Mank (Original Music Score) is the score album for David Fincher's 2020 film of the same name, composed by Trent Reznor and Atticus Ross. It was released by The Null Corporation label on December 4, 2020, coinciding with the worldwide release on Netflix. The film marks Fincher's fourth collaboration with Reznor and Ross after the Academy Award-winning score for The Social Network (2010), The Girl with the Dragon Tattoo (2011) and Gone Girl (2014). Both Reznor and Ross used period-authentic instrumentation from the 1930s and 40s, instead of their synth-heavy style. The orchestral sections were performed by each members at their homes, due to the COVID-19 pandemic lockdown.
