A space probe is infiltrated by alien beings and then crashes on a remote Pacific atoll. A group planning to build a resort hotel land on the island and discover it to be inhabited by giant mutant monsters created by the aliens in an attempt to conquer the world.


For your Decades of Horror 1970s Grue-Crew, the operative word for Space Amoeba is “fun!” Chad, Bill, and Doc are big Kaiju fans, while in comparison, Jeff is relatively inexperienced. Even so, their comments are pretty universal regarding Yog: Monster from Space. Chad says the sillier the better and if you want silly, you got it with Space Amoeba. According to Bill, it’s not great, but how can you not have fun with big rubber monsters slapping each other. Doc wonders aloud if it is good and then answers his own question: technically no, but it sure is a lot of fun. Jeff agrees with the rest of the crew on how fun Space Amoeba is and he manages to learn something as well as Bill schools him on the difference between amphibians and reptiles.

As long as you’re not looking for a Godzilla (1954) type kaiju film and are out for some good clean fun, your 70s Grue-Crew recommends Space Amoeba. At the time of this writing, the film is available for streaming on Amazon Prime.
