During the sneak preview performance, first-time feature director Fred Zinnemann noticed that all the MGM executives got up and walked out together. He later found out that it had nothing to do with the film. They had just gotten the news that Carole Lombard had been killed in a plane crash.
In the drive-in restaurant scene, the waitress who kisses the patron in the car next to Jane (Marsha Hunt) and Gerald (Lee Bowman), who she then identifies as her husband, is Ava Gardner.
The plot was based on an entry in MGM's "Crime Does Not Pay" series (They're Always Caught (1938)) directed by Harold S. Bucquet. Interestingly, Fred Zinnemann had started his American directorial career in the series.
This film did well at the box office, earning MGM a profit of $161,000 ($2.8M in 2021) according to studio records.
At the beginning of the film is a shot of a city's downtown taken from atop a skyscraper. At the center is a tall office building with a sign on top, seen from behind. (The writing is backwards.) It clearly reads, "First National Bank of Omaha".
