The Headless Rider(1957)

Original title: El jinete sin cabeza

A mute phantom hero takes on skull-masked killers, a disembodied living hand and a corpse that won't stay in its grave. This is the first in a trilogy of horror/western hybrids that also includes the films La marca de Satanás ("The Mark of Satan") and La cabeza de Pancho Villa ("The Head of Pancho Villa").
