5. Meredith Johnson (Demi Moore) – Disclosure (1994)

Why She's a Basterd: Man-devouring bigwig Meredith Johnson sexually harasses corporate wimp Tom Sanders (Michael Douglas).

Then the cutthroat harpie charges him with assault, before plotting to make her crappy co-worker look like a useless halfwit by undercutting his efforts with a defecting client.

Sample Quote:
Meredith Johnson: You get back in here and finish what you started or you're fuckin' dead. You are FUCKIN' DEAD!

What She’d Do To Tarantino's Nazis: Seduce ‘em. Sue ‘em. Scalp ‘em.
