2. Phyllis Dietrichson (Barbara Stanwyck) – Double Indemnity (1944)

Why She's a Basterd: Suburban harlot Phyllis Dietrichson hypnotises insurance plod Walter Neff (Fred MacMurray) with his own lust, luring him into her husband-elimination plot with a flash of shapely leg. “I’m rotten to the heart.” gabs the fatal femme.

Okay, she’s as subtle as an ice-cube shower but, frankly, that’s what Neff should have jumped into before falling under her spidery spell.

Sample Quote:
Phyllis: We're both rotten.
Walter Neff: Only you're a little more rotten.

What She’d Do To Tarantino's Nazis: Charm some blighter into trying to kill the bally lot of them.
