A couple of weeks ago, I went to see an adaptation of "Our Town," also at the Huntington. It was written by famous playwrite Thornton Wilder in 1938, and directed by David Cromer. It begins with a description given by the Stage Manager, who "breaks the fourth wall" by speaking directly to the audience. I'm not going to summarize it, since it had three acts, I don't have the patience to do so, and I know I would butcher it. Also, Wikipedia does a perfectly good job of this sort of thing. I thoroughly enjoyed it, and I think it might have been the favorite of all the more recent plays I've seen.
