Two escaped convicts are found hiding in a rocketship built by a renegade inventor, who forces them to become the crew for a trip to the Moon. Also on board, as inadvertent stowaways, are his assistant and his secretary; and none of them are aware that the inventor is actually a Lunarian explorer sent to Earth by the dying Lunar civilization and the only remaining male member of that civilization.
Former moon inhabitant Michael Whelan shanghais two escaped cons Tommy Cook & Gary Clarke to help him fly a rocket back to his home. As they are about to set off, they pick up a couple of stowaways in Richard Travis and his fianceé Cathy Downs and so all five make it to the lunar surface. Here they encounter lumbering camouflaged rock men, giant spiders with colourful papier-mâché masks (they might be their actual faces?) and a race of beautiful, blue, women who are facing an existential issue of their own - they are running out of food etc. Watch out for two wonderfully hammy contributions from Nina Bara and KT Stevens. It's a colourful sci-fi romp, but the script is awful and the performances as wooden as the model the rocket ship is made of. I'd give it a miss...
