When Women Had Tails (Italian: Quando le Donne Avevano la Coda) is a 1970 Italian comedy film set in pre-historic times when “women had tails” and were hunted by cavemen.

It stars Giuliano Gemma, Senta Berger, and Lando Buzzanca.

After a fire burns all the vegetation, they set out to find a new place to live.

One day they trap a strange animal, looking very similar to them, only softer and with longer hair.

She, Filli (Senta Berger), is attracted to one of the brothers, Ulli (Giuliano Gemma), and convinces him that a certain kind of playing with each other is far more satisfying than just eating her.
