The Devils review – Ken Russell’s 1971 possessed-nuns tale is a frenzied aria of confrontation and hysteria

Oliver Reed and Vanessa Redgrave put in the performances of their lives in this film originally banned for obscenity that highlights the violence of power

‘I could never be Satan’s boy. I haven’t the humility.” The speaker is Father Urbain Grandier, the 17th-century French priest accused of witchcraft, stylishly played by Oliver Reed, in Ken Russell’s scabrous 1971 classic; it is now restored and rereleased in its complete form after years of censorship. It comes from an era when movies, playing in high-street cinemas, still had the power to shock, to position that shock in the polite cultural mainstream and to compel serious discussion about whether that shock – or, conversely, a ban – was justified.
