Perhaps the most aesthetic end of the world ever shown in a movie. Babies ceased to be born (well, if you dissect the bellies of pregnant women, then everything is logical), some powder remained from food, animals apparently died out, plants mostly became poisonous, the world ocean turned red, Africa went under water. The last youth roam the cities in search of powder and water.
But some of the rest of humanity hears a call inviting them to Athens. The old man-Cinephile Shakespeare and the black boy Cal go there from Bologna, walk this way and find there a group of "last people" from different parts of the world, about a hundred people. These people live in anticipation of death. With the help of a mechanical film camera brought by Cal, cinema appears in the life of the Athenians - they watch retro films, record their daily life on the last film in the world.
All this, of course, is very pretentious - the cradle of European civilization becomes its own grave, and the old woman - the image of European civilization - can no longer give birth. Why would the Athenians think they were the last? Maybe somewhere in Asia, people live in larger groups. Incredible European conceit from the filmmakers.
