A film about LA and water set in the l930's during a drought with a dark incestuous subplot and some stunning performances by Faye Dunaway and Jack Nicholson, and superb cinematography that seemed to capture the essence of LA. Directed by Roman Polanski, who makes a terrific cameo appearance as a switchblade wielding heavy, and using the considerable acting talents of John Huston as a ruthless and perverted landowner. Read Cadillac Desert to know about LA's water grab but see Chinatown for its brilliant allegory of water and corruption, both public and private. The direction, the screenplay, the acting, the photography, and the soundtrack combine to make a convincing and atmospheric picture. The crushing ending is just so much more icing on the cake.
