I was first introduced to the actress Marian Mercer when I was in college and she appeared in the soap opera-sitcom 'Mary Hartman, Mary Hartman' as Wanda Jeter (nee Rittenhouse). As with several other women living in Fernwood, Ohio, I developed a crush on her. Ms. Mercer brought a charming sophistication to the role.
And you might not agree, but I think it's evident even in this scene:
Sadly, Marian Mercer passed away at the age of 75, around the same time as Jackie Cooper. She was also known in Toobworld for her roles in 'It's A Living' and 'The Wacky World Of Jonathan Winters'.
