6. Cora Smith
Played By: Lana Turner
Movie: The Post Man Always Rings Twice (1946)
Most young women in dead-end jobs dream of being whisked away by a handsome stranger. Cora Smith makes the dream real, with a pro-feminist spin. Instead of running off to an ambiguously bright future in parts unknown, she stays right where she is, murders her old, boring husband, and upgrades herself from worker to boss. Not the least suspicious way to come up, but we respect the forward life improvement either way.
