Whatever Happened To Baby Jane (1962, Robert Aldrich)
Another classic. I am very close to my sister and I just think sisters can be incredibly cruel to each other. And also, this is a film about faded fame and glamour, and who has and who needs the spotlight. There is absolute cruelty to it. And Bette Davis shows no vanity, I can imagine her saying "make me uglier". That would be my ultimate fancy dress costume – to go like that with my sister.
