Claude Lanzmann spent 12 years creating Shoah (1985), a groundbreaking film that redefined Holocaust representation. 40 years later, filmmaker Guillaume Ribot explores 220 hours of unreleased footage.

Lanzmann’s quest to capture the reality of the Holocaust led him to interview victims, witnesses, and perpetrators from all over the world. Overcoming doubt, setbacks, and false leads, he embarked on an unparalleled journey culminating in a landmark masterpiece, now part of UNESCO’s Memory of the World Register.

Only using Lanzmann’s own words drawn from his memoirs and never-before-seen excerpts, Guillaume Ribot pays homage to one of cinema’s masterpieces and to its director’s relentless pursuit of telling the untold.
