I have seen this superb melodrama broadcast in the afternoon on British TV, a fact which always strikes me as potentially unsound because, as anyone who has seen it all the way through knows, it is scary as hell. At least, at the end.
Recently I had the chance to watch it in the cinema and was disappointed by a poor print and silly giggling from sections of the audience. Buy it on DVD remastered and you will do much better.
A group of nuns occupy a former pleasure palace in the foothills of the Himalayas, meaning to open a school and dispensary. What they don't count on is the emotional impact of the place, its intense atmosphere. This is brilliantly communicated by the most intoxicating colour and set designs at Pinewood Studios, together with a clever musical score and excellent pacing. The frequent comic scenes only serve to heighten the sense of pain and horror as the nuns' spiritual and philanthropic mission is compromised and finally jettisoned.
Great entertainment, relish its fantasy and daring, but keep looking over your shoulder (she's behind you!)
