In 1881 Algeria two men, Hector Servadac (Cesare Danova) and Michael Denning (Sean McClory) are about to fight a duel over a woman when the earth shakes in a great cataclysm that they manage to survive. After a time they realize that a comet grazed the earth, as it has time and again in the past, and taken a bit of the planet into space with it, along with a chunk from the prehistoric past. When Servadac and Denning realize what has happened to them, they don't seem all that upset, a problem with both the screenplay and the acting. Most of the movie consists of stock footage of One Million B.C. with Danova [Honeymoon with a Stranger] and Clory [Them] cleverly inserted into the action. Again we have two warring tribes, two women (Joan Staley, Danielle De Metz), and the big lizard cornering some natives in a big cavern in a hill and gulping down and chewing one of the luckless warriors. Three clips from Rodan are also used to fill in for pterodactyls, as well as what appears to be a prop spider from Bernds' World Without End. Joan Staley is a Ruta Lee lookalike. The premise of the film is good, taken from Jules Verne's novel "Hector Servadac" aka "Career of a Comet," although that did not include prehistoric monsters.
Verdict: The producers wrote the book on "How to Make One Movie Out of Another." **.
