Nanook_of_the_North Nanook of the North (1922) is a silent documentary film by Robert J. Flaherty. In the tradition of what would later be called salvage ethnography, Flaherty captured the struggles of the Inuk Nanook and his family in the Canadian arctic. The film is considered the first feature-length documentary, though Flaherty has been criticized for staging several sequences and thereby distorting the reality of his subjects' lives.
