The 1958 Chrysler New Yorker sedan, California license number NNX 246, driven by Richard Widmark in the film, appears in episodes 14 and 19 of the fourth season of Highway Patrol (1955).
Broderick Crawford's character, C. Errol Madre, contacts KAOS on a special phone. He begins the conversation saying, "2150 to headquarters", ending with "Ten-Four." This is a nod to his long-running role as Chief Dan Mathews in the series.
