Well, why not give it a shot? In my opinion and off the top of my head:
— O de H in "the heiress"
— Meryl Streep in "out of Africa"
— Katharine Hepburn in "the lion in winter"
— Audrey Hepbrun in "the nun's story"
— Faye Dunaway in "Bonnie and Clyde"
O de H -The Heiress
Elizabeth Taylor - A Place in the Sun
Joan Crawford - Mildred Pierce
Barbara Stanwyck - Double Indemnity
Bette Davis - Jezebel
Reading these lists is a blast. Coming up with a definitive list would take me lots of time. But I will list a few performances not mentioned that deserve mentioning. Maybe it will inspire someone else to make their own additions.
Rosalind Russell-- Picnic
Audrey Hepburn--Wait Until Dark (someone did mention this one)
Barbra Streisand--The Way We Were
Patty McCormick--The Bad Seed
Judy Holliday-- Born Yesterday
Angela Lansbury--The Manchurian Candidate
Audrey Hepburn-- Roman Holiday
Hilary Swank-- Boys Don't Cry
