The series is based on the new comic book The Chilling Adventures of Sabrina, which reimagines 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.
In December, concept art for the Sabrina series was released, seemingly plucked right out of its twisted comic book basis.
Sinclair will play series regular Rosalind Walker, the brash, empowered and outspoken daughter of Greendale’s minister and Sabrina’s (Shipka) best friend at Baxter High.
Riverdale showrunner Roberto Aguirre-Sacasa is writing the adaptation of his comic book series and will also executive produce.
