The working title of this film was Walk a Crooked Mile. According to an August 1949 Hollywood Reporter news item, Don Siegel was originally assigned to direct the picture and Alex Gottlieb was to produce. In August 1950, Hollywood Reporter announced that Harold Daniels had been assigned both to write and direct the picture. Daniels' only confirmed credit is for directing, however. The final car chase scene was shot along the cement bed of the Los Angeles River. Reviewers commented on the uniqueness of the location; the river bed has since become a popular filming site.
