This film started off well enough (apart from the curious scene with the mysterious rider silhouetted in the setting sun on the horizon contrasting with the cabin in full sunlight) but its last 30 minutes or so dragged along when they should have been more exciting. Very few of the Native Americans looked realistic, one exception being Standing Bear, ironically played by Iron Eyes Cody, whose heritage has been queried in other reviews.
Talking of whom, I couldn't work out the significance of his flashback halfway through the film, when a young Running Wolf visits Standing Bear's cabin and ominously eyes his young daughter (or wife?) who looks nothing like a Native American. Was she to become the mother of Beth, who was later adopted by the Colters? Enigmatic scenes like this make me wish for the IMDB Message boards (discussion forum) of a decade ago where I might have been enlightened.
The version I saw was the full 104-minute version. Perhaps the 60-minute UK cut was less puzzling.
Great cinematography, and it's always good to see Ben Johnson and Jack Elam.
