On January 7, HBO will begin broadcasting director Andre Singer's film "Night Will Fall". It's a documentary about a documentary- one that is as fascinating as it is relevant. The film traces the tortured history of a documentary about the liberation of concentration camps in WWII. The film was authorized by the Allies in the immediate aftermath of the war. A man named Sydney Bernstein was told to chronicle the horrors that the liberators encountered in freeing the survivors of Hitler's genocidal policies. The purpose was clearly to make a propaganda documentary that would prove that the average German citizen had been well aware of what atrocities had been carried out in their name. Bernstein and his crew dutifully carried out their orders, but they were given only a three month period to complete the film. The shocking footage had such an impact that the project went beyond what Bernstein had been ordered to do. He enlisted Alfred Hitchcock to help supervise the editing process. The footage is said to surpass anything seen to date in terms of the sheer inhumanity depicted. Bernstein and Hitchcock ran out of time before the project could be completed and Billy Wilder took over supervision of the project, delivering a shorter film that had less impact than Bernstein's. The entire bizarre affair is chronicled in "Night Will Fall", which includes never-before-seen footage from Bernstein's aborted cut of the film. For more - and to view the trailer- click here.
