Jane Krakowski was very vocal about the fact she considered Anita Morris' performance legendary and she didn't want to imitate her in any way. I think the way they went with her "A Call from the Vatican" in the revival was quite solid even if it seemed gimmicky to some people, the way it was performed definitely exhalted Carla's sexuality.
Anita Morris is one of a kind and her moves in NINE will probably always be attached to the memory of the show in any revival or production, she was just too brilliant to surpass. As I said in another thread, she moved like she had no bones, and she embodied sex without being obnoxious or trashy.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
