Title: List of Bewitched characters
Content:  Samantha Stephens (Elizabeth Montgomery) is a witch and the show's protagonist. She is married to a mortal named Darrin Stephens and has two children by him. The daughter, Tabitha is magical. The son, Adam, is magical as well, as demonstrated in "Adam, Warlock or Washout" (Season 8, Episode 14). 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 warlocks, or ordinary people.

Content:  Tabitha Stephens (Erin Murphy) (spelled Tabatha in production credits until season 5) is the older child of Samantha and Darrin. She is born in season 2. She has supernatural powers. Tabitha Stephens' birth in the season 2 episode "And Then There Were Three" featured infant Cynthia Black in the role. For the remainder of the season, Tabitha was played by twins Heidi and Laura Gentry, followed by twins Tamar and Julie Young. Fraternal twin toddlers Diane Murphy and Erin Murphy were cast for the role at the beginning of season 3. In time, they began to look less alike, so Diane was dropped during season 4. Diane made several guest appearances in other roles, and filled in as Tabitha one last time in season 5's "Samantha Fights City Hall", because Erin had the mumps. The character was the focus of a spin-off series, Tabitha, initially played by Liberty Williams in the 1976 pilot and by Lisa Hartman in the short-lived 1977 series. Despite airing only five years after the end of the original series, and being set in the 1970s as were the final seasons of Bewitched, Tabitha is depicted as a 20-something college graduate in the spin-off.

In 2002, Bewitched was ranked No. 50 on "TV Guide's 50 Greatest TV Shows of All Time". In 1997, the same magazine ranked the season 2 episode "Divided He Falls" #48 on their list of the "100 Greatest Episodes of All Time".
Title: Elizabeth Montgomery
Content:   In the ABC situation comedy Bewitched, Montgomery played the central role of lovable witch Samantha Stephens, with Dick York (and later with Dick Sargent) as her husband. Starting in the second season of the series, she also played the role of Samantha's mischievous cousin, Serena, under the pseudonym Pandora Spocks (a pun on Pandora's Box). Bewitched became a ratings success (it was, at the time, the highest-rated series ever for the network). The series aired for eight seasons, from 1964 to 1972, and Montgomery received five Emmy and four Golden Globe nominations for her role on Bewitched. Despite low ratings late in the series run, it was renewed for a ninth season to run from fall 1972. However, Montgomery's marriage to Bewitched director William Asher was

(Ironically, Ghostley had appeared in a similar role as Naomi, an incompetent domestic, hired by Darrin to do housecleaning for a pregnant Samantha in the second-season episode "Maid To Order".) In another notable casting change, Louise Tate, played by Irene Vernon during the first two seasons, was played by Kasey Rogers thereafter. The fifth season of Bewitched (1968-1969) proved to be a turning point for the series, most notably with the mid-season departure of Dick York and the record eight episodes which were filmed without him afterwards (although aired out of order with previously

Title: Erin Murphy
Content:  Erin Margaret Murphy (born June 17, 1964) is an American actress, who is best known for her role as young Tabitha Stephens in the television sitcom Bewitched, in 103 episodes from the show's third season (in 1966) to the last original episode in 1972. For the first season, she shared this role for 18 episodes with her fraternal twin sister, Diane, as they were of similar appearance and stature. As they got older and looked less alike, only Erin played the role.
Title: Bewitched
Content:  A beautiful witch named Samantha (Elizabeth Montgomery) meets and marries a mortal named Darrin Stephens (originally Dick York, later Dick Sargent). While Samantha complies with Darrin's wishes to become a normal suburban housewife, her magical family disapproves of the mixed marriage and frequently interferes in the couple's lives. Episodes often begin with Darrin becoming the victim of a spell, the effects of which wreak havoc with mortals such as his boss, clients, parents, and neighbors. By the epilogue, however, Darrin and Samantha most often embrace, having overcome the devious elements that failed to separate them. The witches and their male counterparts, warlocks, are very long-lived; while Samantha appears to be a young woman, many episodes suggest she is actually hundreds of years old. To keep their society secret, witches avoid showing their powers in front of mortals other than Darrin. Nevertheless, the effects of their spells—and Samantha's attempts to hide their supernatural origin from mortals—drive the plot of most episodes. Witches and warlocks usually use physical gestures along with their incantations. To perform magic, Samantha often twitches her nose to create a spell. Special visual effects are accompanied by music to highlight such an action.
