In preparation for sending a manned rocket into space, American scientists Dr. Quent Brady and Dan Morgan are put in charge of a program that sends various animals and insects into space to test their survival rates. After one of their rockets carrying wasps malfunctions and goes off course, a computer calculates that the rocket is likely to land somewhere off the coast of Africa. Some time later, in a remote part of Africa, Dr. Lorentz and his daughter Lorna perform an autopsy on a native and determine that he died of paralysis of the nerve centers caused by an injection of a massive amount of venom.

Jock Ewing meets Albert Schweitzer and some big old Wasps
15 April 2006 | by bkoganbingSee all my reviews

Before Jim Davis got his last and career part as Jock Ewing in Dallas, he had one tortured path to Hollywood success. He had a much publicized debut as Bette Davis's leading man in Winter Meeting which was one of her worst films. His portrayal of a war hero about to enter the priesthood met with a ton of critical guffaws. Still Davis persisted and took any kind of work. The Monster from Green Hell qualifies as any kind of work.

A wasp is sent up in space to see the effects. Unfortunately on re-entry the space capsule crashes in the region of West Africa and the wasp has grown to the size of a Panzer tank. To top it all off the geniuses sending up the rocket sent up a pregnant queen so we've got all kinds of those Panzer wasps running around Africa.

Jim Davis is sent to clean up the mess and runs into a medical missionary played by Vladimir Sokoloff. Albert Schweitzer was very much alive at the time and running his mission in West Africa. No one in 1958 mistook who Sokoloff was portraying. The wasps set up a colony in the shadow of a volcano. You can figure out the rest.

This is typical Fifties science fiction when all kinds of radiation was the explanation for these creatures. In this case it was the radiation from cosmic rays, presumably from the newly discovered Van Allen belt around the earth.

Tepid acting and chintzy special effects make The Monster from Green Hell great cult stuff. One thing though that is timely. An Arab character played by Eduardo Ciannelli joins forces with Davis and one of the natives Joel Fluellen to combat the danger the giant wasps present. Amazing how religious differences can suddenly melt away in time of crisis.
