Fourth screen appearance of Darren McGavin (Soldier in Hospital reading the comic strip, uncredited). He began his career working as a set painter at Columbia Pictures.
Arthur Q. Bryan (train passenger in the club/sleeping car) speaks with the voice he created for Warner Brothers' Bugs Bunny cartoon series character 'Elmer Fudd'.
The November 1945 release date of the film caused an anachronism in the plot: the traveling Kent character is en route to Japan, via San Francisco, and mentions at least three times he is off to war - but the war ended in September.
Speaking of the Nixie comic continuing while he is stationed in the Pacific theater Kent says, "Watch what happens when he whistles in the ear of that white horse." In Japanese propaganda photos, Emperor Hirohito was often shown riding his majestic white stallion Shirayuki (to make the short emperor look taller). In the US that horse became a symbol of Hirohito's power and position. Knocking him off that high horse was a popular image.
Costume designer Travis Banton created Rosalind Russell's on-screen looks for this and another six of her films, until 1948. They would reunite in 1956 for the original Broadway production of 'Auntie Mame', for which he designed her character's flashy costumes.
