Just found this , starts out with WWI at the start and focused on people who later become famous in WWII.
So they have a young hitler, churchhill, patton, mac arthur, stalin.
They show them and what they did during WWI period.
It is dramatized with actors.
I just got part 1 and 2 have not watched yet. 6 parts total , may be 90 min each.
I think it goes from WWI thru WWII.
I like WWII stuff so will give it a go.
