Elizabeth Montgomery wasn’t the only friend that Agnes Moorhead made during filming Bewitched. Apparently she and Dick York became very close during the first three seasons of the show, which may seem amusing as their two characters despised each other on camera. Off camera, however, the two were thick as thieves.
In fact, Moorhead was so loyal to York that once he left the show, she allegedly argued with and bothered Dick Sargant, York’s replacement. Perhaps because she resented the replacement, Moorhead is said to have upset Sargent enough to make him cry–or at least very bothered and emotional. That’s some loyalty.
