12 Angry Men (1957)
There is plenty here to suggest that the accused isn’t guilty but the Lumet’s film is a classic because there is doubt. Technically, the film is perfect with every camera move, line and actor precisely aligned and it succeeds in it’s intention by refusing to resort to sentiment. A lesser film would have justice being done by arriving at the correct verdict, 12 Angry Men has the conviction to arrive at the one the law demands.
