The major qualm that most people have with this movie is that it does not fit the vision of the Gor book series. So what. There are far better reasons why not to watch this movie, like Mulletboy.
Tarl, a nerdy college proffessor, gets transported to the world of Gor where he witnesses the hijacking of the homestone, and its defence by Talana, scantily clad Playboy model (ironically not the worst actor in this movie, actually she was better than most of the others). She tries to convince Tarl (what kind of name is Tarl, who on earth would name their son something so stupid?) Also with them is Mulletboy (guess why I call hiim that). Together they must go and rescue Talana's father and their heartstone.
The fight scenes in this movie were all identical. Swords clashed for about 2 seconds then someone got kneed in the gut. The one thing that can save a sword and sorcery film is good fight scenes and this movie does not deliver. Furthermore the action in this movie is minimal and far in between. Also, the plot is nonsensical and nothing at all is explained. Things are done for no apparent reason and other things that should probably happen don't.
The plot is so laughable. I can't quite convey why it is so corny in words, but take my word for it it isn't worth enduring.
The only saving grace of this movie is the eventual death of mullet boy.
