5. The Exorcist II: The Heretic (1977)
Starring Linda Blair, Richard Burton, Louise Fletcher, and James Earl Jones (in a locust suit, but I’ll get to that) and directed by John Boorman, The Exorcist II: The Heretic, is the Highlander II: The Quickening of The Exorcist series, and by that, I mean it’s the movie that most fans of the franchise say, “What second movie?” The story is about a priest, played by Richard Burton, who travels to Africa to find a boy formerly possessed by the demon, Pazuzu. He learns of Pazuzu after Regan from the first movie (played by an all-grown-up Linda Blair) is put under hypnosis with this strange, dream-reading machine, which reveals that Father Marrin from the first film once encountered Pazuzu in Africa. Locusts ensue.
