12 Angry Men is a 1957 American drama film adapted from a play. Directed by Sidney Lumet, the film tells the story of a jury made up of 12 men as they deliberate the guilt or innocence of a defendant on the basis of reasonable doubt. The film is notable for its almost exclusive use of one set: with the exception of two short scenes at the beginning and the end of the film set on the steps of the court building and two short scenes in an adjoining washroom, the entire movie takes place in the jury room.
