It's official. Netflix has found its Sabrina the Teenage Witch and they've made a great choice. Kiernan Shipka, best known as Don Draper's daughter in Mad Men and for her role in Feud: Bette and Joan, has been cast in the lead role of Netflix original series Untitled Sabrina Project, based on the Archie Comics graphic novel The Chilling Adventures of Sabrina.

Shipka will star as the titular heroine Sabrina Spellman. She is an empowered young woman, half-human, half-witch, who is just beginning her dark education as a sorceress, even as she tries to maintain a normal life as a sophomore at Baxter High. Intelligent, compassionate and brave to the point of recklessness, Sabrina is all that stands between us and the forces of darkness that threaten our world. Executive producer Roberto Aguirre-Sacasa said this.

"We're all such huge fans of Kiernan's work that when we started talking about who this new incarnation of Sabrina could be, her name was on everyone's wish list. This is a darker, more macabre version of Sabrina, and we're incredibly excited for people to see Kiernan make this iconic character her own."

Executive producer and Archie Comics CEO Jon Goldwater added.

"I am thrilled that Kiernan is playing Sabrina and have no doubt that she will embody the strength, courage and boldness that has made the character a fan favorite."

Shipka most recently appeared opposite Susan Sarandon and Jessica Lange in the hit event series Feud: Bette and Joan, in which she played B.D., the strong-willed teenage daughter of Bette Davis (Sarandon). She is perhaps best known for playing the role of Sally Draper for seven seasons of the acclaimed Emmy-winning drama series Mad Men, opposite Jon Hamm and January Jones.

Sabrina is coming from Berlanti Productions in association with Warner Bros. Television, the same team responsible for The CW's ArrowVerse and Riverdale. Sabrina was actually set up as a Riverdale spinoff, but its darker tone landed it at Netflix, where the streaming service will be ablate go all in on some of the occult aspects of the show.

They join a team that includes Executive Producers Greg Berlanti, Sarah Schechter (Berlanti Productions), and Jon Goldwater (Archie Comics).

Sabrina is based on the Archie Comics characters. Netflix offers this official synopsis for the drama series.

"Sabrina imagines the origin and adventures of Sabrina the Teenage Witch as a dark coming-of-age story that traffics in horror, the occult and, of course, witchcraft. Tonally in the vein of Rosemary's Baby and The Exorcist, this adaptation finds Sabrina wrestling to reconcile her dual nature, half-witch, half-mortal, while standing against the evil forces that threaten her, her family and the daylight world humans inhabit."

The Untitled Sabrina project comes on the heels of the success of Riverdale, which is also based on characters from Archie Comics. No other cast members or character have been announced at this time. And it isn't known if Riverdale and Sabrina will ever get to have the crossover fans are already dying for. Sabrina will stream exclusively on Netflix.
