Olivia de Havilland (Catherine Zeta-Jones)

This two-time Oscar winner was a contemporary of Davis and Crawford’s. She didn’t have a part in Baby Jane, but famously stepped into Crawford’s role in Hush…Hush, Sweet Charlotte when Crawford dropped out. Crawford cited illness, but Davis always thought it was because Crawford didn’t want Davis stealing her thunder again. Sweet Charlotte was not a sequel to Baby Jane, but it was a similar movie and was slated to pair Crawford and Davis again until Crawford left the project.
