Bette Davis and Joan Crawford’s feud was epic….
Davis and Crawford were filming "What Ever Happened To Baby Jane?" together when Davis decided to install a Coke machine in her dressing room, per Harper's Bazaar. Normally this wouldn't be an issue, but it just so happened that Crawford sat on Pepsi's board of directors, and Davis installed the Coke machine simply to taunt her.
When Joan died,
“You should never say bad things about the dead, you should only say good. Joan Crawford is dead. Good.”
- Bette Davis
