Duan Vukotić's "Surogat" (alternately called "The Substitute" or "Ersatz" in English) is a satire on civilization's superficiality and humanity's preference for convenience at every turn. The cartoon features a man who brings a collection of inflatable objects to the beach. Literally everything is a blow-up object.
Part of what this short demonstrates is that animation doesn't have to simply be cute stuff for children. It's merely another form of filmmaking. Indeed, animation is one of the best mediums for holding society's problems and shortcomings up to ridicule. But also, the short shows that a cartoon doesn't need a high budget to be good. You can bet money that Vukotić didn't get to spend as much on this short as, say, Walt Disney spent on his average cartoon. Nonetheless, Vukotić had the talent necessary to make a good cartoon. The former Yugoslavia turned out some impressive cinema (as have its breakaway countries). Here we get a sense of how the Western Bloc's shortcomings were just as prevalent in the communist countries. It definitely deserved its Oscar win for Best Animated Short.
I hope to see more of Duan Vukotić's cartoons.
