This was the first of eight starring feature film roles Marcello Mastroianni would appear in for Ettore Scola. These films included Un día especial (1977), La terrazza (1980), La noche de Varennes (1982), Permette? Rocco Papaleo (1971), Splendor (1989), Che ora è (1989), and Maccheroni (1985).
Marcello Mastroianni won the Best Actor award at the 1970 Cannes Film Festival. The director Ettore Scola won the Palme d'Or nomination.
"The film, though a winner primarily because of its performances, has the fun air of some of the earlier postwar Italian comedies," remarked Cue magazine, while The New Yorker called it "a genial mutt of a movie - a comic-strip parody of operatic passion."
Originally titled Dramma della gelosia (tutti i particolari in cronaca). This translates awkwardly to "Drama of Jealousy (All the Details in the News)." It was promoted at the Cannes Film Festival as "What a Lovely Day." When that title failed to click, it was renamed "Jealousy, Italian Style," a half-hearted attempt to riff on the previous decade's cycle of comedies like Divorcio a la italiana (1961), Matrimonio a la italiana (1964), Due marines e un generale (1965) and Ghosts, Italian Style (1967). Other names included "Jealousy Drama" and "The Motive Was Jealousy" before Warner Bros. finally settled on its most commonly referred to English title for the U.S. release, "The Pizza Triangle."
