You don't get a chance to sit back and relax because this is the point where we're tweaking things to see what works and what doesn't work; so the level of concentration is very focused. But who wouldn't be happy with this? It's a great opportunity and a really great piece of writing. I'm just really very fortunate.

It's like a Master Class in Acting for three hours. I go to work and I learn so much and do so much. I'm privileged. I'm privileged to be on stage with them. That's all I can say. They're extremely generous. There are no egos in the room at all.

For me, it's about having a full life wherever I come to set my hat for a while; so I like to be in a place that offers me a base that's rich and full of people. New York certainly has that at the moment.

I don't want to denounce musicals because they certainly have a message they want to communicate. But with straight plays, there is a focus on what's going on between people and relationships. I think so much is happening in the world at the moment, so many changes politically and culturally, writers are writing about that.

I guess home is where the heart is, as they say. I've moved around the stage a lot - but I had intended on moving to New York anyway so I could live closer to Ireland and to Europe. That's where my sensibility is. This has just facilitated that process.

People want to relate to that. That's a healthy place to be. Even movies do this: War movies or light-hearted comedies, they all have their different time. And this is the time, fortunately, for straight plays... Are you going to come see it?

Honestly, I'd love to think I was in a position where I had that decision. But last year I worked on a movie in Bulgaria, now I'm in New York or LA. It really sounds jet-setting when you say it, but there's lots of down-time where you wonder what you're doing or you wonder about life.
