“KPop Demon Hunters” fever is gripping New York, with the stars of the wildly popular animated Netflix film lighting up the Empire State Building on Friday. The movie, which premiered on Netflix in June, quickly became a blockbuster hit around the world, with the streaming giant now releasing a sing-along version in Big Apple theaters this weekend.

The Netflix production KPop Demon Hunters is being showcased in theaters for a limited weekend, featuring sing-along sessions. In a delightful surprise for fans in New York City, the voice actors of the beloved characters took to a double-decker bus to perform several of the songs.

KPop Demon Hunters is a phenomenon that's only growing. The Netflix release focuses on a trio of K-pop idols called HUNTR/X who not only lay down devastatingly catching songs but also battle deadly demons, including the dastardly alluring boy band called Saja Boys.
