 Peter and his girlfriend Diana are at the center of a lot of the show's drama, the entire cast has remained intact since the show began last year off-Broadway at the nonprofit theater Playwrights Horizons. You know, off-Broadway, it felt very, you know, fake it till you make it. You have to construct intimacy. You have to construct chemistry. I always say that on Broadway, if you had seen it off-Broadway, I think you're going to see a much tighter-knit group.
