Riverdale has been renewed for a sixth season along with eleven other CW shows.
“Though we’re just a few weeks into the new season, we wanted to get a strategic head start on next season with these early renewals, which allows our production teams to start laying out story arcs and hiring staff, and at the same time, continues to provide us with a strong, stable schedule to build on for next season,” he said. “As The CW’s 2020-2021 season kicks into high gear, we are thrilled creatively with the direction of our first new shows out of the gate, Walker and Superman & Lois, that we wanted to order the additional episodes to complete their first seasons.”
