Gamera, the Giant Monster (1965)

"Striking down jets, grabbing hold of the Tokyo Tower, flying through the air breathing fire, the giant monster of the century!"

A nuclear explosion in the far north unleashes Gamera, the legendary flying turtle, from his sleep under the ice. In his search for energy, Gamera wreaks havoc over the entire world, and it's up to the scientists, assisted by a young boy with a strange sympathic link to the monster, to put a stop to Gamera's rampage.
