The Edukators - Hans Weingartner (2004)
German film based on the story of three people in their 20s working in dead end jobs who decide to attack the rich establishment. They do this by breaking into their houses and moving around all their furniture, but not stealing anything.
Really fantastic movie, makes you think about anti-capitalism and basically the human spirit. It should be easy to get hold of online, can get it for like £3 in Fopp.
