Nazi Concentration Camps (1945)
Director: George Stevens
Runtime: 59 min

The official documentary, made from footage that was recorded by U.S. troops during the liberation of Nazi concentration camps. It was used as evidence at the Nuremberg trials. The camps are shown one after the other, and include footage from Dachau, Buchenwald, Mauthausen and many others. Everyone should see this film, from now until the end of the world, because although we all in principle know that the Nazis committed unimaginable crimes, these crimes are exactly that – unimaginable, because no description and no epithet can adequately convey the feeling of horror that remains in you long after you’ve watched this.
