Overview:

Gor /ˈɡɔr/ is the parallel universe Counter-Earth setting for an extended series of novels by John Norman that combine philosophy, erotica, and science fiction. Two films have been made (often considered generic grade-B sci-fi flicks only very loosely based on Norman's books), Gor and Outlaw of Gor (also known as Outlaw); the latter appeared on Mystery Science Theater 3000.
