them, the more you realize how real that jargon is.

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.

I find confidence seductive. Confidence, to me, is being happy in your own identity and not being influenced by others. I find that quite seductive because I'm a 50-50 person: in some ways I'm confident, and in some ways I'm quiet, reclusive. [I] like someone who can shake me out of that and approach me.

Don’t never think that you haven’t got anything to learn.

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