Produced by Hammer and written by Nigel Kneale, who created Quatermass, The Witches tells of Gwen Mayfield (Joan Fontaine), a teacher working in Africa who has a breakdown when a curse is put on her by a witch doctor.
She returns to England to teach in a village school but then discovers that the rural community is caught in the grip of a voodoo cult.
Former Hollywood star Fontaine reprises her “frightened lady” turn – first seen in Rebecca – as the cursed schoolmistress. It was to signal her career’s end.
Released overseas as The Devil’s Own.
