Review by lazarillo

I'm not a big fan of these prehistoric cave-woman movies (i.e. "One Million Years B.C.", "When Dinosaurs Roamed the Earth). Somehow though the Italians managed to take this very dumb late 60's/early 70's "genre" and make it even DUMBER. (They did, however, put in a lot more skin than in the Anglo-American movies--and, after all, no one ever watched these things for the plot, dialogue etc.) This movie probably wouldn't be funny in any language, but the English dubbing here is especially terrible, and they seem to have borrowed the music from "Surfin' Bird" and a Creedence Clearwater Revival song(!). Still, this has a couple points of interest.

Two tribes of prehistoric cave-women are sick of their men always fighting, so they both vow to stop having sex ("ding-dong") with their men until they stop all the wars. If this sounds vaguely familiar, that's because it's the plot of the Aristophanes play "Lysistra". And while this is an exceeding lame version of it, you have to kind of admire the movie for trying to expose the chronic masturbators of that era to the classics.

This movie also features Nadia Cassini, who was probably the third most famous actress in 70's Italian sex comedies after Edwige Fenech and Gloria Guida. Of course, the average person probable doesn't care about that (but then the average person wouldn't be on a IMDb site for a for a goofy low-budget prehistoric cave-women movie called "Quando gli uomoni amarano la clava--etc."). Anyway, if you ARE a fan of Italian exploitation actresses like Edwige Fenech or Gloria Guida, I'd definitely encourage you to check out Nadia Cassini's body--of work. That's all I have to say about this ridiculous movie though.
