Question: Are Olivia de Havilland and Joan Fontaine still alive? And did these sisters ever costar on-screen?

Answer: Olivia de Havilland, who was born on July 1, 1916, and her younger sister, Joan Fontaine, who was born the following year on October 22, are both still alive. Throughout their lengthy careers, they were always very competitive and have had a notoriously rocky personal relationship as well. Not only did they never make a film together, but there were some very public snubs and the pair have gone through long periods of not speaking to each other at all.
