I need a release from whatever I'm writing.

Hopefully this is going to be a trend, the beginning of a movement to reclaim theater for the artist and not commerce. I think there's a level of fatigue. Artists are tired of having to create work that's then coopted by commercial demands. When you begin souping up the car, the car no longer feels like your own.

If you lead with the anger, it will turn off the audience. And what I want is the audience to engage with the material and to listen and then to ask questions. I think that 'Ruined' was very successful at doing that.

It's much easier to conjure characters strictly from your imagination than to have to think about whether you're representing people in a truthful way.

When you begin a play, you're going to have to spend a lot of time with those characters, so those characters are going to have to be rich enough that you want to take a very long journey with them. That's how I begin thinking about what I want to write about and who I want to write about.

I wanted to tell the story of these women and the war in the Congo and I couldn't find anything about them in the newspapers or in the library, so I felt I had to get on a plane and go to Africa and find the story myself. I felt there was a complete absence in the media of their narrative. It's very different now, but when I went in 2004 that was definitely the case.

When the play is still evolving I try to be at rehearsal as often as possible, and part of that casting process. You find new things when the language is living in different people's mouths.
