Cavemen vs. dinosaurs and robots!!! Well that's something you don't see everyday...unless of course yor reading this review far in the future and maybe even on another planet where cavemen fighting robots is an everyday occurrence. The future sounds pretty awesome.
Yor is a blond-haired, buff cavemen and one day he beats up a dinosaur and saves a sexy chick. She introduces him to her tribe and they ask about his shiny medallion. Suddenly the village is attacked by a gang of apemen who kidnap all the women for a rape party in their cave. Yor hasn't even got to tap that pussy yet so he chases after the apemen. Sensing the party is about to begin Yor kills a giant flying bat creature and uses the corpse as a fucking hang glider (how does that even work?!) and swoops down, kicks some apeman ass, grabs the hottest chick and then floods the cave! I can only guess that the flood killed all of the apemen and the numerous captive women!
Anyway, Yor and his few new friends travel on to solve the mystery of shiny medallion and discover [SPOILERS!!!] that they are actually in Earth's future not the past! Where the fuck did the dinosaurs come from then?! Radiated pigs is my best guess. So there's this evil guy who's trying to keep mankind stupid in order to save us from killing ourselves all over again with nuclear weapons or something. I could be completely wrong. I was pretty confused by this point.
I liked YOR quite a bit. It's dumb as fuck, but just cheesy enough to make it a lot of fun. The theme song alone makes it worth watching. If you like cheesy bad movies then you should check it out.
I've heard rumors that there's a much longer version shown on Italian television back in the 80's. I don't know if this is true or not, but I would love to get a hold of a copy.
