Sister My Sister is a 1994 film starring British actresses Julie Walters, Joely Richardson, and Jodhi May. The film is directed by Nancy Meckler and written by Wendy Kesselman, based on her own play, My Sister in This House. Both the play and the subsequent film deal with societal repression and its victims.
Christine Richardson is the maid of a welltodo widow Julie Walters and her daughter Sophie Thursfield. Her sister, Lea May is hired on the recommendation of Christine. The two sisters become increasingly alienated from their employer, separated by barriers between the classes. With only each other to turn to and Christine experiencing much jealousy as to her sisters interest in anyone else, the relationship becomes sexual, adding to the tension between the sisters and their employer. The tension ultimately leads to paranoia, repressed rage and murder.The Papin case was also the subject of The Maids, a play by Jean Genet written in 1949 that was adapted by Christopher Miles into a 1974 film of the same name. It starred Glenda Jackson and Susannah York as the maids, and Vivien Merchant as their employer. ........
