Saw a great "Backstory with the American History Guys” preso on "Birth of A Nation" 100th anniversary over the weekend that was taped on C-Span. Sounds like this film was hugely influential not only as a propaganda piece for Southern White Reconstruction (Alternative) History, but also as a technical masterpiece, at least by the standards of 1915. Looks like you covered it back in 2007 on shows # 151, but might be time to re-visit.http://www.c-span.org/video/?400908-1/birth-nation-100
Just a thought..
