Kiernan Shipka, who played Sally Draper on Mad Men, is set to star in her own show. Netflix is rebooting Sabrina the Teenage Witch with Shipka in the starring role. The show is a spinoff of the wildly popular Riverdale, and its creators describe it as quite a departure from the '90s hit staring Melissa Joan Hart. The Netflix adaptation is based of the much darker and creepier Archie Comics graphic novel, The Chilling Adventures Of Sabrina, which explores dark dark magic and the occult. And, of course, Sabrina will still need to get through high school.
