This film, the second one in the "Aztec Mummy" trilogy, features a superhero that is dressed like a masked professional wrestler. It thus predated the superhero/masked professional wrestler film sub-genre that would become popular in Mexico during the 1960s and 1970s. The Angel of this film seems to be a direct inspiration for the later series of films featuring Santo, all the way down to his nifty little white sports car.
In the English-dubbed version of this film, released in the United States as "The Curse of the Aztec Mummy," Flor was re-named "Flora."
