Imagine "One Million B.C." (1940) with fewer dinosaurs but more pretty girls -- and in color!
Presto! "Prehistoric Women". And of course, tradition demands that none of the characters speak English. (Trivia note: Only two out the six "prehistoric" movies ever made allows the characters to speak English, one of which is the 1967 Hammer production, "Prehistoric Women", ironically enough).
At least this seldom-scene 1950 production provides a narrator to tell us interesting things about evolution that our school text books neglected.
An oversized caveman developes an interest in Mara Lynn and Luarette Luez, the principle females, who provide nice eye-candy for the male viewers. This is a recommended second feature for "Mesa of Lost Women" for obvious reasons. And Allan Nixon stars in both films!
