Even though the episode "Seven Hours to Dawn" (Sept. 18,1965) was scheduled to air first, Morgan Wooodward himself said in the Gunsmoke reference book that this episode was his first hour long episode.
Morgan Woodward had previously appeared in the Gunsmoke episode, "Potato Road" (Oct. 12,1957), but with this episode he began a run of many guest spots on the series. In fact he appeared in more episodes than any other guest star, a total of 17 as many different characters. He is best known as the Walking Boss in Cool Hand Luke (1967), his other film credits include, The Great Locomotive Chase (1956), Gunpoint (1966), Firecreek (1968), The Wild Country (1971), One Little Indian (1973), Killing of a Chinese Bookie (1976), Girls Just Want to Have Fun (1985), and Dark Before Dawn (1989). He was a semi regular on the series, The Life and Times of Wyatt Earp (1955-61) and a regular on Dallas (1980-87) replacing sort-of Jim Davis' character.
