trainspotting opening:
The beginning of the film throws the audience into an action-packed scene later in the film making the narrative non-linear as someone starts to narrate as a close-up of a character presents to the audience that he is the main character and we are in alignment with him because we first see him and hear his voice and the plot. Renton's narration tends to be a rather sarcastic look at life as
He lists stuff like "choosing life, choosing a career and choosing fixed-interest mortgage repayments," as it seems like Renton denounces what society wants us to live and the audience
knows like Renton is the main character as we have a freeze frame of his name that makes it obvious to the audience that he is the main character.  After having us connected with Renton. In his narration he says "choose your friends" and it cuts to a shot of all the other characters and Renton's friends having a football match, but this scene can be seen somewhat as a chilling reminder of the end scene where he betrays them as he no longer wants to be dragged down by them. We see examples of the characters which personality is  Quickly shown and the audience gets a good idea of what they're like, for example, the next character we see is Sick Boy who demonstrates himself to be a sly character as he trips an opponent and pretends he didn't do it. Seen as being an intimidating character as the slide tackles someone without caring and laughing, the next character shown is Spud who we see is shown to be the unreliable and weak character as he fails to catch the ball and the freeze frame is at a point where his facial expression reinforces this, the final character we see is Tommy and when we see him Renton talks about "rotting away at the end  of it all" All of that foretells Tommy's death later in the film and we see him surrounded that could be foreshadowing how he dies from aids and how he's surrounded by death and nothing can help him. After that we are seeing two scenes spliced together as Renton falls to the ground in both scenes and they cut between the two scenes as he rejects life So we find out he's taking heroin and there's no explanation why he's like that just because he wants a breath of fresh air for films because a character who's doing drugs like heroin would have a tragic back story to explain why he's narrating this Renton because he says he does not have any reason to just do it. The younger audience would enjoy this film as in the media drugs are always demonised and exaggerated to be shown as instantly destructive to life, but the film shows drugs in a realistic way as it shows the effects to drugs but it does not romanticise it either, for example, the death of Tommy shows the dark reality of drugs and his death was caused through the use of used needles. Contracting the Aids virus and murdering a newborn due to neglect.
