The original title of the film was "Duel in the Wind." Lee Van Cleef came up with the Italian title while discussing the movie with John Phillip Law who sighted the film was a "man to man" story. Van Cleef remarked, "Why don't they call it 'From Man to Man'?" The Italian producers liked how it sounded in Italian ("Da Uomo a Uomo") so much they used it. And then the film was subsequently retitled "Death Rides a Horse" in English speaking markets, which Law said he never liked.
When we first see Bill Meceita (John Phillip Law), he is practicing his shooting. The first revolver he shoots, a six-shot Colt Peacemaker, turns out to be a 9 shooter, and the second is an 11 shooter.
At about 38 minutes the barman is thrown out of window and when he re-enters the saloon he is shot, after which he falls into the street. He is then seen being thrown out of the bar a second time almost immediately afterwards.
