A year after making this movie, which translates as World of the Vampires, Alfonso Corona Blake would direct Santo vs. Las Mujeres Vampiro. 

Count Sergio Subotai is a vampire who is seeking to wipe out the descendants of his greatest enemy. I’d like to state for the record that he is played by Guillermo Murray. When I was a nino taking el espanol, anyone named Bill was called Guillermo, which means William. So this vampire is really named Mexican Bill Murray.

Another fact that this movie taught me is that instead of a stake through the heart, sunlight, garlic or a cross, music is the best weapon to use against a Mexican vampire. I take that back — stakes are also used.

That said, there are some attractive female vampires and an organ made of human bones and skulls, so this movie isn’t all bad.
