Many cast members in studio records/casting call lists did not appear or were not identifiable in the movie. These were (with their character names): Howard M. Mitchell (Nicholas), Jacqueline Miller (W.U. Girl), Ralph Sanford (Policeman), John Sheehan (Policeman), Cliff Nazarro (Milkman), Phillip Terry (Whitley's Assistant), Lloyd Ford (Ethel's Husband), Rex Evans (Photo Insert of Hermann Göring), and Bobby Watson (photo insert of Adolf Hitler). (W.U. Girl undoubtedly stands for Western Union Girl, but no telegrams were seen delivered.)
