Born in Italy, Alida Valli was a well-known actress in her homeland before coming to the U.S. She gave a riveting performance as the manipulative and passionate murder defendant in Alfred Hitcock’s The Paradine Case (1947), and portrayed a mysterious Czech woman hunted by the Russians in the post-war classic set in Berlin, The Third Man (1949). She returned to Europe in the early ‘50’s and continued her acting career, appearing in her final film in 2002.
