With the help of the US Holocaust Museum's archival team and Claude Lanzmann’s daughter, Angelique, the production was able to explore dozens of hours of unused material filmed for the 1985 documentary “Shoah.” Select reels of that footage was incorporated into the film with the blessing of the Lanzmann family. The film also includes new footage filmed at the camps in Poland, new interviews with survivors and liberators, and original music composed by Golden-globe nominated composer, Benjamin Wallfisch.
The film was created by 19-year-old Indianapolis-based filmmaker Ashton Gleckman, who traveled around the country to interview survivors. He worked with the various memorial sites in Poland to film at the concentration camps and historical sites and went on to edit the film and help to compose the score. The film commemorates the 75th anniversary of the liberation of Auschwitz.
