It's always difficult to put a play on the stage. Actors and crews work hard amid many setbacks that can happen on and behind the stage. If they are lucky, they will survive today's performance with descending curtain and some fulfillment. Then they will have to struggle for another performance tomorrow with today's performance faded into yesterday.
It sounds gloomy, but people in "The Dresser"(1983) stick together and try to go on while believing they are accomplishing something in spite of their mundane reality in and out of theater. At one moment, one character confides to the other about her life spent on theater business: "No, I haven't been happy. Yes, it's been worth it." Norman, played by Tom Courtenay, can say the same thing if asked.
