Everest (1970)

In 1921, mountaineer George Mallory is picked by Arthur Hinks of the Royal Geographic Society to scale the previously unconquerable Mount Everest. Following World War I, the fading British empire is desperate for a victory, but for Mallory and his rival, the eccentric Aussie George Finch, the challenge has nothing to do with patriotism, instead it is a singular test of self.
