In retracing the making of FEDORA, Robert Fischer’s documentary SWAN SONG: THE STORY OF BILLY WILDERʼS FEDORA adds yet another layer of comment and reflection on the film’s very own subject matter: 35 years after playing the romantic leads in FEDORA, Marthe Keller and Michael York look back at working with Billy Wilder – and their careers. Additional testimonies come from acclaimed cinematographer Gerry Fisher, producer Harold Nebenzal, Paul Diamond (son of Wilder’s writing partner I.A.L. Diamond), and German actor Mario Adorf.
