Mistero Buffo, or The Comic Mysteries, is based on research into mediaeval mystery plays; The Accidental Death of an Anarchist concerns the "accidental" (or not) death of an anarchist railwork who "fell" (or was pushed) to his death from a police headquarters window in 1969; Trumpets and Raspberries is "A deeply subversive farce" (The Guardian) in which the boss of Italy's biggest car manufacturer FIAT, is mistaken for a left wing terrorist.
