Shortly after the film's release, Clint Eastwood wrote to John Wayne, suggesting that they make a western together. Wayne sent back an angry letter in reply, in which he denounced this film for its violence and revisionist portrayal of the Old West. Eastwood did not bother to answer his criticisms, and consequently they did not work together.
The character of Marshal Duncan was played by stuntman Buddy Van Horn, a long-time stunt coordinator for Clint Eastwood, in order to create some ambiguity over whether he and The Stranger are one and the same.
During an interview on Inside the Actors Studio (1994), Clint Eastwood commented that earlier versions of the script made The Stranger the dead marshal's brother. He favoured a less explicit and more supernatural interpretation and excised the reference. Although the Italian, Spanish, French and German dubbings retain it.
Universal Pictures wanted the film to be shot on the studio lot. Instead, Clint Eastwood had a whole town built in the desert near Mono Lake in the California Sierras. Many of the buildings were complete and three-dimensional, so that interiors could be shot on location.
Controversial in its day but still a commercial hit, _High Plains Drifter (1973)_ is listed in the Motion Picture Guide as one of the best Westerns of the 1970s. However, some critics thought Eastwood's direction was too derivative of his mentor Don Siegel and the works of Sergio Leone.
Eastwood scouted the locations himself while driving a pickup truck through Oregon, Nevada and California. He chose the shores of Mono Lake because he considered the area highly photogenic. Additional scenes were filmed at Reno, Nevada's Winnemucca Lake and California's Inyo National Forest.
The Stranger is similar to The Man With No Name persona familiar to Clint Eastwood's Spaghetti Westerns, and they even wear a similar hat. The character in the film has no personal name and is only referred to in the billing as The Stranger.
The Bible verse on the wall of the church is Isaiah 53:3-4 which reads, "He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised and we esteemed him not. Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted"
The town of Lago was built 300 miles away from Hollywood. A 46-man crew of technicians and 10 laborers worked 10-hours a day for 18 days constructing 14 houses and a two-story hotel. They were burned down at the film's completion.
The strange colors make the town of Lago look different throughout the day scenes. Clint Eastwood supplemented this with eerie music, idiosyncratic photography as well as a weird dream sequence all adding to the supernatural atmosphere of the movie.
Any holes in the plot were filled with black humour and allegory to Sergio Leone. Eastwood thought the allegory of the film was "a speculation on what happens when they go ahead and kill the sheriff and someone comes back and calls the town's conscience to bear. There's always retribution for your deeds."
