Peter Krause on NBC's Line of Fire and his exit from 9-1-1

New series

Krause headlines Line of Fire as Secret Service patriarch

Line of Fire is billed as an NBC action‑thriller created by Joshua Safran. Peter Krause plays Mike Hollingsworth, a Secret Service agent and the patriarch of a family of law‑enforcement officers. The ensemble includes Hope Davis as Jane, Kat Cunning as Clare (an FBI agent), Tommy O’Brien as Micah (a fellow Secret Service agent) and Taylor Bloom as Russell, a new DOJ analyst; Charlie Barnett guest‑stars as Jack. The premiere finds the Hollingsworths targeted by a trained serial killer, forcing them to rely on their collective expertise and confront private secrets. The show mixes choreography‑style ensemble scenes with single‑camera sequences and features guest turns from Chris Chalk and Sam Waterston.

On‑screen family

Mike Hollingsworth wrestles with duty, retirement and family ties

Krause says Mike reaches a crossroads: trying to tie up loose ends before an intended retirement, only to be pulled back into service when his family becomes implicated in a conspiracy. The actor emphasised the series’ interest in the intersection of professional duty and personal life, noting Mike’s intermittent sense of balance and his tendency to value structure, rules and boundaries. Relationships drive much of the drama: Jane is seen dating Senator Terry Cross (Campbell Scott), Clare and Micah each have fraught dynamics with their father, and Russell’s origins at the DOJ are ambiguous. Krause told The Hollywood Reporter he was drawn to the script’s family element and the tonal mix of suspense and humour.

9‑1‑1 exit

Krause reflects on Bobby Nash’s death and the end of his 9‑1‑1 run

Krause spoke at length about his departure from 9‑1‑1, saying showrunner Tim Minear called to inform him that Bobby Nash would be killed off. He described the series as physically demanding — citing injuries and the strain of wearing fire gear and long hours — but said he loved the cast and the experience. Krause highlighted close friendships, particularly with Kenny Choi, and recalled the family atmosphere on set. Addressing fan speculation that Bobby might still be alive, he acknowledged those theories and said plainly, “He could be! We don’t know. I don’t know. I can’t speak to that.”

Career context

A television career rooted in relationships and long‑running roles

Krause reflected on a TV career that began in 1990 with Carol & Company and included Sports Night, Six Feet Under and Parenthood before his eight seasons on 9‑1‑1. He told THR he’s often drawn to characters who are trying to lead a good life and to stories that explore family and relationships. Krause said his agents, Peter Levine and Jamie Feld, brought Line of Fire to him and that he was persuaded by creator Josh Safran’s story architecture and the show’s balance of seriousness and humour. He also recounted his early work with Carol Burnett and the variety of roles he’s pursued across drama and comedy.
