Children Of Men

The opening scene of the film consists of many diegetic sounds that don't interest the characters or the audience. However as the film goes on, the news broadcast awakens the interest of the audience as the news reporter reveals that the "Youngest person on Earth" has been killed. This means that the movie has succeeded in achieving one of its main aims, drawing in the audience.

The central character is clearly shown to us when the camera follows him out of the coffee shop. Also, the director has deliberately made this characters actions different and opposite to those around him. This may give the audience a feel for what type of character he is, he may not be one to follow the crowd and lets life go on when tragedy occurs (a strong personality).

I feel that the shot which establishes the narrative is when the camera is facing the T.V broadcast.
It gives us a an idea to what the movie may be about, and also may be the reason for the explosion outside. Angry fans may have lashed out on the public.
