The least that we can say is that John Ford was faithful to his movie sites. Monument Valley comes immediately to mind, of course, but what about Beale's Cut?
John Ford (d), Bert Glennon (p), Stagecoach, Walter Wanger, 1939.
John Ford (d), George Scott (p), Straight Shooting, Universal, 1917.
John Ford (d), George Schneiderman (p), The Iron Horse, Fox, 1924. Beale's Cut is "playing" Brandon's Pass.
Here's an interesting site about the Cut as a filming location.
