With a title that translates as "Foam Bath," this feature-length animation (1979) by Hungarian painter and filmmaker György Kovásznai reveals a gift for jazzy, kaleidoscopic storytelling. A nervous groom in Budapest tells his fiancee's best friend that he wants to call off the wedding; the story's premise may be relatively simple, but its rendering is elaborate and protean, with a zippy pace that demands close attention and jittery, shape-shifting visuals that can be difficult to track. Often the characters' emotions are externalized—expanding, shrinking, fragmenting, and restyling, sometimes from one shot to the next. The film, with its dense, layered backgrounds and trippy score by János Másik, is a challenge to sit through, which makes it all the more exciting. In Hungarian with subtitles.
