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.

New York cops are very specific in terms of the way they talk and the way they handle themselves.

New York police force seems like unlike any other in America and even the world. There's a very specific culture dynamic, a specific chemistry. There's almost a specific set of rules because of the city and the size of it.

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

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.

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.
