Several B movies and serials had spooky themes in the Weird West genre.
1943's The Haunted Ranch starred Dusty King and erstwhile stuntman Dave Sharpe. Glenn Strange played a henchman, and Tex Terhune brought along his dummy sidekick, Elmer. This mist have been fifty-seven minutes of pure enjoyment!
And, in 1946, Johnny Mack Brown and Raymond Hatton headlined The Haunted Mine with fifty-one minutes of action-packed suspense.
Both of these bottom-of-the-bill second features involved hidden money, gold, loot.
I am looking around for serials with spooky themes. If memory serves, there are a number of those chapter plays with a combination of cowboys on horses, but also thugs in suits who drive cars. Phones as well as telegrams, kerosene lanterns and electric lights, radios in addition to honky-tonks, a real transitional time in America.
If colleagues know of any other sinister westerns in the B movie category, sing out!
