A documentary on the life of Eskimos, released in 1922 and directed by Robert J. Flaherty. "Nanook" was the first anthropological documentary film, and is still considered an important historical document. The film covers a year in the life of Nanook, an Inuit Indian, and his family.

Nowadays, we know that some of the scenes were faked slightly. For example, Nanook is depicted living in an igloo and hunting for food, but in real life, Nanook lived in a house and didn't have to hunt very often. However, building an igloo and hunting whales in a kayak certainly were skills that Nanook and the people of his tribe possessed--he was essentially demonstrating for Flaherty's cameras how such things were done.
