Communist Party Influence?

The modern history position is that the Marshall Plan went into effect shortly after WWII, within months. Actually, I think it really started in 1948 or 1949, with President Truman's second term. We were ready and willing to forgive the Germans, though not so ready to forget. Maybe this was a widespread point of view near Christmas of 1945, but I'm not so sure.

There was a lot of talk about Communist Party influence on film making later, along with the rest of the building "Red Scare" in 1948 to 1954. We suffered a string of strategic setbacks: the blockade of Berlin, the explosion of the Soviet Union's A-bomb, the loss of China to Communism, the Korean War, etc. We also discovered real, genuine spies in our midst: the Rosenbergs, Klaus Fuchs, Alger Hiss, etc. None of them were discovered by "Tailgunner Joe," but there were real spies here. As there is no reaction like an overreaction, Americans started to see Communists everywhere and that led to the Hollywood Blacklist. However, that doesn't mean that there was no Communist Party influence on film making.

I don't think that I have ever recognized that influence within a film prior to this one. The facts are wrong and the propaganda is inconsistent with what the history I've read says was the mainstream point-of-view. On the other hand, this film is in lockstep with Soviet Union propaganda that was pushed well into the 1960's. I am curious as to whether there are any clear fingerprints on its production indicating a solid connection to Communist front organizations.
