The Iron Curtain

The music in the film became the subject of a minor but telling episode in the Cold War. Alfred Newman, the illustrious head of the 20th Century-Fox music department, scored this picture. It's not readily known who decided to incorporate genuine Soviet music into the film, but Newman's score featured compositions by the USSR's finest: Dmitri Shostakovich, Sergei Prokofiev, Aram Khachaturyan and Dominik Miskovský. All four composers signed (or were ordered to sign) a letter of protest that claimed their music was appropriated via a "swindle" in order to accompany this "outrageous picture". No individuals were named, except "the agents of the American Twentieth Century-Fox Corporation". None of the composers would have had the opportunity to have seen the movie, thus it is to be assumed that they were put up to this protestation by the Stalin regime. Interestingly, the four "protesting" Soviet composers were at that same time under severe scrutiny themselves for composing music that was construed as subversive to the Soviet state, and for a time their heads were on the chopping block. So it's also to be assumed that the four filed this protest as a gesture of their loyalty to Iosif Stalin (or, more likely, to save themselves from being executed). In any case, these composers were often obliged to make "statements" that they personally had nothing to do with. Coincidentally, Hollywood at this same time was beginning to be scrutinized by the House Un-American Activities Committee for signs of "subversion" of the American state, resulting its its own blacklist.

Film debut of Berry Kroeger.

The fourth of five movies with Dana Andrews and Gene Tierney, and the second of three where they are paired together as a couple, or would-be couple. The other movies are Belle Starr, Tobacco Road, Laura, and Where the Sidewalk Ends. Only this movie, Laura and Where the Sidewalk Ends are they paired as main characters.

Said to be one of the first Cold War movies.

The song "You'll Never Know" plays at the restaurant when Dana Andrews dances with June Havoc; Alice Faye, who Dana starred with in Fallen Angel, sang the song for which this instrumental version was based.
