Ugo and Chino-without developing any of them satisfactorily", and criticized Mario Adorf's portrayal of Rocco as "often verg[ing] on caricature". Legacy Di Leo's later film Blood and Diamonds (1978) is considered by Curti to be a "reversal" of Caliber 9, with the relationships in the film being contrary to each other. Blood and Diamonds''' working title was Roma calibro 9, and Barbara Bouchet plays similar roles in both films. Moschin would later play a gangster character, Don Fanucci, in The Godfather Part II (1974). The film was referenced in Kobe Bryant's Nike Italia advertisement campaign short entitled "Milano Kalibro Kobe", and featured Italy international footballers Giampaolo Pazzini, Gennaro Gattuso, Alberto Aquilani, Claudio Marchisio and Marco Materazzi, Dutch international footballer Wesley Sneijder and Italian NBA star Marco Belinelli in parodies of the original characters. The commercial was directed by Enzo G. Castellari, who, like Di Leo, was a prominent director of poliziottesco films. Sequel A direct sequel film, Calibro 9,'' was produced in 2020. It is directed by Toni D'Angelo and produced by Gianluca Curti, whose father Ermanno was a co-producer of the first film. The cast stars Marco Bocci as Fernando Piazza, the son of Moschin's character, with Barbara Bouchet reprising her role as Nelly Bordon. It also features Michele Placido, Alessio Boni, and Kseniya Rappoport.
