The international title for this Yugoslavian animated film is "Curiosity" and it is told using rather simple animation and a very limited color palate (perhaps it has faded a lot over the years, but most of the colors are very, very subdued and white prevails).
AS guy is sitting on a park bench. He falls asleep now and again as people keep coming up to see what he had in a bag sitting next to him. It's all very silly and overly exaggerated...but also kind of funny because of its absurdity. I am sure that after a while, the audience, too, becomes curious--especially because when people do look inside the sack, they make odd faces--it must be something pretty strange. See the film yourself if you, too are curious.
While the animation is only okay, the idea of showing how stupidly curious we all can be is pretty cute. Not exactly a must-see film, but since it's not at all dependent upon language (using nonsense speech instead of a Slavic or other language), it's a good film for anyone to watch.
