There are many characters in Bewitched, a fantasy television sitcom.
Samantha Stephens (Elizabeth Montgomery) is a witch and the show's protagonist. She's married to a mortal named Darrin Stephens and has two magical children by him. Samantha often has difficulty adjusting to mortal life, even though she is trying to give up using her powers. She is perhaps the most sensible character in the show; she enjoys her mother's company and is able to take her jabs at mortal life with ease. She is optimistic and treats everyone with respect be they magical creatures, powerful witches and wizards, or ordinary people.
Darrin Stephens (originally Dick York, later Dick Sargent) is a mortal married to Samantha. He did not know she was a witch until she told him after their marriage. He works as an executive at the McMann and Tate advertising agency. Dick York was unable to continue his role as Darrin because of a severe back condition, the result of an accident during the filming of They Came To Cordura in 1959. Starting during the third season, York's disability caused ongoing shooting delays and script rewrites. After collapsing while filming the episode "Daddy Does His Thing" and being rushed to the hospital in January 1969, York left the show. Dick Sargent, who would go on to play Darrin in the sixth through eighth seasons, was cast for the role that same month.
Endora (Agnes Moorehead), is Darrin's chief antagonist of the series and Samantha's mother. Like all witches, she never reveals her surname, indicating to Darrin that he would be unable to pronounce it. Endora loathes mortals and disapproves of Darrin, as do many of Samantha's relatives. Endora refuses to even use Darrin's name, alternatively calling him "Derwood", "What's-his-name", "Darwin", "Dum-Dum", etc., all much to his annoyance. She refers to him as "Darrin" only eight times during the entire series. Endora's ploys to provoke a breakup always fail as Samantha and Darrin's love overcomes every obstacle. Even though Endora casts countless farcical spells on Darrin, she never attempts to destroy him outright. During the first season, Endora threatens her warlock husband Maurice that she will not have a human being on her conscience. It was one of not few times when Endora went out of her way to protect Darrin from Maurice (See episode 1x10). Endora once lets Maurice kiss her, but if she finds out that he just kissed her (and disappeared) and she gets a bug (with which she can't use her powers any more), she gets furious until Maurice surprisingly comes back, gives her an antidote, and takes her to "the place we used to go to on the Milky Way" to have dinner there together. She doesn't get along with Darrin's mother, Phyllis Stephens (because Endora gets along too well with Phyllis' husband, Frank), but they are civil to one another in, what Samantha calls "killing one another with kindness". Endora does dote on her grandchildren, Tabitha and Adam, and to them, she is called "Grandmama".
