Noises Off is the story of a hapless English acting troupe touring a production of a farce called Nothing On. Nothing On must be about something, but it’s hard to figure out what. Audiences can expect lots of doors slamming, sexual dalliances, confusions, and of course, plates of sardines. The encompassing story and the questions about the actors are every bit as deep (and irrelevant) as the questions about the characters they portray. Pam Clifton directs.
