After a few weeks of rumors, Netflix has finally confirmed a season one order for ‘Sabrina,’ a spin-off in the Riverdale universe. The series doesn’t have an official title at this time, but Netflix has ordered 20 episodes to get things started.

The untitled Sabrina series will be based on the Archie Comics graphic novel ‘The Chilling Adventures of Sabrina,’ and it will most likely follow the darker tone that the CW series “Riverdale” has set for YA audiences. In the announcement Netflix described the series saying the ‘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 show is being produced as a one-hour drama, which has become the most format for new Netflix series. The Executive Producer and writer of the series will be Roberto Aguirre-Sacasa, with Lee Toland Krieger serving as Executive Producer and Director. Greg Berlanti, Sarah Schechter (Berlanti Productions), and Jon Goldwater (Archie Comics) will also serve as executive producers on the show.

The news comes just a few hours after Netflix confirmed a season 3 order of “Stranger Things,” one of the most popular series to ever debut on Netflix. The favorite cast is expected to return, including Winona Ryder as Joyce Byers, David Harbour as Chief Jim Hopper, Finn Wolfhard as Mike Wheeler, Noah Schnapp as Will Byers, Millie Bobby Brown as 11, Caleb McLaughlin as Lucas Sinclair, Gaten Matarazzo as Dustin Henderson, Cara Buono as Karen Wheeler, Natalia Dyer as Nancy Wheeler, Charlie Heaton as Jonathan Byers, Joe Keery as Steve Harrington, Dacre Montgomery as Billy, and Sadie Sink as Max.

The CW has also renewed “Riverdale” for a second-season, following the show’s big freshman debut. Netflix did not confirm any casting announcements at this time.
