12 Angry Men is an undoubted classic film. Beginning with the jury leaving the courtroom to deliberate on the verdict, providing the viewer with no details of the trial itself.
As the jury settle down in their room it is clear that they are all from different backgrounds with differing views on what is right and what is wrong. At the first vote count it is 11-1 in favour of guilty, with only one juror thinking the perpetrator is innocent and begins to question the facts presented to them in the trial.
This is an engrossing film, especially considering that it is filmed almost entirely in the one room and manages to create such atmosphere and tension throughout.
