"Olivia Mary de Havilland (born July 1, 1916) is an English actress and is the only living star of Gone with the Wind, but there are also actors with smaller roles in said movie who are still alive."
Guess I missed that last part. I was just surprised Olivia is still kickin'.
Olivia’s sister Joan Fontaine is also still alive. At the time GWTW was filmed she was making Hitchcock’s Rebecca also for producer David O. Selznick.
