Cassandra Becomes Samantha
Even though she was Sol’s first choice, Tammy Grimes couldn’t leave her Screen Gems contract to take the job she had auditioned for. Instead, the creators hired Elizabeth Montgomery and renamed the character Samantha. It’s pretty impossible to imagine Samantha (or Cassandra) played by anyone else.

Grimes continued her acting career, appearing on Broadway and in films. She also got into the humanitarian sphere, advocating for Unicef and other organizations. Maybe it was a good thing that Grimes didn’t end up working on Bewitched. She passed away at the age of 82, seemingly avoiding the Bewitched “curse.” But more on that later.
