Juror number three could arguably be described as the most aggressive of the group as he displays the worst aggressive characteristics. He takes the entire case personally; his acute aggression is not a direct result of the current circumstances but a result of past experiences. In the jury room he becomes emotionally aggressive and unable to clearly separate the past from the present. Aggression causes him to become confused and illogical and blinds him from the possible truth. His own hurts, inadequacies, frustration and feelings of powerlessness are all possible causes of his aggression, so although it has most probably been a prominent feature in his natural personality, circumstances throughout his life have fuelled it. He feels by sentencing this particular man to death he will be obtaining vengeance for his own son and perhaps, sentence to death his own disquiet and pain caused by his estranged son.
As the movie 12 Angry Men is filmed on a closed set, there is a need for a diversity of camera angles. Taking close-up shots of juror number three, his angry demeanour clearly conveys to the audience his aggression and creates a feeling of fear and disturbance. By shooting the angle upwards at times shows that his aggression is a powerful characteristic. Even without the words, the visuals themselves can create a tension almost palpable at times; the use of the medium of film means the dialogue doesn't have to convey all the meaning. .
The external issue of the oppressive weather conveyed in the film also leads to displays of aggressive behaviour in individuals. This causes men who are more naturally aggressive to act on it, in contrast to those who are able to display a more controlled and patient manner. This shows that when people show aggression the cause may be totally unrelated to the current situation and the people they take it out on. In the film the men are all placed in exactly the same situation yet their own past context and natural levels of aggression cause them all too respond differently.
