The first trailer for Netflix’s Unabomber dropped this week, and it has left even its own star visibly shaken. Jacob Tremblay, who plays the young Ted Kaczynski in the upcoming thriller, admitted he does not like the world the footage reveals - a stark, unsettling portrait of a brilliant mind curdling into something monstrous.
The trailer, released ahead of the film’s September 25, 2026 premiere, offers a grim montage of Kaczynski’s arc: from a gifted Harvard undergraduate to the recluse who terrorized the nation for nearly two decades. Tremblay, best known for his breakout role in Room, says the experience of inhabiting that transformation was darker than he expected. “It’s not a comfortable place to go,” he said in a statement tied to the trailer’s rollout. “You watch it back and you think, this is a real person, and these are real choices, and that’s terrifying.” The actor’s discomfort is the point, according to the film’s creative team, who want audiences to sit with that unease rather than look away.
Directed by Janus Metz, Unabomber chronicles Kaczynski’s life from his early promise as a mathematics prodigy to his eventual descent into domestic terrorism. Between 1978 and 1995, Kaczynski mailed and placed explosive devices across the United States, killing three people and injuring 23 others. The film’s scope is broad, but its emotional core is narrower: it examines how a young man subjected to controversial psychological experiments could later rationalize violence on a national scale. Russell Crowe plays Henry Murray, the Harvard psychologist whose research on stress and personality - funded by the CIA - pushed subjects like Kaczynski to their mental limits. Those sessions, the film suggests, planted seeds that would bloom decades later in a Montana cabin.
Shailene Woodley steps in as Joanne Miller, the FBI agent leading the manhunt that eventually caught Kaczynski in 1996. Her character’s dogged pursuit provides the procedural spine of the story, but the trailer leans harder on the psychological tension between Crowe’s Murray and Tremblay’s Kaczynski. Annabelle Wallis appears as Christiana Morgan, a figure tied to Murray’s inner circle, adding another layer to the academic world that shaped - or warped - Kaczynski’s worldview. The supporting cast includes Alexander Ludwig, Steven Ogg, and Marc Menchaca, though their roles remain under wraps.
What makes the trailer particularly jarring, beyond the grim subject matter, is Tremblay’s physical transformation. The actor, now in his late teens, has been aged up and weathered to suggest a man in his twenties, but the trailer also flashes forward to a grizzled, beard-heavy Kaczynski through makeup effects. Tremblay told reporters he struggled with the duality of the role. “You’re playing someone who was once a normal kid, and then something clicks wrong,” he said. “I keep thinking about the line between ambition and isolation, and how thin it really is.” He added that his own reaction to the finished trailer surprised him. “I didn’t expect to feel so heavy watching it. It’s like seeing a ghost of a person you thought you knew.”
Metz, whose previous work includes the war drama Nightwatch and the documentary Cartel Land, has framed Unabomber as neither a glorification nor a simple true-crime retelling. In production notes accompanying the trailer, he emphasized that the film is less about the bombs than about the intellectual environment that produced Kaczynski’s ideology. The Harvard experiments, which involved intense psychological pressure and verbal abuse, have long been a point of ethical controversy, and the film appears to treat them as a causal thread rather than background color. Crowe’s Murray, in the trailer, delivers lines that feel clinical and cold, suggesting a man who saw his subjects as data points rather than people.
The trailer also leans into the historical texture of the era, from late-1970s campus settings to the primitive cabin where Kaczynski lived without electricity or running water for 25 years. That isolation, the film argues, was both his refuge and his undoing. The FBI’s eventual identification of Kaczynski came through his manifesto, published in newspapers in 1995, which his brother recognized - a detail the trailer hints at but doesn’t fully spoil.
Unabomber carries a TV-MA-style weight in its subject matter, though no runtime has been announced yet. Netflix is positioning the film as a fall prestige play, with the September 2026 release placing it squarely in awards-season territory. Early reactions to the trailer have been mixed but engaged, with some critics praising the performances and others questioning whether another Kaczynski project is necessary given prior documentaries and series coverage. Tremblay, for his part, understands the skepticism but hopes viewers give the film a chance. “I get why people might not want to watch this,” he said. “But the world Kaczynski was reacting to - the technology, the alienation - it’s not that different from ours. That’s what scares me.”
The film’s original language is English, and its production remains rooted in Hollywood’s studio ecosystem despite the Netflix distribution. For Tremblay, the takeaway is personal. “I don’t like the world in that trailer because it’s real,” he said. “And I think we have to look at it anyway.”
