The Maids (film)

The Maids French Les Bonnes is a 1974 film that was directed by Christopher Miles. It is based on the play of the same title by the French dramatist Jean Genet. The film stars Glenda Jackson as Solange, Susannah York as Claire, Vivien Merchant as Madame, and Mark Burns as Monsieur. Solange and Claire are two housemaids who construct elaborate sadomasochistic rituals when their mistress Madame is away. The focus of their roleplaying is the murder of Madame and they take turns portraying either side of the power divide. The deliberate pace and devotion to detail guarantees that they always fail to actualize their fantasies by ceremoniously killing Madame at the rituals denouement.
