Netflix Just Added One Of The Best Crime Thrillers Ever Made — And Its 90% Rotten Tomatoes Score Still Holds Up Nearly 20 Years Later
Netflix has added a dark, painstaking crime thriller featuring three actors who would go on to become major names in the Marvel universe — but this is a very different experience from anything involving superheroes.
David Fincher’s Zodiac stars Jake Gyllenhaal, Mark Ruffalo and Robert Downey Jr. in a disturbing exploration of the real-life hunt for the Zodiac Killer, the murderer who terrorized Northern California and taunted police and newspapers with cryptic messages.
Released in 2007, the film remains remarkably well regarded almost two decades later, holding a 90% Tomatometer score from 264 reviews.
And for viewers who only know Downey Jr. as Tony Stark, it offers a glimpse of one of his acclaimed pre-Iron Man performances.
A Killer Who Turned Murder Into A Terrifying Puzzle
Rather than constructing a conventional fictional serial-killer story, Zodiac draws on one of America’s most notorious unsolved criminal cases.
Beginning amid the fear surrounding San Francisco in the late 1960s and 1970s, the film follows the desperate effort to identify the Zodiac Killer.
The murderer didn’t simply attack his victims and disappear.
He sent letters and ciphers to newspapers, creating a mystery that would consume police officers, journalists and amateur investigators trying to establish his identity.
Fincher makes that obsession the centre of his film.
Instead of relying on nonstop action or a steady procession of dramatic confrontations, Zodiac follows the exhausting process of examining evidence, following leads and trying to extract certainty from a case filled with unanswered questions.
The investigation becomes almost as consuming for the people pursuing the killer as the crimes themselves.
Jake Gyllenhaal’s Character Can’t Let The Mystery Go
Jake Gyllenhaal plays Robert Graysmith, a cartoonist at the San Francisco Chronicle who becomes increasingly fascinated by the Zodiac case.
Initially, he is not the obvious person to place at the centre of a major criminal investigation.
But the unanswered questions begin pulling him deeper.
As his fascination grows, solving the Zodiac’s ciphers and establishing the killer’s identity becomes increasingly important to him.
The film gradually turns that search into a study of obsession.
Finding the truth is no longer simply a professional task for the people involved. The case begins intruding into their lives.
That is where Zodiac separates itself from many traditional crime thrillers.
The killer is terrifying, but so is the possibility that the mystery may never provide the definitive ending everyone desperately wants.
Robert Downey Jr. Plays Crime Reporter Paul Avery
Downey Jr. appears as journalist Paul Avery, placing him on the newspaper side of the investigation alongside Graysmith.
It is a performance that came immediately before the actor’s career entered an entirely different era.
Zodiac arrived in 2007.
One year later, Downey Jr. made his debut as Tony Stark in 2008’s Iron Man, launching the role that would make him one of the defining faces of the Marvel Cinematic Universe.
That makes revisiting Zodiac particularly interesting for viewers accustomed to seeing him as the charismatic billionaire superhero.
Here, he is part of a far darker and more grounded story.
And he isn’t the only future MCU star involved.
Mark Ruffalo Is On The Other Side Of The Investigation
Mark Ruffalo plays Inspector David Toschi, one of the investigators attempting to determine who is behind the killings.
Anthony Edwards also appears as an investigator, giving the film both journalistic and law-enforcement perspectives on the mystery.
The ensemble extends considerably further.
Brian Cox and Elias Koteas appear, alongside John Carroll Lynch, Donal Logue, Dermot Mulroney and Philip Baker Hall.
The result is a film populated by people approaching the same mystery from different directions — and gradually discovering just how difficult it is to turn suspicion into certainty.
For Marvel fans, seeing Ruffalo and Downey Jr. sharing the same film before becoming Bruce Banner and Tony Stark adds another layer of interest.
But Zodiac could hardly feel further removed from the MCU.
Why Critics Still Rate It So Highly
The film’s reputation has endured since its release.
Its 90% Rotten Tomatoes score comes from 264 critic reviews, with particular praise directed toward Fincher’s restrained approach.
Rather than focusing primarily on graphic violence, the film spends much of its lengthy running time on conversations, evidence and character detail.
That deliberate pacing is fundamental to the experience.
The audience is made to feel the frustration of chasing a solution that continually seems within reach before becoming uncertain again.
Time Out awarded the film four out of five stars and highlighted Fincher’s exploration of the human need to solve something that may ultimately be unsolvable.
That idea runs through the entire story.
The question isn’t simply who committed the crimes.
It is what happens to people when they cannot stop needing an answer.
A 158-Minute Slow Burn
At 158 minutes, Zodiac doesn’t rush its investigation.
That length allows Fincher to follow the case across years and show how the people involved change as their search continues.
Paramount Pictures describes the film as a true-story thriller built around two forms of obsession: the murderer’s desire to kill and the determination of those pursuing him to uncover the truth.
The latter increasingly becomes the film’s real focus.
Investigators chase leads.
Journalists pursue stories.
Graysmith keeps digging.
And the boundaries between professional responsibility, curiosity and personal obsession become increasingly difficult to separate.
For viewers expecting a fast-moving serial-killer thriller, its methodical approach may come as a surprise.
For those who enjoy detailed investigations and slow-building dread, that is precisely the attraction.
Downey Jr.’s Marvel Return Makes The Timing Interesting
There is another reason Downey Jr. fans may be interested in revisiting his earlier work.
After making his final appearance as Tony Stark in 2019’s Avengers: Endgame, the actor is returning to the MCU in Avengers: Doomsday.
This time, however, he is set to play Doctor Doom rather than Iron Man.
His return makes Zodiac an intriguing reminder of the performances that came before Tony Stark transformed his career.
The film arrived only a year before Iron Man, yet the two roles belong to completely different cinematic worlds.
One Of Fincher’s Most Acclaimed Crime Stories Is Streaming Again
Nearly two decades after its original release, Zodiac has lost little of its ability to unsettle.
There is no need for a fictional mastermind or an elaborate Hollywood conspiracy.
The uncertainty surrounding the real case provides enough tension on its own.
Fincher takes that uncertainty and builds a 158-minute story about people who become unable to look away from an apparently unsolvable puzzle.
Add Gyllenhaal, Ruffalo and Downey Jr. to the investigation, and it is easy to understand why the film continues to be regarded as one of the standout crime thrillers of its era.
For anyone looking for a dark mystery that values atmosphere, painstaking investigation and obsession over easy answers, Netflix has just added a formidable option.
Zodiac is now available on Netflix in regions where the film is offered.
