Curse of the Undead (1959)
The cinema's first vampire Western! Young women in a small Western town are dying one by one of an unknown malady involving massive blood loss. The Carter family's ranch is being terrorized by ruthless land baron Buffer. And a mysterious black-clad gunfighter with an aversion to sunlight has just arrived in town.
This really is a clever, moody piece, another well-done 1950s Universal-International terror film, featuring good performances, creepy music, and an astonishing climax. (IMDB Marty McKee - twanurit)
