The opening credits for The Green Slime offer good insight into the two biggest differences between the often laborious 96 minute American release version and the comparably brisk 77 minute Japanese cut – the music and the editing. The American version features the Charles Fox title theme we’re all familiar with, while the Japanese is scored with a brassy cue from Toei composer Toshiaki Tsushima’s score.
As for the editing, both title sequences use the same footage, but they cut to entirely different scenes. The Japanese cuts directly the a UNSC office, where Commander Rankin (Robert Horton) has been called to deal with an asteroid crisis, while the American credits cut to a pointless scene of Rankin’s commanding officer confronting some of his peers and walking to his office.
