He began his career as a film writer by adapting the lives of historical figures in films such as Pietro Micca or
Don Bosco (1935 film) in the period immediately before the outbreak of
World War II. In the
Post-war period, the advent of the neorealist movement brought him closer to the likes of
Roberto Rossellini and Vittorio De Sica, with whom he collaborated on the screenplays of some of the major works of the period, from
Rome, Open City to Sciuscià. He also worked in parallel as a producer and production manager; in 1949 he founded the film production company Colonna Film in
Rome. Nominated four times for an Academy Award, he was awarded two
David di Donatello and two
Nastro d'Argento. The city of
Gorizia has established the Sergio Amidei Prize, an international award dedicated to him, which honors the best screenwriters on the world film scene. He was romantically linked, for a time, to actress
Maria Michi. He died on April 14, 1981, in Rome. He is buried at the
Campo Verano. ==Selected filmography==
