Bette Davis in Sunset Boulevard, or Whatever Happened to Baby Jane. Or Of Human Bondage.

Katherine Hepburn in Suddenly Last Summer. And her son. He trolled Liz in a transparent bathing suit to attract third world young men for him to prey upon, and in the end they mobbed him on the beach and tore him apart.
