David Fincher is nothing if not an innovator. Like Se7en, Zodiac tells the story of a serial killer on the loose. Immersed in this world are Jake Gyllenhaal as newspaper cartoonist Robert Graysmith, Robert Downey Jr ( above) as his San Francisco Chronicle colleague and Mark Ruffalo as detective David Toschi. Their portrayals bring to life Robert Graysmith’s books about real- life killer, the Zodiac, whose campaign of terror confounded the police and the press. Fincher presents a captivating account of obsession that will stick in your head for days.
