For the episode, see MST3K K00 - The Green Slime.

The Green Slime is a 1968 science-fiction movie directed by Kinji Fukasaku.


When a giant asteroid is detected heading toward Earth, a crew of astronauts disembark from a nearby space station to destroy it. The mission is successful, but the astronauts unknowingly bring a slimy green substance onto the space station that mutates into one-eyed tentacled monsters that feed off electricity.

The creatures reproduce quickly and the crew must stop them before they can spread to Earth.
