William Schallert Became The SAG President
One of the other biggest stars in the cast other than Duke was William Schallert, who played Martin Lane. But in addition to this TV role, he had roles in a large number of movies and was active in the movie business. Eventually, Schallert became the Screen Actors Guild president from 1979 to 1981 and still remained very active in SAG projects after his tenure drew to a close.
