It's very much an exploration of the human condition and how different people react and respond to their lives. And what they present to the world, in terms of who they are as characters and what is going on behind the mask, in terms of what demons their holding... and how that interacts.

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.

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 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.

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.

I went through the natural process that most actors go through. I brought myself out here, had an audition on a Wednesday; then had a call-back on Thursday, had a call-back on Friday and I had it by Friday afternoon.

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.
