As a child, Jane Hudson (Bette Davis) was a pampered vaudeville star known to the world as Baby Jane while her younger sister, Blanche (Joan Crawford), led a quiet life in her considerable shadow. Decades have passed and now Blanche is a beautiful, talented movie idol and Jane a lowly extra. When a car accident cripples Blanche, binding her to a wheelchair, Jane sees her opportunity for revenge and assumes the role of caretaker. Her newly gained power completes the transformation of the sugar-sweet child star into a nightmarish caricature of Baby Jane. As she does everything she can to make her sister's life a living hell--including feeding Blanche a dead rat and brutally beating her when she tries to phone for help--Jane plots a comeback, aided by shifty musical director Edwin Flagg (Victor Buono).

Director Robert Aldrich (KISS ME DEADLY) composes the strangest and most unsettling film of his career, creating a blueprint for future psycho-thriller filmmakers to follow. Renowned offscreen rivals Davis and Crawford revived their flagging careers with two stunning performances, and Buono received an Academy Award nomination for his supporting role. Creepy, campy, grotesque, and terrifying, the wildly over-the-top WHAT EVER HAPPENED TO BABY JANE' is a disturbing and unforgettable film.
