Answer: The first actress, Cloris Leachman appeared in the TV movie which ended up being the pilot for the series. At the time, Leachman was already starring in her own TV series "Phyllis" (a spin off her role in "The Mary Tyler Moore Show"). This was actually the 2nd TV movie meant to be a pilot and the first one wasn't picked up. It's likely she thought the show would be picked up. After season 1, in which Carolyn Jones played the role, ABC was slow to make a decision to pick up the series for season 2 and CBS picked up the series. When CBS picked up the series, they changed the time setting of the show and replaced all the actors, with the exception of Carter and Waggoner (with Waggoner playing a different role technically), resulting in Beatrice Straight being cast.
