Movie: Out of the Past (1947)
Unlike most of the low-aiming femmes on this list, Kathie Moffat isn't in it for a trivial sum of money or to escape a loveless union. Granted, those things are factors, but in the third act of Out of the Past, she proves her true G when she effectively pits crime boss and lover Whit Sterling (Kirk Douglas) and former lover Jeff Bailey (Robert Mitchum) against each other, removing Whit from the scenario so she can proudly declare that she's running things now. You can be the king, but watch the queen conquer (length of her reign before death notwithstanding).
