The Pizza Triangle is a freewheeling satire of Italian mores, hilarious despite its outwardly morbid plotline. The murder of flower girl Monica Vitti triggers a long flashback involving Vitti, middle-aged Communist bricklayer Marcello Mastrioanni, and young pizza chef Giancarlo Giannini. The married Mastrioanni falls in love with Vitti, but Giannini gets in the way. A fight results, after which the girl is hospitalized. Declaring a truce, the three lovers move in together, allowing Vitti tie to decide whom she loves best. The subsequent discord nearly results in the girl's suicide; she moves out and takes up with butcher Hercules Cortes, but returns to Gianinni when he attempts suicide. The now unemployed and unmarried Mastrioanni shows up, and when Vitti refuses again to commit herself to any one man, another fight results--this time ending in Vitti's death. Also released as A Drama of Jealousy and Jealousy Italian Style, The Pizza Triangle was originally shown in Italy as Dramma della Gelosia--Tutti i Particolari in Cronaca.
