A K-Pop Movie Starring Rebel Wilson and Charles Melton Is Coming Soon

So far, only Wilson and Melton have been confirmed to star in the film, but on July 1, the Korean entertainment website Star News reported there may be a real-life K-pop idol in talks to join the cast soon: Astro's Cha Eun-woo. According to a translation by Soompi, the star was offered the leading role, and he "even cleared part of his schedule for the second half of 2022 in order to prepare for filming."

No other celebrities have been attached to the project just yet, but the film's director, JK Youn, told Variety in an August 2021 interview that fans should expect K-pop stars, as well as "icons in the pop industry," to appear in the film.
