prehistoric women (1950)

aka The Virgin Goddess.
"Strangely enough the swan dive was invented before the swan."
The story of a tribe of prehistoric glamour models, who get the itch and capture some men to satisfy it. But one man eludes them and in his journey discovers fire, something that comes in handy when he rescues the leader of the women from a flying monster. And thus the women realise that their rightful place is in serving men.
