In 1950, the film became an object of attention by members of Congress, who saw it as pro-Soviet propaganda. Davies was largely silent on his role in the film, though he did submit a letter to the House Un-American Activities Committee (HUAC) in 1947. Called to testify under oath before Congress, Jack L. Warner at first claimed that the film was made at the request of Davies, who with the approval of FDR had asked Warner Bros. to make the film (this version of the facts was confirmed by Davies' letter as well). Warner later recanted this version, stating that Harry Warner first read "Mission to Moscow" and then contacted Davies to discuss movie rights.
