She's been nominated three times - Best Actress in a Leading Role for The Grifters, Best Actress in a Supporting Role for Enemies: A Love Story, and Best Actress in a Supporting Role for Prizzi's Honor.

And she's brilliant in all of them. I'm choosing the role she won for just to help me narrow it down because seriously, they're all amazing.

Maerose Prizzi in Prizzi's Honor. Maerose is not the lead - that would be Kathleen Turner's Irene - but she is far more pivotal and fascinating. Kathleen Turner acknowledged as much at the time. She knew Anjelica had the plum role with Maerose but she agreed to play Irene anyway so she could work with John Huston. Everybody involved had to have known that Anjelica would take the Oscar if anyone did - not only is Maerose key but Anjelica owned her.
