I was talking with some friends this week and conversation turned to headshot trends, audition monologues, and the process of writing a play in the rehearsal room. One of my friends told me about The Anonymous Theatre Company in Portland, Ore. They cast a show -- but no one except the casting director knows who's in the show. Everyone rehearses one-on-one with the director. On the day of the performance the actors enter the theatre in street clothes with the audience, and say their first line from the seats -- after that, they join the cast on stage and the play goes on. It's a one-night only performance. That makes the actor in me terrified. What do you think? What's the most unusual process you've ever worked on as an actor?
