I HAVE FOUND IT!!!

I have found the holy grail of movies. It's called Yor, Hunter From the Future and it is one of the greatest movies captured on film. It combines everything you love about action movies into something completely original. A primitive people once living in peace with each other are suddenly devastated by a futuristic group of beings planning to enslave humanity. Yor must search for a way to set his people free. Honestly, greatest movie ever.
