This was Walter Pidgeon's final film under his MGM contract. He had been with the studio for 19 years.
At the beginning of the film, Bradford arrives at his steel mill in a 1956 Imperial Crown Imperial Limousine. Only 119 were made. In excellent condition in 2018 these cars could be worth upwards of $100,000 or more. Imperial was Chrysler's luxury line at the time, much as Lincoln is to Ford or Lexus is to Toyota.
Upon James Cagney exiting lawyer Leland G. Spottsford's office building, a theater marquee and film posters can be seen advertising Casino de placer (1956), which was the previous film directed by These Wilder Years (1956) director Roy Rowland.
