Eleanor Audley was chosen to voice Maleficent, but she almost turned the role down because she was battling tuberculosis. If her voice sounds familiar to you, she was the voice of Lady Tremaine in Disney's Cinderella, in fact animator Marc Davis used Audley's face as reference when creating both Lady Tremaine and Maleficent. In fact, you can also hear Audley's voice as Madame Leotta at the Haunted Mansion attractions in Disneyland and Walt Disney World.
I can't resist leaving you with one of my favorite scenes from Sleeping Beauty.
Have a Magical Day!!
