Of the twenty-three actors and actresses who appeared in ten or more episodes, only three were alive at the 50th Anniversary in 2014. They were Bernard Fox (Dr. Bombay), who was eighty-seven at the time, and also holds the record of enjoying the greatest longevity of any of those actors or actresses. The others were Diane and Erin Murphy (Tabitha), who were fifty. They were born in 1964, the same year this show debuted. UPDATE: Bernard Fox died at the age of eighty-nine on December 14, 2016.
The show's now-iconic animated opening credits were created by Hanna-Barbera Productions, creators of such beloved 1960's cartoons as Les Pierrafeu (1960), Les Jetsons (1962), and Scoubidou (1969). These cartoon characters also guest-starred on "The Flintstones."
Agnes Moorehead had a strong working relationship with Dick York, and when he was replaced by Dick Sargent, she did not take the decision well. On Sargent's first day on the set (for a script reading), and in front of the entire cast (including Sargent), Moorehead very slowly but firmly stated, "I don't like change."
