A Man Called Horse stars Richard Harris as Lord John Morgan, an English peer cast somewhat adrift in the American West. Captured by Sioux Indians, Lord Morgan is at first targeted for quick extinction, but the tribesmen sense that he is worthy of survival. The Englishman passes many of the necessary tests that will permit him to become a member of the tribe, the most grueling of which (and the one used most extensively in the film's advertising) is the Sun Vow Initiation. That's where his lordship is hung from the roof of a huge teepee with hooks through his pectoral muscles. Much of the dialogue is spoken in the Sioux language, though the film's much-vaunted "historical accuracy" is not altogether consistent, as witness the casting of British stage luminary Judith Anderson as Sioux woman Buffalo Cow Head. A Man Called Horse spawned warrant two sequels. Originally rated "GP" in 1970, it has since been re-rated R by the MPAA.
