Robert Blake and DeForest Kelley
Both in episode 3-25: No Amnesty for Death.
shareYou'd be amazed at how many future stars appeared both on this show and "Wyatt Earp". I've seen Harry Dean Stanton and Stefanie Powers, among others. Allison Hayes, who played the "Fifty-foot Woman", had a semi-regular gig as Bat's semi-regular girlfiend, playing a b-girl at his bar in Dodge Ciry.
