The story is set in southern Italy and recounts the tragedy of Canio, the lead clown in a commedia dell'arte troupe, his wife Nedda, and her lover, Silvio. When Nedda spurns the advances of Tonio, another player in the troupe, he tells Canio about Nedda's betrayal. In a jealous rage Canio murders both Nedda and Silvio during a performance. Although Leoncavallo's opera was originally set in the late 1860s, Zeffirelli's production is updated to the period between World War I and World War II.
The Italiantelevision network RAI had originally wanted to broadcast a live performance of Franco Zeffirelli's 1981 productions of Cavalleria rusticana and Pagliacci from the stage of La Scala. Zeffirelli, however, requested to be allowed to film the productions as if they were movies instead. In part, because both operas starred popular tenor Plácido Domingo, Unitel agreed to help finance the project. Zeffirelli insisted that Canadian soprano Teresa Stratas play Nedda, even though she was not originally cast in the stage production. Over the course of only two days, the director filmed both works at the opera house when it was not in use. He had a wooden platform built over the front seats of the auditorium, where he placed his cameras to film the action onstage. He later did pick-up shots at an Italian film studio.
Soundtrack
For the movie's soundtrack, Georges Prêtre conducted the orchestra of the Teatro alla Scala in the opera house's orchestra pit, while each of the film's performers sang their own parts onstage while the cameras rolled. No audience, however, was present and it was recorded in segments. Plácido Domingo, who had frequently performed the role of Canio onstage since 1966, previously recorded the opera in 1971 under Nello Santi. Philips Records released the film's soundtrack on LP in 1985 and CD in 1990. It received a Grammy Award nomination for Best Opera Recording. In a review of the soundtrack, the MontrealGazette wrote: "Sound effects are included, which lend to the singing a credibility that you do not always feel on recordings." The article also praised Domingo and Statas' singing and noted that the original analog recordings of the movie were digitally remastered prior to the soundtrack's release. Although they were filmed together, the Pagliacci recording was originally released separately from the soundtrack for Cavalleria rusticana.
