Product Description:
Diving into delirious realms of imagination, this second film of the Godzilla franchise’s 1980s resurgence showcased the towering beast for a new generation of fans. This time, Godzilla’s foe is one of the series’ most wondrously strange kaiju creations: Biollante—a mutant plant genetically engineered from the cells of a rose, a renegade scientist’s dead daughter, and Godzilla itself. With a wild plot encompassing spies, psychic children, and bonkers biotechnology—and some of the coolest special effects in the history of Japanese cinema—Godzilla vs. Biollante stands as a high point in the ever-evolving mythology of the King of the Monsters.
