The cast of Riverdale recently hit the panel at the Summer Television Critics Association Press tour. That was where CW President Mark Pedowitz and Riverdale show-runner Roberto Aguirre-Sacasa mentioned the series having a spinoff! Can you imagine???
There are no plans as of now about what the show will be about, but there is an idea out there that the storyline could focus on FP, Alice, Hermoine and Fred when they were in high school. That would be super fun!
Whatever it is, I'm so here for it. We probably won't get the spinoff until 2019 - 2020, until then we have Riverdale season 3 to get us through.
