The vampire women capture and drain the blood of human beings to make themselves beautiful, and just what's so wrong about that you PETA protesters? Sampson vs. the Vampire Women was directed by Mexican filmmaker Alfonso Corona Blake in 1962 under the original title Santo vs. Las Mujeres Vampiro.
The American trailer plays up the vampire ladies, but the real point of the film was to feature Santo (Rodolfo Guzmán Huerta) who is one of the best known Mexican wrestlers of all time (and very much the folk hero). The film was a hit in Mexico and quite a few other films were made over the years which would feature Santo dealing with everything from She-Wolves to the Bermuda Triangle.
