9. Petsch met her ex-boyfriend Travis Mills after the musician also auditioned for the series.
“He messaged me on Facebook in January of season one and congratulated me on the show,” she told Cosmopolitan in 2017. “He had auditioned for Jughead. I think we just randomly had mutual friends, so we added each other.”
10. Before landing her breakout role in Netflix’s 13 Reasons Why, Katherine Langford tested for Betty, with Camila Mendes, who landed the part of Veronica, telling EW, “I remember we went out and we got falafel with a guy who was auditioning for Archie.”
11. It wouldn’t be the show’s only casting loss to 13 Reasons Why as Ross Butler left the show at the end of season one to become a full-time cast member on the Selena Gomez-produced drama. Charles Melton took over the role of Reggie.
12. Years before starring together on Riverdale, Mendes and Sprouse attended NYU at the same time, though he didn’t remember they were classmates.
“Cole always laughs when I tell him that because I remember meeting him on certain occasions and he doesn’t,” Mendes told Office magazine in 2017. “I’m always like, ‘Fine! Whatever! Sorry I’m not a child star!'”
She went on to jokingly call him “a weirdo” during their college years, explaining, “He had really long hair down to his butt cheeks. He was really shy too. I would see him at parties sometimes and I always kind of randomly talked to his brother [Dylan] but I never got a chance to talk to him because he was more to himself.”
