D'Amato and scriptwriter José Maria Sanchez, who had already worked on the first Ator film, prepared a prehistoric film in the vein of the successful Academy Award-winning French film Quest for Fire (1981). The working title was Adamo ed Eva. According to D'Amato, when everything was ready for the shoot and rehearsals had already begun, Miles O'Keeffe backed out for religious and moral reasons. Mark Gregory played the lead role in Adamo ed Eva. O'Keeffe starred in Ator 2 instead. D'Amato commented that "Ator 2 was made in great haste and almost without a script", and includes footage from the first Ator film in the form of flashbacks. D'Amato said they made it "to take advantage of a contract we had with Miles O'Keefe". Release Italy According to Kinnard & Crnkovich, the film was released in Italy on December 16, 1982, while Michele Giordano states that filming only began in early 1983 and both Michele Giordano and Roberto Poppi maintain that the film was never theatrically released in Italy. On VHS, it was released by Eureka Video as Ator l'invincibile, which is the cinematic title of the first part.
