Train spotting teaser trailer deconstruction

For our research we looked at many social realism teaser trailors. Here is our deconstruction for trainspotting:
The scene starts with the diegetic sound of the men running across the stones on the train tracks. The camera is positioned on the ground allowing the viewers only to see their feet giving it a sense of mystery. There is then a long shot of them running which shows the viewers that it is an isolated place and that there in no one else around.

The diegetic noise of them laughing makes it seem as if their either happy or being silly. There is a close up shot of the rope tied around his neck, showing that there is no way of getting out of the situation of being tied up on a train track, the fact the man is not worried about this shows that he must be on drugs. 

The diegetic sound of him talking controversially about not smoking because it ‘can seriously damage your health’ and ‘most of all don’t let your mates tie you up on the railway track’ is entertaining for the audience because he is being very controversial. The next shot is a long shop of him tied up on the track and the diegetic sound of the train coming emphasises that there is no one around therefore there is no way out of it, the noise of the train starts to increase, making him shout showing that the train is getting closer and closer therefore he is getting into more danger. The close up of him clenching his face and then the screen going black and non diegetic ‘trashy’ music leaves the viewers wanting to know what happened to him, which therefore achieves its purposes because they will be inclined to watch the film.

Having also watched the trailer it is very different to the teaser trailer, I found that the teaser trailer does not give show the story line in any way, instead it just shows boys being silly and creates a sense of mystery, therefore achieving its purposes.
