It’s conceivable that a film could be as good as this one. Sidney Lumet directed *12 Angry Men*, which was adapted from Reginald Rose's television play. Henry Fonda and Lee J. Cobb lead the cast. The movie centers on twelve jurors who must decide whether a defendant is guilty or innocent, based on what they can reasonably believe to be true. With the exception of two brief moments at its start and finish, the entire film takes place within the single location of the jury room. The atmosphere is hot, intense, and confining—words that really fit Lumet’s superb depiction of twelve men struggling toward a verdict in the case of a young Puerto Rican man accused of murdering his father. The prosecution's case seems solid; there’s testimony, a weapon, and a reason for the crime, so it looks like he’s headed for execution. Eleven jurors think he did it, but one—Henry Fonda’s juror number 8—won’t cast a guilty vote until all of the evidence has been thoroughly considered. As the others argue with him and tensions rise, juror number 8 encourages them to consider their own biases and dedication to fairness. *12 Angry Men* is an example of skillful directing and editing, featuring equally impressive acting. It's definitely something classic film fans should see. 9/10
