Pagliacci is often celebrated as one of the finest examples of verismo, or realist opera. It is even based on a true story: Leoncavallo's father, a judge, once presided over the trial of an actor who, in a fit of jealousy, murdered his wife immediately following a performance. Pagliacci is frequently performed along with Mascagni's one-acter Cavalleria Rusticana. Both works are strongly linked with the name of Franco Zeffirelli, the great stage and film director who has been infusing the operatic repertoire with grace, elegance and poignancy. Both his Emmy Award-winning production of Pagliacci and his Cavalleria feature international star tenor Placido Domingo.
