This is a fine, brief documentary on the Old Tucson film studio in Arizona, which started in 1939, built by Columbia for "Arizona" (starring William Holden).
If this film is correct, the studio went downhill for a while until Howard Hawks decided to make "Rio Bravo" there, and then the studio took off -- becoming a tourist destination for the public in 1960, and the site of countless Western movies ("Tombstone") and television ("Little House on the Prairie").
The narrator makes a list of the famous people who walked the studio grounds and were filmed there. While that could be said of many places, there probably is no other place on earth quite like this set. Unlike Burbank, this set had only one purpose -- to bring the Old West (even if romanticized) to life.
