EXCLUSIVE: FBI: International alum Luke Kleintank is set as a series regular opposite lead Stephen Fry in Fox‘s upcoming drama series The Interrogator. The project, from Lionsgate Television and Fox Entertainment Studios, has a 12-episode straight-to-series order for the 2026-27 season.

The Interrogator centers on former MI6 agent Conrad Henry (Fry) and his elite team. When conventional methods have failed, Henry’s quirky charm, superior intellect and mind-bending behavioral maneuvers make him the only man able to lockpick the minds of the world’s most dangerous criminals.

Kleintank will play Voss, a member of Conrad Henry’s small circle of analyst/advisors. He’s former Special Forces, an Army whistleblower with a strong moral code. A former Colorado farm boy, he’s quiet, outdoorsy and prefers dogs to people… except for an unlikely clandestine romance with fellow team member Florence that can only stay secret for so long.

The pilot script was written by Fry, with revisions from Matt Pyken as well as William Harper. Dan Dworkin and Jay Beattie are executive producers and showrunners. Fry executive produces alongside William Harper and Paul McGuigan, who will also direct. Likely Story’s Anthony Bregman and Miriam Mintz, Matt Pyken, Neil Burger and Anonymous Content also serve as executive producers on the series.

Kleintank headlined CBS’ FBI: International for its first three seasons as Special Agent Scott Forrester. Prior to that, Kleintank was a series regular on the first three seasons of Prime Video’s The Man In the High Castle. He also recurred on CBS’ Person of Interest and Fox’s Bones. Kleintank is repped by Robert Stein Management, Gersh and attorney Stewart Brookman.
