I’d consider this one of several lesser-known treasures that I'll add to my all-time favorites when I finally compile the list—it reminded me a bit of *Finnegan Begin Again*. The film really shines because of its cast, who deliver outstanding performances across the board. It isn’t trying to be preachy like some movies with a point to make, although it does explore themes concerning the history and rights of Native Americans, but that important subject doesn't overshadow the narrative. Gary Farmer is wonderful as an upbeat young Cheyenne man who purchases a pony—or rather, a Buick—and teams up with a Vietnam veteran and activist. They embark on a road trip together, and his character draws strength from traditional practices to help his reservation. There’s conflict and suspense, but humor keeps the tone light. The excellent Graham Greene also has a role in the film. The movie is adapted from David Seals' novel of the same name; he was an activist for Native American rights and a longtime member of AIM. It's hard to find a copy that isn’t expensive—I saw them going for around $40 last time I looked. I have a worn-out version that I transferred myself from VHS to DVD, so the picture quality isn’t great, but it will suffice since I like to watch it every few years, and I believe another viewing is in order.
