Sidney Lumet’s 12 Angry Men is a landmark courtroom drama set almost entirely inside a jury room. As twelve jurors deliberate a murder case, one dissenting voice forces them to confront prejudice, doubt, and the meaning of justice. A tense, dialogue-driven classic, it remains one of the most influential American dramas of all time.
