By analyzing the last scene in Chinatown, we can see how Polanski uses filmic techniques to symbolize the argument against urban sprawl.
When the car approaches the place of destination for the group, we see the city from the perspective of Gittes in the back seat. There are pedestrians, a glowing neon sign flashing “Hong Kong”, traffic on the street, and store fronts advertising their business. Driving through the streets at night, the liveliness of the city is paraded in front of the audience like an exciting carnival ride. The audience is moved through and directly into the center, the heart, of the city at night. It is an experience best felt through the protagonist’s lens and in using a point-of-view shot, this sense of reality is accomplished.
This screen shot shows the use of point-of-view shot. The viewer is placed in Jake Gittes' position through this technique
The close-up shots used during the interaction between Evelyn and her father in this scene call attention to the intimacy that can develop in the city. The conflict between the two interplays ideas of anti-expansion and the American Dream.
The close up shots used here emphasize intimacy and conflict between two opposing forces in the city.
As Evelyn drives off, we see the stark and obvious horizon within the frame that separates the known, bustling city from the unknown, desolate and dark land outside of the city’s limits. That her death occurs right on the horizon is metaphorically connected to Chinatown’s commentary on the city in relation to the suburbs.
Evelyn is murdered as she tries to leave the city, stopped right at the natural boundary that the horizon provides in this frame
The exclusive life-cycle of the city is illustrated in the last shot of the film, as Gittes and his associates walk despondently towards the neon lights leading further into the city. The crowd of curious bystanders engulf the three, and the nondiegetic music connotes fatalism in dark times
The city absorbs Gittes and his associates as dreary music plays outside of the story's world
