A Man Called Horse (1970)

It was 1825 and John Morgan (Richard Harris) was a bored English lord.  Being a noble with a military commission and inherited wealth wasn't for him.  No, he had resigned his commission and left England.  In lieu of wealth and status, he was shooting "prairie chickens" in the wilds of North America with toothless bumpkins who served as his guides.  Even this had become tedious.  No sooner had he declared his intent to return to St. Louis than a band of Sioux warriors fell upon his camp.  The chief, Yellow Hand (Manu Tupou), took his as a slave.  He described him as no different from a horse, and thus he was thereafter called Shunkawakan, which means horse.

Morgan was ill-treated by the tribe, and his every attempt at escape was easily thwarted.  Soon he discovered an ally among the Sioux; Batise (Jean Gascon), another slave who was fluent in English, French, and Sioux.  From Batise, he learned how to survive.  From his own grit, he learned how to thrive.  In time, he was embraced by the tribe, rising to a valued member.  He was initiated by the Vow to the Sun and married Yellow Hand's sister, Running Deer (Corinna Tsopei).  So satisfying had his life become, all thoughts of escape vanished.

Here is a movie that long predates Dances with Wolves, another movie where a white man adopts Sioux ways.  Historically, there are many examples of whites being captured - mostly as children - by various tribes and then being raised among them.  A contemporary movie, Little Big Man (1970), saw comical take on the white man among the Cheyenne.  The big claim to fame is that Sioux participated, offering details on the culture, practices, and rituals.

Why in the world did Joe (Dub Taylor), Morgan's guide, take him so far from civilization to shoot nothing special?  Joe and his cohorts proved to be useless, clearly unsuited to wandering the frontier. It is only a couple of years since the Arikara War (1823), the start of which was shown in The Revenant (2015).  These guys really are reckless, but how else are we going to explain an Englishman captured by Sioux? Richard Harris reprised the role in two sequels.

Iron Eyes Cody, best remembered as the Indian who wept about pollution, has a role as the medicine man.  He made a career of playing Native Americans, claiming such ancestry, despite being of Italian heritage.

Just okay.
