"Then in Chinatown..., she was the shifty heart of a film, far more so than Jack Nicholson. It is Dunaway who most effectively relates the worlds of the elegant Mrs. Evelyn Mulwray (a woman from a Lubitsch film, condescending to appear in a George Raft picture) and the glowing, mango-colored China doll who sleeps with Nicholson's detective and has an ingrowing family tree. She looks like a cross between Joan Crawford and Sylvia Sidney until she turns her head to the light and her arched brows show the flawed iris nemesis of Chinatown."

(from "The New ... : Expanded and Updated", p. 263)

"The heroine of Chinatown, and in many ways the chief victim of the intrigue, was Evelyn Mulwreay, played by Faye Dunaway... She managed to evoke memories of the great actresses from the 1930s, while adding a very modern feeling of tragedy. The nose? You know the nose."

[I don't know what Thomson meant about "the nose", but I'm including it in case I figure it out later.]
