Hedgehog in the Fog

“Hedgehog in the Fog” (Ёжик в тумане) is a 1975 short film by animation master Yuri Norstein, and is well worth checking out (this version has English subtitles):

A bit of trivia: “Norstein’s crew consisted of only three people, counting himself, but Soyuzmultfilm imposed the same deadline on his film as they did for productions involving ten times as many people. When the deadline came and ‘Hedgehog’ was only one fifth complete, the director of the studio was enraged and sent Norstein to a Communist Party meeting to be reprimaded for disgracing the studio. One of Norstein’s crew arrived early with a bottle of vodka, convinced the projectionist to screen the footage that they had made, and the committee were so impressed they agreed to let Norstein finish the film.”
