The Devils was the Ken Russell film version of the controversial play by John Whiting. The story, based on Aldous Huxley's The Devils of Loudun, concerns controversial 17th century French priest Urbain Grandier, whose radical political and religious notions and profligate sex life earn him many enemies. When a group of nuns appears to have been "bewitched" by Grandier, his rivals feed on the resulting mass hysteria, using this incident as an excuse to have the priest arrested. Refusing to confess to being in league with Satan and to renounce his "heretical" views, Grandier undergoes appalling tortures, and is finally burned at the stake. Vanessa Redgrave co-stars as the head nun. Due to censorship issues in virtually every country in which The Devils has been released, running times vary greatly.
