What made me want to be an actor? Ah, I'm not really sure, to be honest. I was one of those little kids who did it around school, and then I got to university and made lots of bad plays and short films, and then midway through that, it suddenly dawned on me that this might be a satisfying way to earn a living, if that was at all feasible.

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.

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

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.

I know I often get a job because of how I look. I hope that I keep the job because of how I act.

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.
