Die Welle (The Wave) (2008)

Based on a real-life experiment that took place in a Californian high school, The Wave tells the story of a high school teacher's unusual class experiment. In an attempt to demonstrate what life is like under a dictatorship, the teacher comes up with an experiment to explain to his students how totalitarian governments work. A role-playing game with tragic results. Within a few days, what began with harmless notions like discipline and community builds into a real movement: The Wave. As the students boundaries are pushed, things begin to spiral out of control and this newly found cult starts to take on a life of its own.
