Editing- The director uses a lot of montages to convey the rapid nature of scenes. We see this with a lot of camera cuts and short scenes. The more emotional scenes use long takes for example when the baby dies.
Sound- The music used in trainspotting is usually played really loud to convey the chaos and draws the attention of the viewer and sometimes it is hard to hear the characters. For example when they show the montage of the guys having sex with the girls from the club.
Mis en Scene- The Mise en scene of the movie uses a lot of old and beat up looking props to reflect the time and the setting of a poor area in scotland. The lighting is mostly reflective of the scene so for example when the characters are depressed it has dark and gritty lighting.
