Sometimes conventional wisdom is mktrue: there has been no greater original screenplay in the last 50 years than the one Robert Towne wrote for Chinatown. None more elegantly plotted and politically charged, none more literate and historically evocative, none more pungent in its hard-bitten dialogue and sophisticated in its play on noir archetypes. It’s never easy for a writer to get credit over a director – especially a director as skilled as Roman Polanski at peak form – but Towne’s voice reverberates strongly through a film that perfectly intersects Old Hollywood glamor with New Hollywood revisionism. It’s one of the decade’s true benchmarks.
