Creature Feature: FRANKENSTEIN CONQUERS THE WORLD (1966) NICK ADAMS

One of my favorite Creature Features as a kid was FRANKENSTEIN CONQUERS THE WORLD starring Nick Adams.
Frankenstein vs. Baragon (Japanese: フランケンシュタイン対地底怪獣バラゴン, Hepburn: Furankenshutain tai Chitei Kaijū Baragon; lit. 'Frankenstein vs. Subterranean Monster Baragon') is a 1965 kaiju film directed by Ishirō Honda, with special effects by Eiji Tsuburaya. The film stars Nick Adams, Kumi Mizuno and Tadao Takashima, with Koji Furuhata as Frankenstein and Haruo Nakajima as Baragon. An international co-production of Japan and the United States, it was the first collaboration between Toho and Henry G. Saperstein. In the film, scientists investigate the origins of a mysterious monster boy Frankenstein and his resistance to radiation that makes him grow to monstrous size, while another monster Baragon ravages the countryside.
Frankenstein vs. Baragon was theatrically released in Japan on August 8, 1965, followed by a theatrical release in the United States on July 8, 1966 by American International Pictures as Frankenstein Conquers the World. The film was followed by The War of the Gargantuas, released on July 31, 1966.
The film was released in Japan on August 8, 1965, two days after the 20th anniversary of the Hiroshima bombing. The film grossed ¥93 million during its Japanese theatrical run. The film was released theatrically in the United States as Frankenstein Conquers the World on July 8, 1966 by American International Pictures. This version was dubbed in English by Titan Productions[1] and restored Adams' original English dialogue.
The following year, Toho released a sequel titled The War of the Gargantuas, also co-produced with UPA. In the film, pieces of Frankenstein's cells mutate into two giant humanoid monsters: Sanda (the Brown Gargantua) and Gaira (the Green Gargantua). The former is a benevolent and peace-loving creature, while the latter is murderous and savage. Apart from a reference to a severed hand, UPA obscured all references to Frankenstein in the American version and the names of the monsters were changed to the Brown Gargantua and the Green Gargantua.
