The sing-along version of Netflix’s K‑Pop Demon Hunters will be officially released on the streaming platform on Monday, following the resounding success of the film’s theatre screenings over the weekend.

The sing-along version of the Netflix film topped the box office this weekend, grossing an estimated $18 million to $20 million.

David A. Gross, who runs the movie consulting firm FranchiseRe, calls it “a completely unique two-day musical event.”
