In Wong Kar-Wai’s 2046 the use of music from other sources, from other films, becomes an additional layer to its multi-layered images and narrative.
By musical cue the film gets into an intimate conversation with other films. The themes, topics, and obsessions of one melt and merge with the other. And one director at the height of his career touches the other who makes his final film.
Time is folded into two. Sound and image crystallise.
