We'll I've enjoyed some of the older WWII films
Sink The Bismark
Battle of Britain
Tora! Tora! Tora!
Battle of the Bulge
Battle of the River Plate
The Longest Day.
To name a few.
And yes I'm under 40, but only by a few years.
I can never watch Battle of the Bulge
without wondering how the Panzer divisions managed to push so deep toward Phoenix or Tucson, or wherever they filmed the European desert scenes.
Someone should make a remastered version and use CGI to at least add snow, and trees, and roads, and some houses.
