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.
Everything's Cool (film) Everything's Cool is a 2007 documentary film that examines the divide between scientists and the general populace on the topic of global warming. Director Dan Gold said of the motivation for the film that "I'm optimistic that finally the message that this is real, that human beings are the cause of the most recent warming trend, and that it's an important issue, that message is actually reaching America. On the other hand ... if that message was fully understood, we would be moving a lot faster to slow this down and to reverse this course."
