A unique film and music festival,
Klein is conceived as an international festival of short feature, documentary and animated films lasting up to 20 minutes. The festival is an homage to Hugo Klein, a theater professor, theorist and psychiatrist born in Vukovar. It consists of two parts: the competition program consisting of films produced in the previous two years regardless of the category they come from (animated, documentary, feature) and the accompanying film program consisting of representative films made in the earlier period. The film program of the festival contains a total of 15 competition and 35 films of the accompanying program.
