Hoss Cartwright befriends philosophical drifter Will Smith (Lonny Chapman), a brilliant poet but a chronic alcoholic. Characteristically, Hoss tries to reform Will-only to discover that his new friend is not the rootless vagabond everyone thinks he is. Jorja Curtwright is cast as the obligatory "woman from the past," Lydia Evans (note that last name-it's an important plot point). Written by Donn Mullaly, "The Genius" was originally telecast on April 3, 1966. ~ Hal Erickson, Rovi
