Sixty years ago, Claudia Cardinale delivered what arguably ranks among the greatest back-to-back performances in movie history when she starred in two masterpieces of Italian cinema, Federico Fellini’s and Luchino Visconti’s The Leopard. The films premiered within months of each other in 1963, with Fellini winning an Academy Award for best foreign-language film and Visconti winning the Palme d’Or. But perhaps even more impressive is that Cardinale, who was just 25 at the time, shot both films concurrently, toggling not just between two sets but between two auteurs and their entirely different visions for her.

In 8½, Cardinale played an angelic muse to a spiritually and creatively broken-down movie director (Marcello Mastroianni) in a film that articulated the search for meaning in a postwar world; in The Leopard, she portrayed the future daughter-in-law of a proud nobleman (Burt Lancaster) in a sweeping tale of Italy’s lost, aristocratic past.
