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.

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

I was in the school plays, I did a lot of music. I carried on through university for short films and loads of plays.

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

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.

To me, the difference between New York and London is that things are boring and staid in London. But even the sh-tty diner and bars here are kind of exciting for me. Downtown is funky, West Village is beautiful with the cobbled streets, but I love going uptown because you then you go, F-ck, I'm in New York! You see all the skyscrapers.

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.

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

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

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.

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