Prehistoric Women (1950)

I suppose this one can be looked upon as a follow-up to the famous One Million BC (1940), though without any dinosaurs - which makes this more accurate. The story concentrates on a small tribe of females from prehistory, perhaps intended as the precursors to the later Amazons. A short flashback near the beginning reveals  how a group of women & children broke off from the males in a tribe about 15 years earlier. In the present, they encounter new males, mostly a handsome guy named Engor. They make him their prisoner, but he ends up helping them.

There aren't any prehistoric monsters - animal threats involve tigers, black panthers and an elephant, though there is some winged creature threat which is glimpsed as merely a typical bird. There's also a semi-legendary 9-foot tall creature called the Wadi or Gwadi, which is just a giant of a man whom everyone fears (with good reason - he's a vicious killer). The women defend themselves using rock-slings, spears and clubs. There's melodramatic narration since the characters do not speak English, only occasional one-word remarks or grunts. Surprisingly, this is in color. Nighttime scenes are too dark. BoG's Score: 4 out of 10

Prehistoric Trivia:
The giant caveman was played by a real giant, an 8-foot tall circus performer from Iceland.
Hammer Films produced a film with the same title in 1967, also called Slave Girls, though some film fans do not regard it as a remake.
