Movie, TV and stage actor Robert Horton has died » Boyd Magers at the Western Clippings website has reported that Robert Horton, an actor best known for the western TV series “Wagon Train” has died. He was 91 years old. Horton played scout Flint McCullough on “Wagon Train” from 1957-1962, quitting the series to explore other pursuits as an actor. He left the show right around the time the star, Ward Bond, died in 1961 [actually he died in 1960], and the series moved from NBC to ABC. He was replaced by Robert Fuller. [Technically Horton was not replaced by Fuller. Horton left in 1962, Fuller joined the show in 1963.] Horton made many film appearances, including Lewis Milestone’s “A Walk in the Sun” and the cult sci-fi favorite, “The Green Slime.” He was on such TV shows as “The Lone Ranger,” and also several dramatic anthology series. On one of these, “King’s Row,” he played the role Ronald Reagan made famous in the movie version. Another interesting television appearance was as an amnesiac in the series “A Man Called Shenandoah.” Along with his TV and movie work, Horton appeared often on stage. Possessing a fine singing voice, Horton enjoyed success in musical theater, including a 330-performance run on Broadway in a musical version of “The Rainmaker.” Receiving many lifetime awards for television, including the Golden Boot Award honoring western actors, Horton stopped acting in 1989 and quit making personal appearances in 2009. Horton died in a Los Angeles rehabilitation center. Robert Horton always seemed to me like the prototype for a TV (as opposed to movie) western star. His face was rugged, but his voice was soft and his manner low-key -- perfect for the cool medium of television.
