The first half of this film is a retelling of the two previous films in the trilogy, The Aztec Mummy (1957) and The Curse of the Aztec Mummy (1957), using an ample amount of stock footage from both films.
At one point in the film, a character causes the Aztec Mummy to retreat by showing him a cross. This presumes that an Aztec mummy who has been entombed for centuries knows the significance of a cross.
This film was mocked in Season 1 of the original run of the TV series Mystery Science Theatre 3000 (1989).
The University of California, Los Angeles (UCLA) is mentioned by a scientist in the film as the "University of Los Angeles."
