During the time Smith starred with Fuller in "Laramie," the two had a wonderful on and off screen chemistry and would even meet some familiar, as well as unfamiliar, guest stars who went on to bigger and better things. When "Laramie" ended in 1963 after a 4-season run and 124 episodes, Fuller moved on to the cast of "Wagon Train" where he created part of a character modeled after himself, while Smith found himself a victim of typecasting as Slim Sherman.
