Here is a picture of Bewitched star Elizabeth Montgomery when she was very young. Bewitched was a big paradigm shift in how people saw witches. The usual look for a witch was an old, disgusting crone. Elizabeth Montgomery couldn't be farther from old or disgusting. In the show, she would usually try to help her husband with her magic, but PLOT TWIST - he never wanted her to use her magic. That's because things would usually get worse once she started using her powers.
Will Ferrel and Nicole Kidman would later star in a film adaptation of the show, but it didn't connect with fans. People weren't even as sick of remakes back then as they are now. I guess there wasn't really a desire to see the show made into a movie, and the movie just wasn't very good.
