Robert Towne, screenwriter of Chinatown, reaches further back into Los Angeles history for this dreamy adaptation of John Fante’s autobiographical novel about his early years as a struggling writer. Set in the Bunker Hill neighborhood during the Depression, it focuses mainly on the hero’s troubled affair with a Mexican waitress, played out as a kind of erotic grudge match between Colin Farrell and Salma Hayek. Towne, who also directed, romanticizes the material yet preserves Fante’s critique of his own anti-Mexican biasan attempt to cover his sensitivity about being Italian-American. The period ambience is wonderful, and the story is even sexier than Personal Best (1982), Towne’s directorial debut. With Eileen Atkins, Idina Menzel, and Donald Sutherland. R, 117 min. (JR)
