Deconstruction of transpotting teaser trailer

The teaser trailer for Trainspotting features a childish group of boys running down a railway track, revealing that they have tied up one of their friends to the tracks, shortly before the train is due to arrive, "That is, if its not late!". Seen in the trailer, there is a close up shot sequence of the main character (Renton) tied to the tracks and offering advice to the audience (thus breaking the fourth wall), this advice is countered by the narrative of the film and offers a cheeky view on life.  Renton is still laughing as he explains that the most important rule is, "don't let your mates tie you to the railway track!" Trainspotting revolves around how Renton's life is troubled by the social group he is a part of and by tying him to the railway tracks, they have condemned him to his death and allowed him to be run over by the train. This isn't something that would be seen as what a friend would do for you and therefore from the onset of the trailer we know that Renton is different from the others. This difference leads him to be tied up in this situation and then the inevitable happens as the off screen diegetic sound of a train approaching coupled with a POV shot of the train facing Renton makes up the climax of the trailer.

This climax finishes with a black screen with a scrolling title of 'Trainspotting' panning across the screen at high speed, synchronous to the sound of the train. This lets the audience know that Renton has been hit by the train and wasn't saved by his social group. Trainspotting is Danny Boyle's commentary on the lack of social mobility that Scottish working class youths felt in the 90's and this is particularly relevant as Renton can't escape this situation that his friends have got him into.
