The Night Porter () is a 1974 English-language Italian erotic psychological war drama film. Directed and co-written by Liliana Cavani, the film stars Dirk Bogarde and Charlotte Rampling, with Philippe Leroy, Gabriele Ferzetti, and Isa Miranda in supporting roles. Set in Vienna in 1957, the film centers on the sadomasochistic relationship between a former Nazi concentration camp officer (Bogarde) and one of his inmates (Rampling). The film's themes of sexual and sadomasochistic obsession, and its use of Holocaust imagery, have made the film controversial since its initial release, dividing critics over its artistic value, but developing it a strong cult following. In July 2018, it was selected to be screened in the Venice Classics section at the 75th Venice International Film Festival. Plot During World War II, Maximilian Theo Aldorfer, a Nazi SS officer who had posed as a doctor to take sensational photographs in concentration camps, and Lucia, a teenage girl interned in a concentration camp due to her father's Socialist political ties, had an ambiguous sadomasochistic relationship. Max tormented Lucia, but also acted as her protector. In 1957, Lucia, now married to an American orchestra conductor, meets Max again by chance. He is now a night porter at a hotel in Vienna, and a reluctant member of a group of former SS comrades who have been carefully covering up their pasts by destroying documents and eliminating witnesses to their wartime activities. Max has an upcoming mock trial at the hands of the group for his war crimes. The group's leader, Hans Fogler, accuses Max of wanting to live 'hidden away like a church mouse'. Max wishes to remain hidden, but he voices support for the group's activities. Memories of the past punctuate Max and Lucia's present with urgent frequency, suggesting that Lucia survived through her relationship with Max – in one such scene, Lucia sings a Marlene Dietrich song, "Wenn ich mir was wünschen dürfte" ("If I could make a wish"), to the camp guards while wearing pieces of an SS uniform, and Max "rewards" her with the severed head of a male inmate who had been bullying her, a reference to Salome. Because she could testify against him, Lucia's existence is a threat to Max. He goes to see a former Nazi collaborator, Mario, who knows Lucia is still alive; Max murders him to protect his secret. After Lucia's husband leaves town on business, Max and Lucia
