In 1973, Ferzetti appeared in the TV movie, "Divorce His, Divorce Hers", under Waris Hussein, and "", a British-Italian produced picture directed by Ennio De Concini. Ferzetti played the role of Field Marshal Wilhelm Keitel opposite Alec Guinness (Adolf Hitler), Simon Ward, Adolfo Celi, and Diane Cilento. The following year of 1974, he again appeared in a World War II picture, this time the controversial arthouse classic about the Holocaust, "The Night Porter", working under director Liliana Cavani. He starred alongside Dirk Bogarde and Charlotte Rampling and played Hans, a psychiatrist, one of his most notable roles. The film depicts the political continuity between wartime Nazism and post-war Europe, and the psychological continuity of characters locked into compulsive repetition of the past. Given the film's dark and disturbing themes, and a somewhat ambiguous moral clarification at the end, "The Night Porter" has tended to divide audiences and was accused of mere sensationalism. Film critic Roger Ebert said, "as nasty as it is lubricious, a despicable attempt to titillate us by exploiting memories of persecution and suffering."
