Synopsis by Hal Erickson
If you know your Japanese giant-monster flicks, you'll know that Gamera is a huge, mercurial flying turtle. Like Godzilla and Mothra before him, Gamera hasn't always been on the side of the humans, but he's been known to save the earth from time to time by warding off even more ferocious monstrosities. Enough Gamera films had been made by 1980 to allow Gamera, Super Monster to rely extensively upon stock footage from earlier productions. To accommodate these excerpts, the plot contrives to have evil extraterrestrial try to rid the world of Gamera once and for all by unleashing all the monsters he's battled in the past. Mach Fumiake appears in the new "bridging" footage. Originally titled Uchu Daikaijuu Gamera, the film was also released as Super Monster Gamera.
