This was Jack Carson's final theatrical released film before his death on January 2, 1963 at the age of 52.
At the poker game, the talk of the World Series and Chicago alludes to the "Black Sox" scandal of 1919, in which several Chicago White Sox players were accused (but legally acquitted) of having been paid to throw the Series; the operation was bankrolled in part by Arnold Rothstein.
The real Arnold Rothstein was short and fat. David Janssen was neither.
After the poker game, the movie title on the marquee across the street is Another Man's Shoes (1922), a gangster movie now considered lost. (In reality, however, the events of the poker game occurred in late 1928.)
