Between 1978 and 1995, Ted Kaczynski launched a targeted mail-bombing campaign that killed three people and injured 23 others. The decades-long search for him, the man who would become known as the Unabomber, would be the longest and costliest investigation in FBI history.
And though he published a so-called manifesto attempting to explain his grievances with society and the point he intended to make with his acts of terrorism, thereâs one question that, despite the Unabomberâs place alongside O.J. Simpson in the U.S.âs pop-culture-meets-media-circus history, has yet to be raised: Why did he do it?
Thatâs at the center of Discoveryâs new series Manhunt: Unabomber, which jumps through time to depict both the FBIâs search for Kaczynski and also traumatic events that happened to him when he was a teenager that could have put him on the path to the man heâd become.
âI think itâs really hard to untangle how much he was driven by real ideological goals, and how much he was driven by fury at his inability to interact with people,â says Paul Bettany, who adopts an engrossing intensity thatâs at once feral and disturbingly calculated as Kaczynski.
Kacyznskiâs story isnât just an explosive oneâtoo on the nose?âbut a tragic one.
Raised in Evergreen Park, Illinois, Kaczynski was a math prodigyâor, simply put, genius. In the fifth grade his IQ tested at 167, and he was accepted to Harvard University at the age of 16. He became an assistant professor of mathematics at University of California, Berkeley at age 25, making him the youngest appointment ever by the institution.
He resigned abruptly two years later, and, by 1971, had moved to a remote cabin in Lincoln, Montana, where he lived as a recluse for the next two decades and, as we know now, waged a deadly mail-bombing campaign in the name of anarchism. A âmanifestoâ he wrote thatâalong with a tip from his brotherâhelped lead to his arrest claimed he was motivated by an opposition to modern technology and industrialization.

DiscoveryBut Manhunt suggests there was more behind his reign of terror than that. As Bettany says, âItâs a fascinating thesis that Harvard weaponized. And Iâm not saying that there wasnât a damaged, awkward child that went to Harvard already. That he didnât turn up damaged. Itâs a thesis, an idea that Harvard kind of weaponized this creature. Itâs arguable.â
As the series horrifically dramatizes, Kaczynski was the subject of ghastly and ethically questionable psychological experiments conducted by a professor he had considered a mentor, which some analysts posit could have been formative in Kaczynskiâs later-in-life theories and acts of violence.
âThe show tries to practice a sort of radical empathy for all victims, really, and see Ted in the context of all of that,â says Bettany. âNot to express or garner or elicit your sympathy for him, because what he did was monstrous acts of horror that inflicted pain on so many people. But I think it is possible and actually important and edifying to practice empathy for the child who had an IQ of 167, ends up at Harvard University, and is then experimented on for three years by MKUltra and the CIA, who were trying to develop techniques to break Soviet spies.â
Of course, a series with the sole intent of humanizing a terrorist would be crass, at best. The clever narrative trick Manhunt employs is its juggling of Kaczynskiâs past and deconstruction of the case against the Unabomber and attempts to track him down.
The central figure in those scenes is Jim âFitzâ Fitzgerald, played by Avatarâs Sam Worthington. It was years before Fitzâs dogged, unconventional tactics used for cracking the caseâlinguistic forensics analyzing Kaczynskiâs manifesto to prove he was the culpritâwould be taken seriously by the cautious, deliberately by-the-books bureaucracy he was working in.
You wouldnât expect an FBI profilerâs deep-dive into speech quirks to be engaging, but itâs a thrilling and unexpected way of bringing the Unabomberâs story into the booming, if increasingly uninventive, true-crime drama space.
âItâs because we didnât just make CSI: Unabomber,â says Worthington. âYou see the mechanics of what it took to take him down and you see the different facets of that manhunt. But at the heart of it, itâs this weird connection between these two men just wanting to be heard, wanting to be validated.â
And if much of the eight-episode series is so riveting because of the elements you may not be familiar withâfrom a case so prevalent and publicized through the â90s that Worthington even caught wind of it growing up in Perth, Australiaâthen the moments that are instantly recognizable are brief respites from the relentless intensity.
Thereâs the widely circulated (if inaccurate) iconic sketchâgray hooded sweatshirt, aviator sunglassesâthat is an indelible part of American pop-culture history, and gets dramatized here, too. And thereâs also the steely, even-handed public face of the investigation, Attorney General Janet Reno, played by Jane Lynch in Manhunt.
âWhen I took the role, one of the things I was fearful of was that I would wind up looking like Will Ferrell and it would be kind of a joke,â Lynch says, referring to Ferrellâs much-celebrated skewering of Renoâs matter-of-fact and, sure, perhaps passionless press conferences on Saturday Night Live.
But her research refuted that generalization. (Reno passed away last fall, just before shooting began.)
âI discovered this 6-foot-3 woman in the Everglades of Florida who was known for being a straight shooter and smart as heck,â Lynch says. âI watched her physicality. I watched the press conferences she gave where she was always very matter-of-fact, flat, and affected. But then you would see pictures of her where sheâs got her head back laughing, open-mouthed laughter.â

DiscoveryLynch and Reno only play a small role in the series, though a memorable one. But the Emmy-winning actress is happy to cede screen time to this unexpected approach to telling the story we thought we all remembered.
âIf this were an hour and a half movie, it would probably be a thriller,â she says. âBut because itâs eight episodes, he gets to breathe and we get to really dive into who Kaczynski was. He might have been wired to be the Unabomber from the moment he was born, but itâs really food for thought to think what happened to his brain [at Harvard] and was that the result, his sociopathic impulses and his disregard for human life and his deep sense of alienation from those experiments on his brain.â
Itâs even more harrowing to think about the prescient nature of the things Kaczynski was warning about in his manifesto. The means by which he made his point may not resonate, but the way his message was startlingly portendingâwarning about the ways technology would define, corrupt, and eventually threaten the safety of our livesâshould horrify you in new ways.
âWhat the manifesto has to say about our relationship with technology and with society is more true right now than it was when Ted published it,â says Executive Producer Andrew Sodroski. âItâs about our relationship with our smartphones 20 years before a smartphone existed. Itâs about the way technology constrains us and defines our lives, the way that when your phone dings, you answer it.â
âPart of the tragedy of Ted is that the only way he could get people to read what he wrote was by bombing people,â he says. âAnd when you bomb people, people donât take what you have to say seriously.â
