I first saw the film Stagecoach many years ago, though not quite as far back as its premiere, which was in 1939. John Ford directed it. The robber is played by the young John Wayne. The absconding banker looks remarkably like Warren G. Harding, but isn't (Harding died in 1923).
To my delight I found out that Stagecoach has an Oregon connection. It's based on the story "Stage to Lordsburg" (1937) by Ernest Haycox (1899-1950), a writer who was born in Portland and wrote most of his works here.
Ernest Haycox, Jr. gives more of the story in the Fall 2003 issue of the Oregon Historical Quarterly, and in his biography of his father (On A Silver Desert: The Life of Ernest Haycox, also published in 2003). He notes that in 1940 Haycox built a large Georgian house in the West Hills that is now a historic landmark. It's on SW Humphrey Boulevard with a fine view to the north and east.
The neighborhood today is the home of doctors, lawyers, captains of industry, and Old Portlanders. No John Waynes live nearby, but only three lots separate it from the home of another man in the W's, who like John Wayne's character in Stagecoach has had some troubles with money and the government.
