The not Hercules films that one of them some publishers advertished as thematic Hercules too. The last is: Ursus, the terror of the Kirguishi , and not "Hercules, prisioner of Evil" as was knowd in english-spoken lands. The action of this movie happended in s. XIV in a kingdom near caucasus.
In the other, Reg ends the play role of action hero: Hercules, Maciste and Ursus. Also, a comic hero. The only thing caracter that he could be played was Conan, but the great readers of conan comics comes in the seventies with collections like "Tha savage sword of conan". I think that the personality of Reg goes better with Hercules than Conan, so this last is the king of the thieves. Better with the trouble life of Arnold. Respects of course to Arnie. Hey man, I want you in your finest condition for your age in this film. And you know as well as me that a fine 6 packs abs is possible.
