There is no visiting marshal in this movie -- perhaps you're thinking of El Dorado, which was a very similar film by the same director and also starring John Wayne.
The film "Green Berets" starring John Wayne was filmed there. At the time John Wayne intended the film to be the first "supporting the men in Vietnam" movie; in contrast to all the anti-war demonstrators and anti-Vietnam footage and speeches.
John Wayne's first movie appearance was not in a western. He is first seen in the movie "Brown of Harvard" in 1926; in which he plays a football player and has no speaking part. His first Western role was in "The Big Trail" (1930) but his breakout role was nine years later in John Ford's "Stagecoach" (1939), the movie which made him a box-office star. When the TV series "Gunsmoke" premiered on TV in 1955, Wayne introduced James Arness in the starring role. (see related link)
