KPop Demon Hunters has transcended its status as just another animated film, becoming a cultural force that has captured global audiences with its unique mix of K-pop flair, fantasy, and action. Following its roaring success, co-director Maggie Kang shared intriguing details about the film’s early casting process in a July 16 interview with Cosmopolitan Korea. One of the standout revelations was that the role of Gwi Ma, the film’s main antagonist, was originally envisioned for none other than JY Park — the legendary producer and founder of JYP Entertainment.
According to Kang, Gwi Ma was initially conceptualized as a flamboyant and slightly comedic figure — a demon who harbored dreams of becoming a K-pop idol himself. With that early version in mind, JY Park seemed like the perfect fit. Known not only for his legacy in shaping some of K-pop’s biggest acts, but also for his own theatrical performances, eccentric fashion choices, and unfiltered charm, he embodied the exact energy the creative team was looking for at the time. Maggie Kang admitted that the character was practically designed with someone like JY Park in mind during the initial development phase.
However, as production progressed and the tone of the film evolved, so did the direction of Gwi Ma’s character. The writing team and directors re-envisioned the villain not as a satirical figure, but as a darker, more traditional antagonist — someone who exuded menace, mystery, and raw power. This tonal shift called for a drastically different kind of voice — one that could carry the depth and danger the new version of Gwi Ma demanded.
Enter Lee Byung Hun. With a rich history of powerful performances in both Korean and international projects, including Squid Game and I Saw the Devil, he brought the gravitas the film now needed. His deep, authoritative voice lent an unsettling weight to Gwi Ma’s presence on screen, transforming him into a truly formidable villain. Maggie Kang emphasized that once the team heard Lee Byung Hun deliver the lines, they knew he was the right choice — the character came alive in a way they hadn’t imagined before.
In the end, while fans may be amused imagining a version of Gwi Ma brought to life by JY Park’s flamboyance, the choice to cast Lee Byung Hun proved to be a turning point. His performance has been widely praised by critics and audiences alike, with many noting how his voice work added an unexpected layer of sophistication and intensity to the film. It’s a decision that not only aligned with the story’s darker shift but also elevated KPop Demon Hunters into the realm of animated storytelling that doesn’t just entertain — it resonates.
