Let’s not forget FOR WHOM THE BELL TOLLS, an extremely fine film which doesn’t dwell on communisim but on fighting Franco’s forces.
And who can forget DAYS OF GLORY with Gregory Peck.

I have seen most of these movies and must remember that the Soviets were our allies during WWII which is probbly why they were made, complete with their commie “paradise” themes.
Among other non political films at the time were DRAGONSEED, about the Chinese in the war, CROSS OF LORAINE, about the French in the war(ok, so the film was fiction), EDGE OF DARKNESS about the Norwegeans in the war, but the films about Russia were the most political pro commie films I’ve seen.
I prefer the term used by one of my history teachers in high school. He called us and the commies co-belligerants.
