Miljoona vuotta eKr.

As the Shell People are attacked by a giant turtle, Loana calls it "Archelon", the real scientific name for the animal. The name is Greek and means "king turtle".

When the boy tries to steal the meat and has his hand stood on, he cries out and there is a lingering shot of his mouth, showing dental fillings.

Characters and scenes appearing and names used are imaginary, and every reference to names, characters or facts really happened is purely fictional.

The British version runs 100 minutes and features 9 minutes of footage cut from American prints. This includes a scene where Nupondi (Martine Beswick) does a provocative dance; Tumak (John Richardson) tastes from the container of paint in the Shell Tribe's cave; and an extended violent scene of a fight among the ape-men while Tumak and Loana (Raquel Welch) hide, and extended scenes showing Tumak, as he leaves his tribe, shown wandering the valley, and coming across the skeleton of a giant lizard. The widescreen laser disc is the British version (which gives Richardson first billing), while the VHS release is the American version (which gives Welch first billing).
