Santo films can be really imaginative. There's one in color "Santo en El tesoro de Drácula" with a time machine tv set where they can watch the past unfolding and it shows a porno version of Dracula--but the production values for that Dracula part of the story are very high end for the late 60s.
Some Mexican films are very memorable like CURSE OF THE DOLL PEOPLE, DOCTOR OF DOOM, HELLISH SPIDERS and THE BRAINIAC (and they often have a wrestling interlude). The dubbing by K Gordon Murrey adds to the enjoyment.
Another one is a weird western RIDER OF THE SKULLS.
I think Ive seen one those the films.
have you ever seen The Robot vs the Aztec Mummy 1959 ? It got the Mystery Science 3000 treatment and deservedly so. This film so unbelievably bad that its actually entertaining .
