In 1982 there was a massacre in Palestinian refugee camps Sabra and Shatila in Beirut, Lebanon. Movie 'Waltz with Bashir' depicts this nightmare from a very interesting point of view. It was the lead theme of my visit to Beirut and this picture is a tribute to the aforementioned animation. I walked the whole city, just to find exactly this spot. The place, where Ari Folman is bathing at night by the seaside in Beirut after (or before) the massacre.
I strongly recommend watching this movie.
