Gene Autry, Ann Miller, Jimmy Durante (shown) and George "Gabby" Hayes star in "Melody Ranch" from Republic Pictures in 1940.

One place this film wasn't shot was the Melody Ranch Motion Picture Studio in Placerita Canyon. At the time, Melody Ranch wasn't a physical place; it was the fictional setting of Autry's radio show of the same name, which first broadcast on CBS Jan. 7, 1940. The show was initially titled "Double M Ranch" (because it was sponsored by Doublemint chewing gum), but the name was changed to "Melody Ranch" early in its first year.

This film, in which Autry plays — you guessed it — a radio show host, followed later in the year. Filming took place over three weeks from Sept. 16, 1940, to Oct. 5, 1940, in the Alabama Hills (US395 above Lone Pine), Mammoth Lakes, Red Rock Canyon State Park (Cantil/Mojave Desert) and at the Republic Studios in North Hollywood. The film was released Nov. 15, 1940, and cost $181,275 to make.

The radio show's theme song was "Back in the Saddle Again." The song isn't used in the eponymous film. One iconic song in the film is "Stake Your Claim on Melody Ranch," which you can hear performed by Autry and Miller, here:

Autry purchased the old Monogram Ranch (known after 1941 as Placeritos Ranch) in late 1952 or January 1953 from the widow of owner Ernie Hickson, who died in January 1952. Autry renamed it for his strong "Melody Ranch" brand. (So, the radio show wasn't named for the ranch; the ranch was named for the radio show.) Except for a wartime interruption from Aug. 1, 1943, to Sept. 23, 1945, just after war's end, Autry's radio show continued to air on CBS until May 16, 1956.

"Melody Ranch" (the movie) also stars Barton MacLane, Barbara Jo Allen, Jerome Cowan, Mary Lee, Joe Sawyer, Horace McMahon, Clarence Wilson and William "Billy" Benedict.
