Himalayan Wanderer (1961)

One after another, expedition teams were being attacked in the Himalayas. With the unprecedented boom in snow men, the public began to make a fuss about the fact that the monster that attacked them must be the snow man. Even in Las Vegas, betting began on which country would catch the Snowman. Later, news broke that a Japanese Himalayan expedition had caught the Snowman. The expedition, led by its leader, Dr Kenkichi Domon, lands at the airport, where onlookers and, for some reason, a man named President Otake and his henchmen are waiting to take the Yukio's life, and who appears with the doctor is... a chimpanzee. But this was a trick that Domon used to avoid the panic caused by the boom.

Unfortunately the movie Himalayan Wanderer is not yet available on HBO Max.
