Might have missed it, but Broken Trail.
Wiki
Broken Trail is a 2006 Western miniseries directed by Walter Hill and starring Robert Duvall and Thomas Haden Church.[1] Written by Alan Geoffrion, who also wrote the novel,[2] the story weaves together two historical events—the British buying horses in the American West in the late 19th century and Chinese women being transported from the West Coast to the interior to serve as prostitutes—along with a series of Western vignettes.
Filmed on location in Calgary, Alberta,[3] the miniseries originally aired on American Movie Classics as its first original film. Broken Trail received Emmy Awards for Outstanding Miniseries, Outstanding Lead Actor in a Miniseries or Movie (Robert Duvall), and Outstanding Supporting Actor in a Miniseries (Thomas Haden Church).[4]
