‘Unabomber’ Recap and Ending Explained: The Real Harvard Experiment That Made a Killer

Netflix has a new true crime thriller on its hands, and viewers are already scrambling for answers once the credits roll. Directed by Janus Metz Pedersen, ‘Unabomber‘ dramatizes the story behind one of the longest and most notorious manhunts in American history, following Ted Kaczynski.

Between 1978 and 1995, Ted used mail bombs to claim three lives and injure 23 others, but the film is far more interested in the years before he became a killer. The drama inspired by true events traces Kaczynski’s path from Harvard prodigy and test subject to the Unabomber as the FBI hunts him down.

What Really Happens in the ‘Unabomber’ Ending

‘Unabomber’ opens with Thomas J Mosser finding a mysterious package in his mail, and opening it triggers a bomb explosion that instantly takes his life. From there, the story splits between two timelines that, as one outlet put it, never quite touch, with Shailene Woodley’s FBI behavioral analyst Joanne Miller convinced in 1995 San Francisco that the bureau is chasing the wrong kind of man.

Meanwhile back in 1958 Harvard, Jacob Tremblay’s teenage Theodore Kaczynski signs up for a debate club run by Russell Crowe’s Professor Henry Murray, believing he has found a mentor. In the present, Joanne hears of a report of someone claiming to know the Unabomber, and her follow up ultimately leads her to Ted Kaczynski, though without hard evidence she is forced to drop the investigation, only for the bomber to strike again just days later.

According to breakdowns of the film, Joanne understood that her colleague David’s rejection of the Kaczynski theory stemmed from emotion rather than evidence, and she paid a personal visit to the family house before embarking on a solo mission to keep chasing the lead. ‘Unabomber’ ultimately ends with Ted Kaczynski leaving Henry Murray’s experiment and taking his first steps on the path that eventually turns him into the infamous bomber.

Ted Kaczynski’s Harvard Years and the Murray Experiment, Explained

In the flashbacks, Ted becomes increasingly obsessed and agitated by the debate exercises, but everything changes when he discovers that Henry and his team have been secretly recording their private conversations to use against him during those very debates. It turns out Henry has been conducting experiments on how to subdue people like Ted, rather than actually help them grow, and feeling betrayed, Ted begins preparing for revenge.

The film grounds this in some uncomfortable history. Writers Greaves and Chalsen started with a foundation of fact, since Ted Kaczynski did attend Harvard starting in the late 1950s, and he did participate in experiments led by real professor Henry Murray. The film even confirms that Murray’s experiment was real, and so was the code name the study gave Kaczynski.

Where things get murkier is the movie’s biggest swing. Whether the experiments were all part of the CIA’s MKUltra program is something argued rather than documented, and the movie takes liberties by presenting its entire premise around that theory. Critics have noted that the film ultimately refuses to give a clean explanation for what made Ted Kaczynski tick, which has fueled plenty of post-watch discourse.

Some breakdowns frame it as an interesting parallel between Joanne and Ted, arguing that both characters realize they live in a faulty world, but while Ted chooses to rebel through violence, Joanne fights it a different way. That thematic doubling is a big reason the ending has people talking well beyond the plot mechanics.

Shailene Woodley’s FBI Investigation Storyline

Director Janus Metz has described Shailene Woodley’s character Joanne Miller as the audience’s entry point into the story, the one who starts asking who the Unabomber really is and what drives him. Her storyline begins with the bureau struggling to identify the killer through their profile after Thomas J Mosser is killed by a mail bomb.

Not every critic is equally sold on this half of the film. One review argued the Harvard portion is the far more intriguing storyline, calling it fresh, while describing the FBI manhunt as typical potboiler thriller material audiences have seen countless times before. That same review admitted Woodley is fine with the material she has to work with, even while confessing her scenes made their interest sag compared to the Kaczynski timeline.

Still, the film isn’t without a genuine surprise for viewers paying close attention. Even a critic who preferred the Harvard storyline admitted a sort of twist near the end of the film landed as a satisfying reveal they did not see coming. Shailene Woodley once again delivers a strong portrayal of an investigator on a mission, according to a review of the film.

The Cast Behind Netflix’s ‘Unabomber’

The film stars Russell Crowe, Jacob Tremblay, and Shailene Woodley in the lead roles. The supporting cast rounds out with Annabelle Wallis, Alexander Ludwig, Steven Ogg, and Marc Menchaca in key roles.

Tremblay has spoken about how seriously he took portraying such a divisive real figure. He explained that he really wanted to make sure he went into the role playing Kaczynski as a real person with real emotions. That approach seems to have shaped the entire back half of the film, where his transformation from student to bomber becomes the emotional core.

The film also has a notable detail waiting for viewers who stay through the end credits, including the voice of the real Ted Kaczynski himself. It’s worth noting the movie was directed by Janus Metz, who previously directed the 2022 film ‘All the Old Knives’ as well as episodes of ‘Andor’ and ‘True Detective.’

With the film’s timelines, its CIA-tinged theory, and that credits scene all fueling conversation, ‘Unabomber’ has clearly left its mark right out of the gate. Do you buy the film’s argument that Henry Murray’s experiments are what truly created the Unabomber, or do you think the movie is letting Ted Kaczynski off too easy?
