Based on the Archie Comics graphic novel The Chilling Adventures of Sabrina, Netflix’s Untitled Sabrina Project is set to be an hour-long drama that will reimagine the story of Sabrina the Teenage Witch as a dark coming-of-age tale that traffics in horror, the occult and witchcraft. Twenty episodes have been ordered across two seasons.

Kiernan Shipka (“Mad Men”) was recently cast as Sabrina Spellman, a new take on the character originally played by Melissa Joan Hart. And via Tracking Board today, Jaz Sinclair (Paper Towns) has just joined Shipka in the series.

Sinclair will play the role of Rosalind. Brash, empowered, and outspoken, Rosalind Walker is the daughter of Greendale’s minister and Sabrina’s best friend at Baxter High.

“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 series’ Sabrina is described as follows…

“An empowered young woman, half-human, half-witch, Sabrina 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.”

Roberto Aguirre-Sacasa executive produces and writes. Lee Toland Krieger will executive produce and direct. Other executive producers include Greg Berlanti, Sarah Schechter (Berlanti Productions) and Jon Goldwater (Archie Comics).
