According to documents in the Twentieth Century-Fox Records of the Legal Department at the UCLA Arts-Special Collections Library, the studio purchased the rights to Paul I. Wellman's novel for the sum of $35,000. W. R. Burnett, Robert Hill, Wanda Tuchock, F. Hugh Herbert and Lamar Trotti all worked on different versions of the screenplay, according to studio records The Screen Writers' Guild Arbitration Committee awarded sole credit to Trotti, however. Gene Tierney was originally cast as Julia Norman, but she declined to appear in the film and was replaced by Anne Baxter. Tierney was then suspended by the studio. In a Los Angeles Times article Tierney stated, "There is certainly nothing personal in the issue that has arisen between Twentieth Century-Fox and myself. I simply could not undertake the part in Walls of Jericho because I did not believe it was right for me. I could not fathom the character of the girl although it was the lead in the picture. It was particularly difficult for me to refuse this role because John Stahl is the director and we have had such excellent association with Leave Her to Heaven. Nevertheless, I felt it would be a great mistake for me to appear in this new film." A Hollywood Reporter news item of September 15, 1947 announced that Robert Preston would be borrowed from Paramount for the role of Tucker Wedge. The Variety and Hollywood Reporter preview reviews list a running time of 111 minutes suggesting that approximately five minutes was cut for the final release prints. A radio adaptation was broadcast on the Screen Guild Players program on January 27, 1949 and starred Cornel Wilde and Claire Trevor. Lux Radio Theatre broadcast an adaptation with Wilde and Terry Moore on March 8, 1955.
