German movie based on the infamous Stanford Prison Experiment (read more about the experiment here) but this movie takes the experiment much further. Twenty ordinary people are divided into twelve prisoners and eight guards and asked to play these roles for two weeks. The story is centered on one of the prisoners, Tarek Fahd.
The drama is intense as behaviours escalate to the flims climax. Plausible and topical given the prison abuses in Iraq. Worth watching (thanks Jennifer for the recommendation).
