I worked with her (circa 1990). She was an Actors Studio devotee (and member), and really thought and approached everything with those sensibilities. The stand-up demeanor/persona was in effect a kind of character; her general process/MO was not a comedian's. She was a serious theater actor (and writer) and I thought a terrific director, though from what I understand she didn't do much directing, which is sad. The piece we worked on featured a cast of (all) women, and she had a great ability to inspire performances without a lot of peripheral talk. Like many instinctive actors who direct, she knew that less is more. And that actors need to be left alone. She was also a task-master. We sat down with the script, and I said "so are we gonna go through this line by line?" She paused, not for humorous effect, and said "word for word." Which we did, over hours. Over subsequent years, I'd often see her on the street, we were neighbors, and she could be disarming and droll. But she was never remotely comical directing or parsing text. Her work ethic was her life, and if you didn't share it, she had little patience with you, appropriately. She was very kind and generous to me, and I treasure the memory of our brief experience together.
