大怪獣ガメラ

A nuclear explosion in the far north unleashes Gammera, the legendary flying turtle, from his long sleep under the ice. In his search for energy, Gammera wreaks havoc over the entire world and it's up to scientists, assisted by a young boy (Yoshiro Uchida) with a strange sympathetic link to the monster, to put a stop to Gammera's rampage. Stars Albert Dekker, Brian Donlevy and Diane Findlay. With Eiji Funakoshi and Harumi Kiritachi. This is the English language version of Daikaiju Gamera (also available here at Rare Movie Collector). In Widescreen format.

Albert Dekker would later die under mysterious circumstances. On May 5th, 1968, he was found bound and gagged, laying in his bathtub with obscene writing in red lipstick all over his body. Detectives later determined he apparently died, by accident, from self-inflicted auto-erotic asphyxiation.

Comes from an excellent 35mm upgraded print.
