Behind the scenes
Though unspecified in the script, Nanook of the North was a 1922 award-winning documentary about Arctic s that claimed to be a depiction of a real person and his family, though the entire film was in fact a staged hoax. The name became synonymous with being prepared for, or thriving in, wintry conditions.
