Citywatch, that's an interesting tidbit about the scene in Chinatown.
I guess Polanski thought the audience would be zeroing in on Jack Nicholson's nose and not the surrounding buildings.
Jerry Goldsmith's elegiac score for Chinatown is exquisite.
I can't think of any other score that so captured the mood of a movie (Blade Runner comes close.....for a futuristic Los Angeles).
