An interesting ‘compare and contrast’ to yesterday’s MotD. One is a man’s id that is running amok without his conscious knowledge or awareness. Gor, meanwhile, is a space brain that takes over a human male and, in contrast to the normal run of things (wherein the brain would impose an ‘inhuman,’ coldly intellectual persona on his victim), instead gets into the whole ‘sins of the flesh’ and uses his host’s body to really tear it up. Or at least as much as you could in the ’50s, anyway.
This latter idea has been explored in subsequent stories and films, but this is one of the first cinematic manifestations of it. And, of course, the movie inspired the very first gathering of the B-Masters Cabal, way back in the day.
