Joan Crawford (in her last role) plays a scientist who discovers a primitive caveman she dubs "Trog" in a cave only for it to go on a murderous rampage after all attempts to civilize it have failed.

Fairly obscure horror/sci-fi (and rightfully so) has a fairly slow build-up before it introduces the laughable looking Trog (monster mask anyone?) and it gets even more unbearable during the many "teach the monster how to be nice" scenes that have Crawford and the beast bonding over toys, a scarf and a game of rolling the ball.

You'll be fighting off sleep if you watch this bland, pretty laughable and feeble effort.
