 Embassy Pictures included this among a group of sword and sandal/mythological  muscleman epics they put into a U.S. television syndication package called  "The Sons of Hercules." The title was changed to "Fire Monsters Against the  Son of Hercules." The beginning and ending scores were replaced with a theme  song titled "The Sons of Hercules" which was used on all of the films in this  syndication package. Some lines of the English dubbed dialog was replaced  (using another actor) so that Maxus refers to himself as being a "son of  Hercules." After the opening credits, a shot of clouds was inserted and a  narrator would explain that the main character in each of the films was a  "son of Hercules."
