David Mamet's funny, haunting "A Life in the Theatre" … is entirely a matter of conversations between two actors—a young one, John …, and an older one, Robert…. They meet when they are rehearsing together for a show, and over the course of the evening we follow the growth of their friendship…. [Collaterally, we follow their careers through] fingernail parodies of various hack scenes from every conceivable kind of hack play the two actors have appeared in…. Mr. Mamet has exposed the character of Robert—a sympathetic exposure, to be sure—and under all the pomposities and nonsense we see the nervous, touchy, tentative, and very lonely older man who must rely on the conventions and the lore of "the boards" to give him some inner dignity and confidence. (pp. 115-16)

Mr. Mamet has written—in gentle ridicule; in jokes, broad and tiny; and in comedy, high and low—a love letter to the theatre. It is quite a feat, and he has pulled it off. (p. 116)
