Robert Flaherty was an instinctive filmmaker coupled with a wonderful adventure, trying first to reproduce on the screen his own worldview. In the Canadian Arctic (Nanook of the North), on an island in the austere side of the world, battered by the storms of the Atlantic (Man of Aran) or in the bayous of Louisiana, between magical atmosphere and industrial unrest (Louisiana Story), his films are epics telling the story of the eternal relationship between man and nature. To those who gave him the charge of staging the reality, he replied that "we must sometimes lie in order to reach the truth", thus raising the central question of documentary cinema, art not capture the world, but construction a personal relationship to it. If the "action movie" is first use of the world, when Robert Flaherty is both the inventor and pioneer.
