Hitler's War: What the Historians Neglect to Mention. An English translation of "Hitlers Krieg? Was Guido Knopp Verschweigt" by Alphart Geyer (Germany 2009). This is a 96 minute long "Made in Germany" underground documentary film. It's the first documentary ever to unabashedly explain from the German perspective, how World War II really began, and the many efforts that were made by Hitler to avoid it, and to establish a lasting, viable and mutually acceptable peace, but how he was ultimately left with no choice but to invade Poland. It documents many facts that have been deliberately left out of the "official narrative" as presented by the victorious Allies, which we have all been taught since 1945, and which Germans especially have been constantly reminded of since the war ended; with the blame entirely upon Germany's shoulders. Many of the claims of the Allies that have been widely accepted as fact are refuted here as patently untrue, distorted, or ignored completely.

I found it a very interesting documentary and it is specifically what the Historians neglect to mention, it doesn't talk about the camps of Nazi brutality so keep that in mind.
