: Imagine Dragons was recording their second studio album, Smoke + Mirrors (which features "I'm So Sorry" ), in the exact same studio complex where Hans Zimmer was scoring Kung Fu Panda 3 .
: In the film's official soundtrack, this arranged theme is prominently featured in the track titled The Arrival of Kai .
According to music trivia and community discussions, the crossover happened purely by chance:
The villain in Kung Fu Panda 3 is heavily based on a sample of the rock song "I'm So Sorry" by Imagine Dragons. 🎵 The Musical Connection
: Film composer Hans Zimmer explicitly sampled and rearranged the heavy, driving guitar riff and rhythmic beat of Imagine Dragons' track.
: Zimmer heard the heavy riff they created for "I'm So Sorry" and felt its intense "swagger" was the absolute perfect fit for Kai. The band gladly let him use and adapt the riff for the movie as a thank-you. 🔊 Popular Online Remixes & Edits
