It's a very organic kind of way that people are discovering it, by word of mouth, which I always think is the best way for things to grow. In terms of the affect it's been having on me, I don't even notice that. It's lovely to be able to talk about a piece of work that you're very proud of, that I think's a complex piece of work and not superficial and has depth to it.

Every Irish person of my generation and earlier, we were raised Catholic and we'd have to learn it in school, we'd to learn the catechism by rote.

My wife can see always how a part affects me personally because she has to live with it.

The best roles you have to fight for. You have to really want to do it and you have to go after it.

It was very much about performances, the whole ensemble thing was just great - everybody working together. Sometimes it didn't feel like a film set. It wasn't technically driven, it was very, very enjoyable

And, for any performer, to be able to go deep into character is fantastic. In film you only get to do that if you're the leading character. But in television you get 18 hours to really test the audience and take them to the edge of how far they will go with this character. I can step over this line and I love that.

I'm pretty adamant to do an American accent because you get it immediately.
