Ed Begley Jr. appears as the grandson of the first suspicious death at Valleyview, who sets off Quincy's investigation. During their first meeting, Quincy is impressed by the boy's knowledge of medical terms and asks, "Are you a doctor?" Ed replied, "I'm gonna be," and he was right. In 1982, Ed would star in the groundbreaking medical series St. Elsewhere as Dr. Victor Erlich.
Jack Klugman and Robert Webber were two of the Twelve Angry Men in the movie of that name. Ed Begley, Sr. was another.
