I recently watched the 2014 film Rosewater and recommend it. The film is based on the book Then They Came for Me and dramatizes the experiences of former Newsweek journalist Maziar Bahari who was held captive in Iran for 118 days in 2009 after the presidential elections.
The best aspect of the movie is its vivid concretization of the utter impotence of evil. Bahari’s jailers are explicitly shown to be fearful of him, the truth about the Iranian regime, and the truth about the Western World. They are intimidated by his intellect, constrained by logic, allured by his knowledge of the West, and utterly dependent on his sanction. The movie also concretizes the fact that pain only goes so far and cannot touch the core of certain persons.
