Does Bill Duke or Robert J. Flaherty have more credits for documentary films?
Robert J. Flaherty Robert Joseph Flaherty, FRGS ( ; February 16, 1884 – July 23, 1951) was an American filmmaker who directed and produced the first commercially successful feature-length documentary film, "Nanook of the North" (1922). The film made his reputation and nothing in his later life fully equaled its success, although he continued the development of this new genre of narrative documentary, e.g. with "Moana" (1926), set in the South Seas, and "Man of Aran" (1934), filmed in Ireland's Aran Islands. He is considered the "father" of both the documentary and the ethnographic film.
