What Ever Happened to Baby Jane? (1962)

In Robert Aldrich's Grand Guignol classic horror film:

• the two legendary screen rivals dueling onscreen - with the many scenes of ex-child actor and sister 'Baby' Jane Hudson (Oscar-nominated Bette Davis) terrorizing wheelchair-bound, hungry, crippled ex-movie star sister Blanche Hudson (Joan Crawford)
• Baby Jane driven insane by feelings of jealousy (Blanche's success as a movie star while her career fizzled) and guilt (thinking she had crippled Blanche by running the car into her in an early scene)
• her petty tortures including the servings of "din-din": a dead pet parakeet and roasted rat
• the scene of a grotesquely made-up Jane practicing "I've Written a Letter to Daddy" while dressed in a baby-doll suit (with her hair in golden curly locks) to corpulent gigolo pianist Edwin Flagg (Oscar-nominated Victor Buono in his film debut) in a demented attempt at a comeback as Baby Jane
• Blanche's excruciating attempt to make her way down the staircase to phone for help - when Baby Jane unexpectedly arrived home
• Jane's response to Blanche's helplessness in her wheelchair: ("You wouldn't be able to do these awful things to me if I weren't still in this chair") - retorting: "But-cha ARE, Blanche! Yah ARE in that chair!"
• the concluding beach scene in which a dying Blanche revealed the truth, with her final words, of the accident years earlier (Jane hadn't crippled her after all) with Jane's astonished reply: "Then you mean, all this time we could've been friends?"
• the film's end in which a totally insane but deeply happy Jane (shot in soft focus) purchased two strawberry ice cream cones, then danced and spun as a crowd gathered around her, as two policemen located Blanche's body (with an ambiguous fate) in the sand
