Is it possible to joke about the Holocaust? Filmmaker Ferne Pearlstein tackles that thorny question in this funny and thought-provoking documentary by confronting such famous humorists as Mel Brooks, Carl Reiner, Sarah Silverman, Gilbert Gottfried, Harry Shearer, Judy Gold, Larry Charles and others. These interviews are woven together with a vast selection of clips, ranging from The Producers to "Curb Your Enthusiasm." There's even newly discovered footage of Jerry Lewis' famously unreleased Holocaust comedy The Day The Clown Cried and rare, historic footage of actual cabarets inside concentration camps. 85 minutes Unrated.
