Ken Russell’s 1975 adaptation of The Who’s rock opera cast Roger Daltrey as the deaf, dumb and blind boy who finds enlightenment, but downplayed the mysticism in favour of addled Freudian guff. It’s a real mish-mash, with some truly embarrassing moments (Paul Nicholas, for one), but is redeemed by the performances of Ann-Margret and Oliver Reed, interesting cameos from Elton John and Tina Turner, and a stylish sense of design.
