Titus Welliver has become a household name in crime thrillers thanks to his iconic portrayal of Harry Bosch on Prime Video. Now, as that chapter winds down, he's diving into another high-stakes series: Netflix's The Night Agent. Welliver will appear in the show's fourth and final season, playing a character he describes as anything but ordinary.
In a recent interview, Welliver opened up about his new role, Martin Duval, a Department of Justice special prosecutor. "He has an Ahab-like obsession about obtaining justice after a very, very corrupt previous administration," Welliver explained. "He's been charged with cleanup, and he takes it very seriously." The actor emphasized that Duval isn't a clichéd, charge-ahead type. Instead, he's "very obtuse and very esoteric, but he's the smartest guy in the room." This nuanced take promises to add a fresh layer to the show's final chapter.
Welliver's career has been defined by crime dramas. After headlining Bosch and Bosch: Legacy, he's now starring in the MGM+ series The Westies alongside J.K. Simmons, a show already drawing comparisons to The Sopranos. He's also appeared in classic films like Argo and The Town. For fans of his work, his move to The Night Agent feels like a natural next step.

The Night Agent Season 4 is currently in production and expected to hit Netflix before the end of 2026. Despite a dip in viewership after its explosive first season, the show was renewed for a final run. One major reason for fan excitement is the return of Luciane Buchanan as Rose Larkin, a beloved character who was absent in Season 3. Her comeback in a recurring role has been widely praised as a correction of one of the show's biggest missteps.
Welliver joins an ensemble that includes Gabriel Basso, who plays FBI agent Peter Sutherland. The series, based on Matthew Quirk's novel, has been a staple of Netflix's thriller lineup. With the addition of a character like Martin Duval, the final season promises to delve deeper into political intrigue and moral complexity.
