Based on true events, Zodiac follows San Francisco Chronicle cartoonist Robert Graysmith as he becomes consumed by his amateur investigation into the notorious Zodiac serial killer. The film spans decades, exploring how the unsolved case affects detectives, journalists, and civilians alike. Director David Fincher crafts a meticulous, atmospheric thriller that prioritizes procedural detail and psychological obsession over conventional horror.
Fincher films the case as documentary procedure. The film refuses identification and respects the open verdict; the genre's most patient entry.
Obsession as journalism: a cartoonist and two reporters chase a killer who is never caught. Fincher makes not-knowing the most haunting ending of all.
Fincher's narrative film is documentary in method: every newsroom call, every cipher, every dead lead. Zodiac was never solved; the film does not lie about that.
