In 1963–1964 Witney had a recurring part as the first wagon master, Buck Coulter, in the first 14 episodes of the ABC Western television series The Travels of Jaimie McPheeters, starring child actor Kurt Russell in the title role and based on a 1958 novel by Robert Lewis Taylor. Dan O'Herlihy played Jaimie's father, "Doc" Sardius McPheeters, and Charles Bronson at mid-season replaced Witney as the wagon master, cast in the role of Linc Murdock. The Travels of Jaimie McPheeters was Witney's first screen acting role.
