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.

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.'

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!

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.

I think you can tell when a New York show isn't shot in the city. It's so iconic and has such a specific energy.

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.
