The Killing of Sister George

The Killing of Sister George is a 1964 play by Frank Marcus that was adapted as a 1968 film directed by Robert Aldrich.

Although it is strongly implied that George and Childie are lesbians, and towards the end it is suggested that Mercy could be as well, this is never explicitly stated. Marcus intended the play to be a farce, not a serious treatment of lesbianism, but because there was so little material about lesbians it became treated as such.It is usually regarded as a parody of the killing of Grace Archer in The Archers an episode much better known at the time the play was written than it would be in the 21st century. It may also have been inspired by the sacking of actress Ellis Powell from Mrs Dales Diary, and has sometimes been compared with What Ever Happened to Baby Jane?. The death of Martha Longhurst actress Lynne Carrol in the English television serial Coronation Street in 1964 may also have been an inspiration. ........
