The area behind and around what you see on stage. â€œBackstageâ€ may include the wings, dressing rooms and other nifty out-of-sight places. Some plays, such as Michael Fraynâ€™s farce, Noises Off, and Ronald Harwoodâ€™s poignant drama, The Dresser, actually portray life backstage. It can be pretty intense.
