Deconstruction of London to Brighton teaser trailer

The London to Brighton teaser trailer starts off with a slow, melodic non diegetic soundtrack that mirrors against the diegesis of the three main characters of the film discussing the details of a young girls life and how she has come to live on the streets. This is immediately identifiable as a social realism piece focused on homelessness and prostitution, Joanne is an 11 year old girl who has been hired to perform sexual acts with an older male.  The trailer highlights the issues of child prostitution and as the piano track builds tension against the on screen diegetic discussions, it makes way for a much faster, techno beat non-diegesis that is coupled with a faster pace of editing as we see shots of Kelly and Joanne on the run from the police and the Pimps. This trailer is able to make the audience sympathise with the young girl and the female prostitute whilst being repelled by the acts of the male leads in the piece. The fast paced non diegetic track alongside the sounds of the girls screaming/crying builds a very high rate of suspense and makes the piece gritty and real. By naming famous places i.e.: Brighton the audience are encouraged to realise that the violence and criminal acts happen all around them and are not an isolated incident as it covers England from London to Brighton.  The teaser trailer ends with the off screen diegetic sound of a shotgun blast against a black screen with white title logo.
