Shoah (1985) [Documentary]

Shoah is a nine-hour film completed by Claude Lanzmann in 1985 about the Holocaust (or Shoah). Though Shoah is conventionally classified as a documentary film, director Lanzmann considers it to fall outside of that genre, as, unlike most historical documentaries, the film does not feature reenactments or historical footage; instead it consists of interviews with people who were involved in various ways in the Holocaust, and visits to different places they discuss.
