Several people are in studio records/casting call lists as cast members, but they did not appear or were not identifiable in the movie. These were (with their character names): Russell Hicks (President), Ruth Warren (Mother), Forbes Murray (Otis), Harry Hayden (Spokesman) and Clem Bevans (Judkins). A modern source states that John Barrymore's wife, Elaine Barrie was to be in the film, but her scenes were cut.
When John Barrymore, for political reasons, asks for the name of someone who went to Yale, Jack Haley says brightly, "Rudy Vallee!" He was known to be a Yale graduate because one of his biggest hits, in 1937, was "The Whiffenpoof Song," the college song.
