The Idiots(1998)

Original title: Idioterne

A group of perfectly intelligent young people decide to react to society's cult of aimless, non-creative and non-responsible form intellect by living together in a community of 'idiots'. Their primary activity becomes going out into the world of 'normal' people and pretending to be mentally incompetent. They take advantage of this situation to create anarchy, and, by every possible means, to make those around them miserable.
