Split Screen
Dividing the frame into two or more images shown at once. The panels compare, overlap or accelerate action that single shots could not hold together.
How this film uses it
The film uses a 'hip-hop montage', a burst of very fast cuts, whenever its characters use drugs, and it uses split screen extensively. The montages show the same routine again and again: the preparation, the use, the high and the need. By repeating it across the characters, Aronofsky argues that Sara's pill addiction and Harry's heroin addiction work in exactly the same way. Only the substance changes.
Where to see it
The drug montages. You see the characters' rituals side by side, so you learn the pattern of addiction before the film shows you where it leads.
