(A similar approach to another time period, the 1950s, powered Curtis Hanson's L.A. Confidential, another superior color noir effort.)
One of the reasons "L.A. Confidential'' is so good, why is deserves to be mentioned with "Chinatown," is that it's not just plot and atmosphere.
Critics are already comparing “L.A. Confidential” to movies such as “Chinatown” and “Pulp Fiction.”
It helps that they're working with a gifted cinematographer (Dante Spinotti), a composer with deep roots in this genre (Jerry Goldsmith of "Chinatown") and a great script.
A big critical hit at the last Cannes Film Festival, it has been compared repeatedly to "Chinatown," Roman Polanski's classic 1974 L.A. noir (written by director Hanson's onetime mentor Robert Towne).
A lot of people have been comparing "L.A. Confidential" to "Chinatown," but, aside from the obvious noir detail and the setting (and the great, piano-driven music by "Chinatown" composer Jerry Goldsmith), the only thing the two movies really have in common is that absolutely nothing about the crime is what it initially seems to be.
