In an interview with IndieWire, Aronofsky detailed a few of the distinctive behind-the-scenes approaches Mansell took in an effort to emotionally strike audiences. He acknowledged:
“It’s an excellent rating, truly, a few of Clint’s beats, as an example, are samples from Bruce Lee punches, stolen from films and mainly, become beats. For the third act, for that driving music which climaxes the movie, we sampled from the best Requiems of all time, Mozart, Verdi, and put them right into a drum machine and programmed them and gave that to the Kronos Quartet they usually performed over it.”
Utilizing samples from Bruce Lee’s punches is brilliantly apt. Mansell’s “Requiem” rating is a myriad of musical components with strings, viola, cello, hip-hop beats, and a splash of techno. This mixture of musical genres is paying homage to Lee’s Jeet Kune Do, a hybrid martial arts philosophy that is been credited for paving the way in which for blended martial arts (MMA). By combining numerous kinds, a inventive sound is produced in an effort to seize the multi-faceted monster that addiction really is.
