 "The Mysteries", a modern reworking of the medieval mystery plays, remains faithful to its roots by having the modern actors play the sincere, naïve tradesmen and women as they take part in the original performances.Alternatively, a play might be about the production of a play, and include the performance of all or part of the play, as in "Noises Off", "A Chorus of Disapproval" or "Lilies".Similarly, the musical "Man of La Mancha" presents the story of Don Quixote as an impromptu play staged in prison by "Quixote"'s author, Miguel de Cervantes.
