The CW series announced it is doing another musical based on an iconic high school film. “Last year, we had a blast doing Carrie," says showrunner Roberto Aguirre-Sacasa of the musical episode, scheduled for March 20. This year, we wanted to honor another iconic teen movie. Heathers: The Musical is BIG FUN, with great roles for the Riverdale kids. And everyone is singing…” This will be the second time in a year that Heathers is being brought to the small screen, following Paramount Network's failed reboot. The musical will feature Veronica Lodge as Heather McNamara, Betty Cooper as Heather Duke and Cheryl Blossom as Heather Chandler. Archie Andrews will also appearing in the musical despite the events of this week's episode.

Riverdale's Heathers musical is the latest failed TV attempt to pay tribute to the 1989 cult classic (https://www.indiewire.com/2019/03/heathers-riverdale-reboot-problems-paramount-anniversary-1202052445/)

Riverdale "didn't even try" with its musical tribute, says Hanh Nguyen, pointing out that it joins last year's Paramount Network TV adaptation of Heathers in failing to successfully bring the 1989 dark comedy film to television. "There’s no real attempt at presenting the Heathers plot at all, and all of the stage show’s songs are performed out of context," Nguyen says of Riverdale's second musical. "This is less of an homage and more of a Frankenstein creation, giving incoherent life to stitched-together elements. This is not an indictment on the quality of Riverdale overall; it knows the pulpy shtick that works for its audience. It just isn’t interested in giving the audience any understanding of Heathers beyond monochromatic outfits and croquet mallets."
