12 Angry Men is a 1957 American courtroom drama film directed by Sidney Lumet, adapted from a 1954 teleplay of the same name by Reginald Rose. The film tells the story of a jury of 12 men as they deliberate the conviction or acquittal of an 18-year old defendant on the basis of reasonable doubt, forcing the jurors to question their morals and values. It stars Henry Fonda (who also produced the film with Reginald Rose), Lee J. Cobb, Ed Begley, E. G. Marshall, and Jack Warden.
The film was selected as the second-best courtroom drama ever (after 1962’s To Kill a Mockingbird) by the American Film Institute for their AFI’s 10 Top 10 list. It is regarded by many as one of the greatest films ever made. In 2007, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being “culturally, historically, or aesthetically significant”.
