The actress shot to global fame following spectacular collaborations with legendary director Michelangelo Antonioni in the late 1950s and early 1960s. Vitti starred in "L’Avventura" as a detached and cool protagonist drifting into a relationship with the lover of her missing girlfriend. She went on to star in "La Notte" with Jeanne Moreau and Marcello Mastroianni and "L’Eclisse" with Alain Delon. Each film is considered a classic in its own right.

After working with Antonioni, Vitti changed focus and began making comedies, working with director Mario Monicelli on a number of films.

She went on to star with Marcello Mastroianni in Ettore Scola’s rom-com "The Pizza Triangle," made multiple films with actor and director Alberto Sordi, and played a key part in Luis Bunuel’s "The Phantom Of Liberty." She made two films with Claudia Cardinale in the mid '70s.

Vitti’s first English-language film was the 1966 pic "Modesty Blaise" by Joseph Losey and her second was the 1979 movie "An Almost Perfect Affair" with Keith Carradine.

Her last features were 1990 movie "Secret Scandal" with Elliott Gould, which she also directed, and 1992 Italian TV movie "Ma Tu Mi Vuoi Bene?" The actress retreated from acting soon after given the onset of Alzheimer's.

Over her career, the heralded actress starred opposite actors including Mastroianni, Delon, Richard Harris, Terence Stamp, Michael Caine, Tony Curtis and Dirk Bogarde.

In 2000, Vitti married Italian pianist and composer Roberto Russo, with whom she had been in a relationship since 1973.
