The Actor's Nightmare is a short comic play by Christopher Durang. It involves an accountant named George Spelvin, who is mistaken for an actor's understudy and forced to perform in a play for which he doesn't know any of the lines.
Inspiration
The play was inspired by dreams actors and performers often have in which they are about to go onstage and cannot remember their lines/rehearsal instructions. Durang himself had an actor's nightmare after performing in this play in which he could not remember any lines, could not find his script, and when he did find the script it was gibberish to him. Later the play was the subject of the case See v. Durang where John William See claimed that Durang had infringed his copyright in the play Fear of Acting. The district court summarily dismissed the case on the basis that no reasonable person could find any substantial similarity between the two plays, and the appeals court confirmed this decision.
Plot
A man finds himself inexplicably backstage one day. When he is confronted by the stage manager, Meg, it becomes apparent that he is the understudy for an actor named Edwin and as "Eddie" apparently broke both his legs, the man must perform in his stead. The man is referred to as "George" throughout the play, despite him feeling that it is not his real name and cannot remember attending any rehearsals or being an actor at all. To make matters worse, he is unable to get a straight answer as to what the play is. An actress named Sarah tells him that it is a Noël Coward play and the other actress Ellen tells him that it is a Samuel Beckett play called Checkmate. Literally forced on stage, George attempts to improvise his lines; however, the play inconsistently shifts between scenes from Private Lives, Hamlet, Checkmate, and A Man for All Seasons. When forced to improvise a soliloquy in the Hamlet scene, George tells the audience that he was raised in a Catholic school and was interested in joining a monastery but they told him to wait until he was older. When he was older, however, he lost faith. In the final part of the play, George is alarmed to learn that he is to play the part of Sir Thomas More - and the execution seems a bit too real for his liking. While attempting to convince himself that he is merely in a dream, George ends up theorizing that one can't dream of his own death and therefore he will wake up just before he is beheaded. He accepts the execution, but appears to really be dead during curtain call, much to the cast's confusion.
