Riverdale — a one-hour drama based on the iconic Archie comic book characters has moved to CW. The subversive take on the well-known franchise’s wholesome town of Riverdale and residents Archie, Betty, Veronica, as well as Josie and the Pussycats, originally was being developed at Fox. Greg Berlanti still is exec producing via Berlanti Productions, in association with Warner Bros TV. Archie Comics’ chief creative officer Roberto Aguirre-Sacasa is writing the pilot. Sarah Schechter and Jon Goldwater also are EPs.
