Richard Harris gets hung by hooks through his chest in the infamous Sun Vow Initiation sequence, much imitated in video nasties, but otherwise this 1970s hippie-era version of Dances With Wolves is unmemorable.
Harris' masochist excesses as a British nobleman abducted by the Sioux and enduring trials before being accepted as an Injun hardly sit well with such "realistic" touches as casting Dame Judith Anderson as a Sioux matriarch.
Straining for significance at every moment, this is one of a wave of late '60s/early '70s Westerns that represent Hollywood's idea of the counterculture in love beads, feathers and picturesque gore.
Apparently not having that bad a time of it, Harris followed up with three more oddly sado-masochistic Westerns, including Man in the Wilderness (1971), The Deadly Trackers (1973) and The Return of a Man Called Horse (1976).
