I have to add 2 more recommendations... Although these are set around WW2, they are not combat movies... But rather they show the other
side of war... The homefront & war's aftermath. The first is "Since you Went Away" starring Joseph Cotten & Claudette Colbert;
I tell you, they don't make women like her anymore!! If I were a war pilot, I'd paint her image on the nose of my plane!!
The second is "Best Years of our Lives" with Fredric March, Myrna Loy and Dana Andrews;
Both great movies from the Hollywood Golden age!!
