The World at War was made in the early 70s like me! But nearly 50 years on its probably as definitive a WWII documentary as you'll ever find. The sombre tomes of Olivier as narrator with much rare archive footage particularly Germans' home movies interspersed with interviews from many participants from events then about 25 - 30 years ago at that point.
A lot of the footage contained images of the dead military and all too often civilians something which never fails to shock me. It's not perfect due to the scope of the War they couldn't cover all campaigns, the stuff on india was very cursory. However it is the quality of the interviewees which takes it to another level including Hitler's architect Speer as well as top allied leaders. Amongst the talking heads was one American Army Airforce Captain James Stewart who despite being medically unfit enlisted as a pilot. Great man, great actor rather braver than John Wayne!!!
Just to finish off, the orchestral score by Carl Davies sad poignant and utterly epic.
If you've got about 15 hours to spare this is sobering reminder of what freedoms we take for granted.
