Space yetis with proton beams want to melt Earth. 1967 Italian sci-fi goes absolutely feral.
A heroic expedition braves snow-whipped precipices and discovers the dreaded humanoids. But wait – these are extraterrestrial yetis who zipped in from outer space to conquer Earth by melting the polar ice caps with high-energy proton fields. Will mankind be global-warmed into surrender?

Trivia, insights & behind the scenes
Antonio Margheriti allegedly directed this, Wild Wild Planet, War of the Planets, and The Snow Devils all in 1966-67 under crushing studio pressure. The films share sets, actors, and a collective disregard for coherence.
This premiered as Italian cinema chased the international sci-fi boom—dubbed into English with American-sounding names slapped on everything, including the Himalayan yeti somehow being extraterrestrial. Globalization was weird in 1967.
