This film is also known as "Colossus of the Stone Age" but was released to TV here with the moniker under which this is reviewed.
Reg Lewis is Maxxus, a wondering strongman who comes to the aid of a man and saves him from a monster living in a lake. Later he defends the mans Sun worshiping tribe from an attack by a tribe of Moon worshipers.
The Moon tribe kidnap all the women and Maxxus leads a revolt. He succeeds but is himself captured. A young woman who is found on Maxxus tries to help him and she is caught as well. Both are buried up to their necks in the dirt and tortured until an earthquake opens the ground and saves them.
They escape and run into prehistoric monsters before finding their way back to the tribe of the Sun people. Then another war starts as the Moon people attack once more.
This is an action packed 78 minutes with warring tribes, several different monsters as well as the screen debut of Margaret Lee as Moah, the stunning woman who falls for Maxxus. Lee, of course would go on to star in lots and lots of movies, and every time she is on screen it is sheer pleasure for me.
This is one of the best films of this genre as far as I am concerned, and I think every fan should at least see it once.
