Every move those KPop Demon Hunters girls make in Netflix's new dance video came from three real women in a dance studio, and one of them is the choreographer behind routines for BLACKPINK and TWICE. Her name is Leejung Lee. She and two other dancers, Bambi and Nara, performed the whole "How It's Done" routine start to finish, and then Netflix's animators turned them into Rumi, Mira and Zoey. Lee did the motion capture for Rumi in the original movie too. She's said she's usually wiped out after running a routine about twice, and that working on HUNTR/X was a blast because the characters never run out of energy. And most of this dance was never actually in the movie. The camera kept spinning, somebody was always fighting a demon, and the edit cut away before you could catch more than a few seconds of it. Netflix waited 16 months after the film came out to finally show you the whole thing. Netflix is borrowing straight from how K-pop companies run their groups. Look at how the video is shot, with one camera that never moves, a wood floor, gear cases pushed up against the wall, the group's logo behind them and everybody in sweats. Real K-pop labels put out a video exactly like that with most new releases, and they do it so fans will learn the dance, film themselves doing it, and post it. Every one of those copycat videos is free advertising for the song. Netflix needs that more than most. KPop Demon Hunters is the most-watched movie Netflix has ever had, with 482 million views in its first six months, and the sequel isn't due until 2029, in theaters. A normal studio would go quiet for three years and pour everything into a trailer. A K-pop label would never leave fans sitting around with nothing to do for that long, so Netflix is acting like one. You can see the schedule once you start looking. "How It's Done" got its own single release in January, and the "Golden" lyric video has passed a billion views on YouTube. This week Netflix is dropping practice videos for five songs, and episodes breaking down the signature poses start November 2. A cartoon group also gets to skip the thing that breaks up real ones. In Korea, idol contracts top out at seven years under the standard contract rules, which is why so many groups lose members or call it quits right around year seven. Riot just ran that play with K/DA, its League of Legends girl group, which came back this month after six years with two of its four singers swapped out and the same four characters on screen that fans have loved since 2018. I was a producer on Fortnite when we put Travis Scott inside the game, and 12.3 million people logged on at the same time to watch a giant animated version of him perform. People will show up for a cartoon all day long as long as there's a real person underneath it. The movie won't be back until 2029, and Netflix has figured out how to keep its girl group busy for every one of those years.
