I'm surprised Barbara Tuchman didn't sue the developers of the movie for misappropriation of her title. Though it starts out as she did with Edward VII funeral, and shows the beginning of the war,it is far from her detailed explanations, and goes far beyond August, hopping with giant-steps across the major incidents until the end of the war: the sinking of the Lusitania, the arrival of the Americans, the final German push and then defeat. Great old footage and some strategy maps to help the viewer out but more an anti-German propaganda film than a documentary that might have come from her much acclaimed history. Tuchman certainly thought Germany was at the center of the war, but she showed the deep involvement of the others, as well. The producer-director, Nathan Kroll, was a musician and did other movies with musical themes. He must have self-chosen himself to do this, but inappropriately, I think. For a very good WW I documentary see the 2006 "Gallipoli" (Not the Peter Weir movie) narrated by Sam Neill and Jeremy Irons. It's very good, both filmically and historically.
