The cast does a marvelous job of fleshing out the documentary evidence to create convincing characters. Kenneth Branagh is especially chilling as SS Chief of Security Reinhard Heydrich, who uses a combination of charm and ruthless power-mongering to gain support for his plans. Colin Firth is fascinating as Wilhelm Stuckart, a lawyer who sees the brutal tactics of the SS as a threat to his own intellectualized anti-Semitism, and Stanley Tucci gives a wonderfully understated performance as Adolf Eichmann.

Conspiracy is a carefully crafted, completely unsensational film that offers ample proof of the banality of evil. There are no histrionics and no comic-book Nazi villains, just a small group of politicians and war-weary soldiers arguing about the meaning of words and the logistics of extermination, calmly preparing to unleash an unimaginable horror on the world. --Simon Leake
