One of the most fearsome of the Japanese monsters to hit the screen in the early 60's makes his debut in sci-fi thriller. As tensions between America and the Soviet Union rise to a fever pitch, U.S. troops shoot down a Russian bomber which is flying low in an Arctoc region. The bomber crashes, and its payload of hydrogen bombs explode upon impact. The blast releases and awakens Gamera, a gigantic fire-breathing turtle which had been frozen under the ice since prehistoric times. The newly revived monster makes his way to Tokyo, Japan, where he begins to lay waste to the city. As emminent scientist Dr. Hidaka (Eiji Funakoshi) searches for a way to defeat the monster, a young boy named Yoshiro (Yoshiro Unchida) develops an unlikely friendship with Gamera. For the film's American release, additional scenes were added featuring U.S. actors Brian Donlevy and Albert Dekker. The spelling of the monster's name was also changed; he's Gammera with two M's in this movie, but just Gamera in the sequels which followed.
