A Report on the Party and the Guests
O slavnosti a hostech (original)
In Jan Němec’s surreal fable, a picnic is rudely transformed into a lesson in political hierarchy when a handful of mysterious authority figures show up. This allegory about oppression and conformity was banned in its home country but became an international success after it premiered at the New York Film Festival.
