One of the finest occult chillers of all time, the diabolic action centres around Regan (Linda Blair), a 12-year-old girl who falls inexplicably ill and begins to show signs of demonic possession. When psychiatric treatment fails, her mother Chris (Ellen Burstyn) turns to the church in the form of experienced exorcist Father Merrin (Max Von Sydow) and his doubt-ridden assistant (Jason Miller). Based on the novel by William Peter Blatty, director William Friedkin chillingly fashions a truly disturbing - and controversial - tale of supernatural terror. One of the few horror films to win an Oscar - one for adapted screenplay and one for sound.
