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.

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

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.

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

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.

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

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