8. Lilly Dillon (Anjelica Huston) – The Grifters (1990)
Why She's A Basterd: The movies meanest mother? Damn close – Lilly is a hard-as-nails career conwoman with balls as big as melons.
As happy getting down and dirty in a verbal cat-fight with her son Roy’s (John Cusack) girlfriend as she is facing down Mafiosi heavies out to give her a beating, this is a woman who will stop at nothing to get her way.
Even if it means seducing her own son. Ew.
Roy Dillon: I guess I owe you my life, Lilly.
Lilly Dillon: You always did, Roy.
What She’d Do To Tarantino's Nazis: Grift them out of their gold, their guns and their trousers.
