Warlock is a 1959 American western film directed by Edward Dmytryk and starring Richard Widmark, Henry Fonda, Anthony Quinn and Dorothy Malone. The film is both set and filmed in Utah, including at Dead Horse Point State Park, Arches National Park, Professor Valley in Moab as well as White's Ranch - Milepost 14 Utah Hwy 128, Moab (which was also a set for a number of other western films from the same era). The picture is an adaptation of the novel Warlock by American author Oakley Hall.
Fonda portrays Clay Blaisedell, a freelance marshal in the fictional town of Warlock with implacable methods of dealing with troublemakers. A subplot centers on Blaisedell's club-footed assistant, Tom Morgan, played by Quinn, who has sublimated his relationships and ambition into a warped devotion to Blaisedell, the only person Morgan thinks does not look down on him for his disability.
As in the earlier film Wichita (1955), the conflict of the law with the outlaw runs parallel to the resentment of the town's own leadership.
