The TVI Take
David Fincher's procedural about the actual decade-plus hunt for the Zodiac killer, structured around the men who became consumed by the investigation rather than the killer himself. Robert Graysmith (Gyllenhaal), Paul Avery (Robert Downey Jr.), and Detective Toschi (Ruffalo) each lose pieces of themselves to a case that resists resolution.
Harris Savides shot on early digital; James Vanderbilt's script tracks the documented evidence meticulously. The film's argument is that some investigations destroy the investigator before they yield the answer.
