| What fun!
If you've read the other reviews of this movie, then you already know most of the storyline. What "The Green Slime" really is is lots of fun. Groovy '60's mod clothes, Japanese monsters and miniature sets, way out dance celebration scene, all great stuff. And if you pay enough attention to the big picture, you can't help but think that this influenced "Alien"; people trapped in space, with killer creatures that can't easily be killed. It's just that "Alien" had a better budget and better writers.

I was lucky enough to see this on the big screen, being as that there is only one print in the US. But it would be fun to rent it some rainy weekend afternoon, with plenty of popcorn and the kids.

Critic Reviews

Did You Know?


In one of the most schizophrenic double features ever cobbled together, this film was doubled billed at a Long Beach, California drive-in with the romantic drama The Only Game in Town (1970). Other than their both having been box office bombs, the two films had nothing but sprocket holes in common.


General Jonathan B. Thompson: Well, this confirms my first guess. The only answer is to blast that thing out of the sky.
Technician: We'll never make it, chief, it's coming too fast.
General Jonathan B. Thompson: We'll just have to move faster.


Captain Martin wears a helmet that covers both of his ears. When he answers the phone, he holds the handset up to his cheek where he couldn't possibly hear the other party.

Alternate Versions

Although "The Green Slime" was released in the U.S. as a 90 minute version, director Kinji Fukasaku and his editor prepared a much more tightly edited 77 minute version (called "Gamma III: Big Military Space Operation") for release in Japan. This "Japanese" version eliminates the Robert Horton/Richard Jaeckel/Luciana Paluzzi relationship triangle, and is much more "militaristic" in tone. Several scenes are edited differently, additional alternate music cues are used (which are less "sci-fi" sounding than the "Amercian" version), and the rock and roll theme song is omitted entirely (replaced by a military march theme). The ending before the credit roll has additional scenes inserted with Paluzzi and Jaeckel, which change the tone of the ending from optimistic to downbeat.
