"Tango" by Zbigniew Rybczyński, a 1980 avant-garde film, was the first Polish film to win an Oscar. During the 8-minute film, a room that starts out empty gradually fills with more and more people. Each person repeatedly performs an action on a loop; a boy climbs in and out of the window to fetch a ball, someone does a handstand on a table, a woman paces back and forth with a crying baby, and so on. It seems that everyone is focused on their own actions, with no awareness of anyone else in the room. This causes a brilliant scene of chaos.
The film includes sex and nudity, so it is 'for adult intellectuals only.'"
