British actor Paul Bettany becomes Unabomber Ted Kaczynski in the first teaser for Discovery’s new drama series “Manhunt: Unabomber”.

The eight-episode drama sees Bettany don the American terrorist’s trademark grey hoodie in the drama which centres on the FBI’s manhunt for the elusive mastermind behind a 17-year bombing campaign that left three people dead and injured 23 others.

An academic before he became a reclusive criminal, Kaczynski vowed to stop his campaign of terror against universities, airlines and other targets if his 35,000-word manifesto against technology was published. Nicknamed “The Unabomber” by the media based on the FBI’s code name for the then-unidentified suspect, UNABOM (University and Airline Bomber), Kaczynski was eventually captured in 1996 with the help of his brother, David (played by Mark Duplass) and criminal profiler James “Fitz” Fitzgerald (played by Sam Worthington).

The explosive trailer for the limited series teases the frustration behind the years-long search for the self-proclaimed anarchist Kaczynski that was initially begun on an incorrect suspect profile before forensic linguistics expert Fitzgerald urged the FBI to look at the case in a new light.

While the series focuses on the Unabomber, star Bettany told Entertainment Weekly “Manhunt” would not be a sympathetic portrayal of the domestic terrorist.

“The show has no sympathy for Ted Kaczynski, but it does have empathy for him,” Bettany told EW. “That’s important, because otherwise, the conversation stops at ‘monster.'”

“Manhunt: Unabomber” premieres on Discovery Channel Aug. 1.
