The Exorcist opened in 1973 accompanied by much hoo-ha in the press. Scenes of panic, nausea and fainting were recorded at every performance. Movie-goers showed up to witness mass hysteria rather than to enjoy a scary movie. This revival, produced by Bill Kenwright, targets the early 1970s demographic. At press night, the stalls were thronged with pensioners eager to relive a lurid evening from their adolescence.
