Where the Sidewalk Ends is a 1950 American film noir directed and produced by Otto Preminger. The screenplay for the film was written by Ben Hecht, and adapted by Robert E. Kent, Frank P. Rosenberg, and Victor Trivas. The screenplay and adaptations were based on the novel Night Cry by William L. Stuart. The film stars Dana Andrews and Gene Tierney.
The film narrative concerns ruthless and cynical Mark Dixon (Dana Andrews), a metropolitan police detective, who despises all criminals because his father had been one. Considered a classic of the film noir genre, the brand of violence shown in the film, "lurking below urban society", is an important noir motif.
