Between decadence, excess, and unbridled creativity, the film follows the intersecting fates of several characters portrayed by Margot Robbie, Brad Pitt, and Diego Calva, helpless witnesses to the talking picture revolution that would forever change their lives. Chazelle delivers a monumental and electrifying fresco, a true love letter to cinema and its capacity for perpetual reinvention.

Justin Hurwitz's score is the vibrant soul of this work. Blending frenzied jazz, majestic orchestrations, and syncopated rhythms inspired by the roaring twenties, the successful composer (La La Land, First Man) delivers here one of his most ambitious and dizzying creations. His music embraces Chazelle's visual frenzy, shifting from the unbridled euphoria of Hollywood parties to the intimate drama of characters consumed by their dreams.
