Mission to Moscow - Michael Curtiz

"Mission to Moscow" was made at the behest of F.D.R. in order to garner more support for the Soviet Union during WWII. It was from the book by Joseph E. Davies, former U.S. Ambassador To Russia. The movie covers the political machinations in Moscow just before the start of the war and presents Stalin's Russia in a very favorable light. So much so, that the movie was cited years later by the House Un-American Activities Commission and was largely responsible for the screenwriter, Howard Koch being Blacklisted.
