Zodiac (2007)

The Zodiac Killer is one of the most written-about unsolved criminal cases in American history. Active primarily in Northern California between the late 1960s and early 1970s, the killer claimed at least five confirmed victims, taunted police and newspapers with coded letters, and was never officially identified. The case generated an enormous amount of press coverage at the time, much of it centred on the San Francisco Chronicle, and it has since become a fixture of true crime culture. Robert Graysmith, a political cartoonist at the Chronicle who became personally consumed by the investigation, wrote two books on the subject, and it is his account that forms the basis of this film. That source material gives the story an unusual angle: rather than following detectives alone, it places an amateur, a man with no investigative authority and a great deal of stubborn curiosity, at the centre of the narrative.

David Fincher directed Zodiac for Paramount Pictures, Warner Bros. Pictures, and Phoenix Pictures, releasing it in 2007. By that point, Fincher had already established himself as one of Hollywood's more technically precise and tonally controlled filmmakers, with crime and psychological unease running through much of his work. Fans of his output will find much here that feels familiar from his other films, and readers who have seen our reviews of Se7en (1995) and Gone Girl (2014), both directed by Fincher, will have a reasonable sense of what to expect in terms of mood and method. The film runs to 157 minutes, which is a significant commitment, and it was shot by cinematographer Darius Khondji, whose work leans toward shadows and muted, period-appropriate colour palettes that suit the material considerably well.

The cast is one of the more interesting assembled for a film of this type. Jake Gyllenhaal plays Robert Graysmith, and it is worth noting that Gyllenhaal has form with crime material (our review of Prisoners (2013), in which he also stars, is worth a read if you want a point of comparison). Mark Ruffalo plays Inspector David Toschi, the San Francisco detective whose name became almost as well known as the case itself, while Anthony Edwards appears alongside him as his partner. Robert Downey Jr. takes the role of Paul Avery, the Chronicle crime reporter who became a target of the killer's letters, and Chloë Sevigny plays Graysmith's wife. The ensemble is, on paper, polished but varied in register, mixing actors known for restrained character work with others more associated with heightened or mercurial performances. Whether that combination holds together across nearly three hours is, of course, a matter worth getting into properly.

David Fincher’s Zodiac is a masterclass in atmosphere, precision, and creeping dread. Based on the real unsolved case of the Zodiac Killer who terrorised Northern California in the late 60s and 70s, the film trades in procedural detail, obsessive investigation, and the psychological toll of chasing a monster who may never be caught. Uncertainty hums beneath every frame, amplified by Fincher’s cold, controlled direction, Darius Khondji’s shadow-drenched cinematography, and a score that feels like a slow pulse in the dark. The performances are excellent across the board. Jake Gyllenhaal, Robert Downey Jr., and Mark Ruffalo each bring something distinct. Gyllenhaal the quiet obsession, Downey Jr. the chaotic brilliance, Ruffalo the grounded cop-next-door realism. Ruffalo, in particular, stands out with a performance that’s understated but deeply human, a man doing his job while the case slowly consumes him. There’s no showy grandstanding, just commitment to the grind of detective work. Where the film stumbles is in its length and structure. At nearly three hours, it often feels like a series of “this happened, then that happened”, meticulously accurate, yes, but sometimes at the expense of momentum. The middle drags under the weight of ciphers, leads, and dead ends, and while that’s the point (the real investigation was exhausting) it can make the film feel like a marathon rather than a sprint. But that’s also what makes it great. Zodiac isn’t about resolution. It’s about obsession, the cost of truth, and the horror of never knowing. It’s a true crime thriller that refuses to give easy answers, and in doing so, becomes one of the most authentic, haunting entries in the genre.

For me, that question of whether the length is a flaw or a feature is the most interesting thing to sit with after the credits roll. I keep coming back to the idea that a tidier, two-hour version of this film would almost certainly be a lesser one, even if it would be an easier watch. The exhaustion is the point, and Fincher seems fully committed to making you feel it rather than simply telling you about it. I find that kind of formal honesty genuinely rare in mainstream American cinema, and it makes Zodiac a film I respect more each time I think about it, even if it does occasionally test your patience in the moment. Some films earn their runtime. This is one of them.
