In 1973, Claude Lanzmann began work on a documentary about the murder of European Jews during WWII. Twelve years and more than 200 hours of footage later, he finished “Shoah,” a masterpiece widely considered to be the most important Holocaust film ever made. Exploring the French iconoclast’s arduous path to creating his nine-hour-plus masterpiece, CLAUDE LANZMANN: SPECTRES OF THE SHOAH debuts MONDAY, MAY 2 (9:00-9:45 p.m. ET/PT), exclusively on HBO. Academy Award®-nominated in the category of Best Documentary Short Subject this year, the film includes previously unseen outtakes and features the 90-year-old filmmaker’s modern-day reflections on key moments in his life, as well as his hopes for the future.
