1001 Movies You Must See Before You Die is a very reliable reference book featuring some good choices, and I saw this film both for that reason, and because of the length. This documentary from director Claude Lanzmann focuses on the horrific events during the Holocaust, where over six million Jewish people were exterminated. He interviews all the people that are still alive during this time in the Second World War who witnessed parts of if not all of it, including traumatised survivors, people living near the death camps, and very controversially, ex-Nazis who only agreed to be heard but are secretly filmed. We see these people speaking the director's language of French, but there is also some German and Polish language amongst, and some translated on the spot by the director's translator, but don't worry, there is some English too. We see all the locations of death camps and train lines leading to them, e.g. Auschwitz, Chelmno, as they look in the present (sometimes covered in snow, but no matter). What makes this documentary really interesting besides the stories of the people interviewed, is the fact that not one single frame of archive footage (if any exists) is used to portray the horror of these times. At about nine and a half hours long, you may struggle to keep our eyes open throughout the entire thing, but at the same time, you want to hear about these unimaginably horrific incidents. If if it wasn't so long I may give it a slightly higher rating, but don't worry, I don't deny the critics are right to give it five stars, the director did take a decade to complete his film, so it is a must see documentary. It won the BAFTAs for the Flaherty Documentary Award and the Flaherty Documentary Award (TV). Very good!
