Uhka avaruudesta

The green slime creatures were played by Japanese children in bulky monster suits.

When the team is on the asteroid, the overhead studio lights are clearly reflected on the helmets.

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.
