You may not recognize the name immediately, but for my generation and older, she was the clueless matriarch of the wealthy family in Soap. Younger people will probably know her as Mona from Who’s the Boss?
The coolest thing Katherine did though was appear in Terry Gilliam movies, namely personal favorites Time Bandits (the ogre’s wife) and Brazil (the hero’s mother who keeps getting plastic surgery).
Thanks for being convincing as the characters you played, namely the one from Soap since you came from a background that was the total opposite!
