Netflix's 'Unabomber' Trailer: Jacob Tremblay Transforms Into Ted Kaczynski Alongside Russell Crowe

Netflix Just Dropped the Chilling Trailer for 'Unabomber' — And Jacob Tremblay Is Unrecognizable

Netflix is doubling down on true crime this fall, and its latest bombshell might be the most unsettling yet. The streamer has unveiled the first trailer for Unabomber, a gripping biographical drama premiering on September 25, 2026 — and the internet is already buzzing about Jacob Tremblay's jaw-dropping transformation into a young Ted Kaczynski.

Yes, you read that right. The kid from Room and Wonder is all grown up — and playing one of America's most notorious domestic terrorists.

From Child Star to Domestic Terrorist: Tremblay's Boldest Role Yet

A decade after stealing hearts as a child actor in Room (2015) alongside Brie Larson, Jacob Tremblay is making the boldest career pivot we've seen in years. In Unabomber, he plays Ted Kaczynski's transformation from a 16-year-old Harvard prodigy into the infamous recluse who terrorized America with a mail-bombing campaign spanning nearly two decades.

The trailer teases a dark origin story: Kaczynski subjected to controversial psychological experiments at Harvard by Professor Henry Murray — played by none other than Oscar winner Russell Crowe. Decades later, the manhunt to capture him is led by FBI agent Joanne Miller, portrayed by Shailene Woodley (Big Little Lies, Divergent).

The supporting cast is stacked too, featuring Annabelle Wallis (The Mummy, Peaky Blinders), Alexander Ludwig (Vikings), Steven Ogg (The Walking Dead, Grand Theft Auto V), and Marc Menchaca (Ozark).

Behind the Camera: Janus Metz Takes on America's Darkest Chapter

Directing duties fall to Janus Metz, the Danish filmmaker behind Borg vs McEnroe and episodes of HBO's True Detective — a perfect fit for this brooding material. The screenplay comes from Sam Chalsen and Nelson Greaves, with Sophie Cassidy producing for 2.0 Entertainment in association with MRC.

This isn't Netflix's first rodeo with disturbing true stories. After the massive success of Dahmer – Monster: The Jeffrey Dahmer Story starring Evan Peters, Mindhunter from David Fincher, and this month's chart-topper The Whisper Man with Robert De Niro, Adam Scott, and Michelle Monaghan, the streamer clearly knows its audience craves prestige crime content.

• Title: Unabomber (2026)
• Release date: September 25, 2026 — only on Netflix
• Director: Janus Metz
• Writers: Sam Chalsen and Nelson Greaves
• Stars: Jacob Tremblay, Russell Crowe, Shailene Woodley, Annabelle Wallis, Alexander Ludwig

So, should you add it to your watchlist? If haunting character studies like Theodore-adjacent prestige dramas, Zodiac, or Extremely Wicked, Shockingly Evil and Vile (starring Zac Efron as Ted Bundy) are your thing — absolutely. Tremblay's chilling reinvention alone looks worth the subscription. Mark September 25 on your calendar; this one will dominate the group chat.
