Time travelers from the future warn Japan that Godzilla will eventually destroy their nation, so they hatch a scheme to rid the world of the King Of The Monsters. They travel to a small island in 1942, during WW2 and make sure Godzilla dies there before becoming a radiated monster.
They let three little creatures out and when the time travelers believe there will be no more Godzilla, their plans become very clear. The little creatures are radiated and become King Ghidorah, who will destroy Japan and stop it from becoming an economic leader.
The plot is very convoluted, but it is fun to watch and I think it look very good on Blu-ray. Ghidorah has always been my favorite Japanese monster and this is a great showcase for him. I can't see any Godzilla fan not wanting to see this, and I picked mine up at Hastings when they had a huge shelf full of them, now they have sold out of every Godzilla film they had, so I guess that proves others enjoy these great little films from the Land of the Rising Sun.
It's out on a double feature with "Godzilla and Mothra Battle For The Earth" which will be reviewed here shortly. Recommended.
