Why Sabrina was rejected from appearing on Riverdale

Entertainment Weekly

Roberto Aguirre-Sacasa, the showrunner behind The CW's Riverdale and Netflix's Chilling Adventures of Sabrina, says he considered bringing Sabrina to Riverdale as the antagonist and as a potential cliffhanger "before Riverdale exploded and found its footing as sort of a noir, crime, pulp show." Ultimately, he and his team changed their minds. “For various reasons, and I think partly because Riverdale found its footing as more crime show, that felt less and less like the right fit,” he says. “It felt like if Riverdale is crime and pulp and all that stuff, then Sabrina could be horror. It felt like there was a separation between Greendale and Riverdale — magic should exist in Greendale, but not in Riverdale. That was the thought.”
