"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie onNovember 26, 1951 with Adolphe Menjou reprising his film role.
Clark Gable wanted the name of the movie changed because shortly before filming he married Lady Silvia Ashley and did not want people to make comparisons.
A young Bill Hickman can be seen as one of the members of Clark Gable's pit crew. Hickman was famous as one of the top movie stunt drivers in Hollywood for many years, and his most notable on-camera role was as the middle-aged, bespectacled driver of the black Dodge Charger that is chased by Steve McQueen's green Ford Mustang in the film Bullitt.
At 20:26 in the film, a close-up shows the Sports Final section of the Bainsville daily paper. Under Barbara Stanwyck's photograph (as Regina Forbes) three pictures of "sports stars" are shown: Kathryn Grayson, Walter Pidgeon and Gene Kelly. This must have been an inside-joke as the film and the stars shown were all under contract with MGM.
Its failure caused Clark Gable to fall out of the Top Ten Box Office stars list.
The film featured short-track midget car racing, a highly popular form of auto racing in post-World War II America. From the mid-1930's through the mid-1960's, most drivers who aspired to race in the famous Indianapolis 500 usually started competing in the midgets, then sprint cars (similar in looks, but more powerful and faster than midgets), then to "championship," or Indianapolis-type cars.
The finale of the film takes place at the Indianapolis 500. The actual 1950 running of the 500 was used for these scenes. The actual driver of the 17 car for the 1950 Indy 500 was the real Joie Chitwood, featured earlier in the film as the owner of the Thrill Show Brannan was working in. See the Goofs section for continuity issues created by using actual race footage.
