In Peccato che sia una canaglia (1954), directed by Alessandro Blasetti, Loren starred for the first time with actor Marcello Mastroianni: the film launched one of the most famous and iconic couples of Italian cinema. They teamed up once more in Ieri oggi domani (1963), an episodic film directed by Vittorio De Sica, which won the Oscar for Best Foreign Film in 1965. The famous seduction scene played by the Loren-Mastroianni couple remains iconic. He made eight films with De Sica, almost all with Mastroianni.
