This western movie is a re-working of Miguel de Cervantes y Saavedra's Don Quixote legend (The Ingenious Gentleman Don Quixote of La Mancha) transferred to an American western setting.
This 1971 cinema movie and the same year's The Barefoot Executive (1971) were the first ever theatrical feature films of actor John Ritter. Both pictures were Walt Disney productions.
The ranch seen in the film was the Oliver M. Lee Ranch near Alamogordo in the American state of New Mexico, USA.
