A spaceship filled with stuffy astronauts crash lands on a jungle planet. They encounter giant lizards and spiders and a race of primitives. Gravel voiced Wendell Corey stars as the gruff captain, John Agar is the crusty doctor and Stuart Margolin is the comic relief. In the eye rolling finale, one man and one woman are left on the planet, which the astronauts christen “Earth”. It’s pretty dull and the effects are thoroughly mediocre, but Margolin’s karate lesson is good for a chuckle.
