At the road block, a policeman states they've only seen 18 drunks and 6 guys carrying slot machines. Gambling was still illegal in most of the U.S., with Las Vegas only in its infancy at the time of this film. But organized crime was running illegal gaming spots all over, including New York City. The slot machines mentioned were light years away from the modern ones in use today.
Composer William Lava repeatedly uses a five-note melody cribbed or "sampled" directly from Alfred Newman's composition for the theme from King Vidor's romantic drama Street Scene (1931). This Newman theme was recycled for the theme for I Wake Up Screaming (1941) and it soon became a staple of the studio's noir dramas, used as an oral signifier of the Big City in films like The Dark Corner (1946), Kiss of Death (1947) and Cry of the City (1948).
This film's working title was Smart Money.
