Night And Fog contains images that are so intensely jarring, that I found myself thinking it wasn't real. This film only 30 minutes in length (couldn't stomach much more), shows rare footage of the holocaust victims and the concentration camps. Michael Bouquet (who is a holocaust survivor) beautifully narrates this film. It reminds us of the importance of what happened in WWII.
P.S. Truffaut called the best film ever made!
