Olivia de Havilland and Joan Fontaine
Olivia de Havilland and Joan Fontaine are both Academy Award winners and known for their film roles in the 1930s and ’40s. Apparently, their feud began in childhood, when they would compete for attention from their mother. They continued to fight over men, film roles, and even an Oscar. Joan, who died in 2013, claimed Olivia never told her of their mother’s passing. Meanwhile, Olivia says Joan was too busy to attend services.
