Bizarre nightmares plague Regan MacNeil (Linda Blair) four years after her possession and exorcism. Has the demon returned? And if so, can the combined faith and knowledge of a Vatican investigator (Richard Burton) and a research specialist (Louise Fletcher) free her from its grasp?
Employing production design and special effects that are dizzily exhilarating and a supporting cast (Max von Sydow, Paul Henreid, James Earl Jones) of compelling distinction, director John Boorman draws us into the tangible experience of evil. We fly with the demon, feel the African landscape vibrate and get engulfed in the terror of swarming locusts as Exorcist II: The Heretic weaves its fascinating, frightful spell.
