Mastroianni enrolled at the University of Rome after World War II. He began an acting career in amateur theatricals sponsored by the university, and in 1948 he joined Italy's leading theatrical troupe. Having made his film debut in 1947, Mastroianni had become a well-known actor in Italy by the mid-1950s. As the star of Le notti bianche (1957; White Nights), he was noticed by the Italian director Federico Fellini who cast him in the leading role of the world-weary journalist in La dolce vita (1960; “The Sweet Life”), the award-winning film that established Mastroianni's international reputation. It was followed by other outstanding pictures—e.g., La notte (1960; The Night), in which Mastroianni portrays a novelist who experiences emotional aridity in his marriage; Divorzio all'italiana (1961; Divorce—Italian Style), a satiric farce about a debonair baron's attempts to free himself from an unwanted wife; and Otto e mezzo (1963; 8 ¹/₂), an Academy Award-winning film also directed by Fellini, with Mastroianni as a creative film director.
