A long time ago, probably 30 years, I saw a movie which I enjoyed but have not seen since. It may have been a TV movie. It wasn't Oscar worthy but it was unusual. Most movies are just the same basic tales; the heist, the quest, the love story, fighting an oppressive regime etc. This was different, it was a strange blend of western/buddy movie/horror/supernatural.
These are the scant details I can remember:
Two guys are travelling home, on horseback, after the American Civil War (I think) and rescue a blonde woman from some kind of grim situation. They're in a mountainous area. The woman is mute, possibly from trauma... possibly not; so they decide to take her along with them. Strange things start to happen and I think both men ultimately die. At the end of the film the woman turns into an eagle (yeah really). It turns out she's some sort of ancient spirit beguiling and ultimately preying upon unwary travellers who stray into her domain.
Like I say it's not a great movie but it's refreshingly different enough from most other movies to be an unexpected pleasure.
I can't find it on IMDb because I can't remember any of the actors but the two males leads made an impression. They did a very good "buddy" act so you were rooting for them to escape/survive.
