Joan of Lorraine is a 1946 play-within-a-play by Maxwell Anderson. It is about an acting company who stages a dramatization of the story of Joan of Arc and the effect that the story has on them. As in the musical Man of La Mancha, most of the actors in the drama play two or more roles. Ingrid Bergman was the star of the original production, playing both Joan and Mary Grey, the fictional star actress who portrays her. As the play begins, Mary Grey and the fictional director of the play-within-a-play, Jimmy Masters, are in conflict over how Joan is to be played. The conflict is resolved during the course of the play.
