The Remarkable Korean Cast and Producers Featuring Stars Behind ‘K-Pop Demon Hunters’

Since its debut on Netflix on June 20, the animated film K-pop Demon Hunters has taken the world by storm, climbing to number one in 41 countries, including South Korea, the U.S., Japan, and Taiwan. The film didn’t just dominate the streaming charts—it also made a major splash on Spotify’s U.S. Daily Top Songs chart with its original soundtrack, showing it’s more than just an animated movie; it’s a full-blown music event.

Songs like “Your Idol,” “Golden,” “How It’s Done,” “Soda Pop,” “What It Sounds Like,” “Free,” and “Takedown” all landed in Spotify’s top 100, with fans highlighting the quality of the music. The track “Takedown” gained special attention because it features a version sung by none other than TWICE, one of the biggest K-pop girl groups out there. Their involvement added an extra buzz and helped draw even more eyes and ears to the film.

Beyond the soundtracks and charts, people have been digging into the talent behind the project, uncovering an incredible lineup of voice actors and producers. Before the film’s release, Ahn Hyo Seop and Lee Byung Hun were already generating buzz, but after seeing the film’s huge success, fans and Korean netizens were surprised by the full star-studded cast revealed behind each character.

Along with Ahn Hyo Seop and Lee Byung Hun, the voice cast includes well-known names like Arden Cho as Rumi, Ken Jeong playing HUNTR/X’s manager Bobby, Daniel Dae Kim as Healer Han, and Kim Yunjin voicing Celine. The ensemble blends top Korean and Korean-American talent, giving the film a strong and diverse presence.

Music production was led by Teddy from 1TYM, who now works as executive producer at THE BLACK LABEL. He brought together a powerhouse production team including 24, Ido, Dominsuk, Jenna Andrews, Kirk, Lindgren, and Ian Eisendrath. This group delivered a killer soundtrack that’s been a big part of the film’s appeal.

The animation’s moves and energy also got a boost from top-tier choreography, thanks to LEEJUNG, who is famous for her work and appearances on Street Woman Fighter. She designed the animated dance sequences, bringing that authentic K-pop precision into the film’s visuals.

The film has drawn a lot of love from Korean netizens, who call it a “collaborative masterpiece” for how it brings together some of the biggest names from across the Korean entertainment field. The excitement online was palpable, with fans leaving comments like:

"Daniel Dae Kim was in it?? Even TWICE only featured the Korean members—I’m getting emotional."
