The line of fire tv show 2026 cast is led by Peter Krause and Hope Davis, with Kat Cunning, Tommy O’Brien, Taylor Bloom and Charlie Barnett joining the new NBC crime drama. The series premiered on September 21, 2026, at 10 p.m. ET on NBC and is also available for next-day streaming on Peacock.
Created by Joshua Safran, Line of Fire centers on the Hollingsworth family, whose members work across different federal law enforcement agencies. Their professional lives become increasingly complicated when a seemingly straightforward case develops into a larger conspiracy.
The show’s cast combines established television performers with newer faces. Peter Krause leads the ensemble as Secret Service agent Mike Hollingsworth, while Hope Davis plays his wife, Jane Hollingsworth, a U.S. Marshal.
Their three children also work in federal government roles. Kat Cunning plays Clare, Tommy O’Brien portrays Mike “Micah” Hollingsworth Jr., and Taylor Bloom plays Russ.
Charlie Barnett rounds out the principal cast as Jack. The series also features notable guest appearances from Sam Waterston, Campbell Scott and Chris Chalk.
Who Is in the Line of Fire TV Show 2026 Cast?
The main cast of NBC’s Line of Fire includes:
| Actor | Character | Role |
|---|---|---|
| Peter Krause | Mike Hollingsworth | Secret Service agent |
| Hope Davis | Jane Hollingsworth | U.S. Marshal |
| Kat Cunning | Clare Hollingsworth | FBI agent |
| Tommy O’Brien | Mike “Micah” Hollingsworth Jr. | Secret Service agent |
| Taylor Bloom | Russ Hollingsworth | Department of Justice analyst |
| Charlie Barnett | Jack | Member of the main ensemble |
The show also has several guest stars with important connections to the story.
Sam Waterston plays former President Thomas Barnes. Campbell Scott appears as Senator Terry, while Chris Chalk plays current President Kayana.
The combination gives Line of Fire a cast that spans the Hollingsworth family and the political and law enforcement worlds surrounding them.
Peter Krause as Mike Hollingsworth
Peter Krause plays Mike Hollingsworth, a Secret Service agent and the central male character in the Hollingsworth family.
Mike has spent his career protecting important government figures. His work places him inside situations where personal relationships and professional responsibilities can collide.
Krause brings extensive television experience to the role.
U.S. audiences may recognize him from Six Feet Under, Parenthood and 9-1-1. His role as Bobby Nash on 9-1-1 made him particularly familiar to viewers of network television.
Line of Fire marks his return to a leading network television role following his departure from 9-1-1.
The new character is very different from Bobby Nash. Instead of working as a firefighter, Krause now plays a federal law enforcement officer whose job revolves around protection and national security.
Mike also has to manage his responsibilities at home.
His wife and children work in government positions themselves, creating a family where professional information can become extremely sensitive.
That setup gives Krause’s character an unusual challenge. The people closest to him understand the world he works in, but professional rules can prevent family members from openly sharing everything they know.
Hope Davis as Jane Hollingsworth
Hope Davis plays Jane Hollingsworth, Mike’s wife and a U.S. Marshal.
Jane is also the mother of the Hollingsworth family’s three children.
Her career places her in another part of the federal law enforcement system, giving the family several different perspectives on government work.
Davis has appeared in films and television productions including About Schmidt, American Splendor, Captain America: Civil War, Succession, Your Honor and Perry Mason.
In Line of Fire, she takes on a character who has to balance her responsibilities as a federal officer with her role within a complicated family.
Jane’s professional experience also becomes important as the larger mystery develops.
Her relationship with Mike provides another layer to the story because both characters understand the risks involved in government service.
The family does not simply discuss their jobs around the dinner table. Their professional duties can directly affect their personal relationships.
Kat Cunning as Clare Hollingsworth
Kat Cunning plays Clare Hollingsworth, one of Mike and Jane’s children.
Clare works for the FBI, giving the family representation inside another major federal law enforcement agency.
Her position is different from her father’s Secret Service role and her mother’s work with the U.S. Marshals.
That difference becomes important because each family member approaches investigations from a different professional perspective.
Clare is presented as an ambitious member of the family who has built her own career within federal law enforcement.
Cunning’s role adds another young perspective to the Hollingsworth family.
Her character also demonstrates how deeply government service runs through the family. Mike and Jane’s professional lives have influenced their children, who have followed different paths within the federal system.
Tommy O’Brien as Mike “Micah” Hollingsworth Jr.
Tommy O’Brien plays Mike “Micah” Hollingsworth Jr., another of the Hollingsworth children.
Micah followed his father into the Secret Service.
That makes him the family member whose career most directly mirrors Mike’s.
The connection creates opportunities for the series to explore how professional expectations can move from one generation to another.
Micah is not simply working in the same general field as his father. He has entered the same federal agency.
That shared professional background can create both understanding and tension between the two characters.
O’Brien is part of the core young ensemble and appears alongside Krause, Davis, Cunning and Bloom.
Taylor Bloom as Russ Hollingsworth
Taylor Bloom plays Russ Hollingsworth, the third Hollingsworth child.
Russ works as an analyst for the Department of Justice.
Unlike his siblings, Russ does not work directly in the FBI or Secret Service.
His Department of Justice position gives him a different connection to the federal system and adds another professional perspective to the family.
Russ’s role demonstrates the range of government careers represented within the Hollingsworth household.
The three children work in separate areas, while their parents have careers in the U.S. Marshals Service and Secret Service.
That arrangement is central to the show’s family-driven premise.
Charlie Barnett as Jack
Charlie Barnett plays Jack, another important member of the Line of Fire ensemble.
Unlike the Hollingsworth family members, Jack is not one of the three children working in federal law enforcement.
Barnett is known for roles in productions including Chicago Fire.
His casting gives the series another familiar face for television viewers.
Jack’s presence also provides a character outside the immediate Hollingsworth family, helping the story move beyond the family’s government careers.
The character is part of the show’s principal ensemble rather than simply appearing as a one-time guest.
Sam Waterston as Former President Thomas Barnes
One of the most recognizable guest stars in the series is Sam Waterston.
The veteran actor plays former President Thomas Barnes.
Barnes has an important connection to Mike Hollingsworth because Mike previously served on his Secret Service detail.
The relationship between the two characters extends beyond a standard professional connection.
Mike remains affected by a close call connected to his time protecting Barnes, giving their history additional significance within the story.
Waterston’s casting is notable because it brings him back to NBC following his long run as Jack McCoy on Law & Order.
He left Law & Order in 2024 after playing McCoy for many years.
His appearance in Line of Fire therefore marks a return to NBC in a very different role.
Instead of playing a prosecutor, Waterston now portrays a former president with a personal connection to the show’s lead character.
Chris Chalk as President Kayana
Chris Chalk appears as President Kayana, the current president in the world of Line of Fire.
The character is described as strong and decisive while dealing with political concerns and the pressures surrounding his administration.
Chalk has built a television résumé that includes roles in Perry Mason, The Newsroom and other major productions.
His appearance adds another political dimension to the series.
Because Mike works for the Secret Service, the presence of a sitting president naturally connects the family’s professional world to the highest level of federal government.
The character also helps broaden the series beyond investigations involving individual suspects.
Campbell Scott as Senator Terry
Campbell Scott plays Terry, a U.S. senator.
The character is also connected to Jane Hollingsworth on a personal level because Terry is Jane’s boyfriend.
That relationship creates another personal connection within the government setting.
Jane already has a demanding career as a U.S. Marshal and a family to manage. Her relationship with a senator adds another complication to her personal life.
Scott has appeared in numerous films and television productions throughout his career.
His addition to Line of Fire gives the series another established actor in a recurring political role.
How the Cast Fits the Story
The casting structure is central to what makes Line of Fire different from a standard crime procedural.
The Hollingsworth family does not work in one agency.
Instead, its members represent several parts of the federal government.
The family includes:
- Secret Service personnel
- A U.S. Marshal
- An FBI agent
- A Department of Justice analyst
That arrangement creates a natural intersection between different government responsibilities.
A case that begins in one agency can quickly affect another family member.
Personal relationships can also complicate professional decisions.
The show’s central mystery forces the characters to deal with those boundaries while trying to protect one another.
The Hollingsworth Family at the Center of the Series
Mike and Jane sit at the center of the family.
Their three children have followed different paths into federal service.
Clare works for the FBI.
Micah works with the Secret Service.
Russ works for the Department of Justice.
The family therefore has access to different areas of the federal system.
That professional diversity becomes important when a routine investigation develops into something much larger.
Instead of keeping their work and home lives completely separate, the characters find themselves dealing with situations where the two worlds overlap.
The result is a story built around both law enforcement and family relationships.
Why Peter Krause and Hope Davis Lead the Series
Krause and Davis provide the central adult pairing.
Mike and Jane have both built careers in federal law enforcement, but their jobs do not define every part of their relationship.
Their children have also chosen careers connected to government service.
That makes the family unusually familiar with the risks of public service.
At the same time, professional boundaries can create problems.
A parent may know information that a child cannot receive. One sibling may be investigating something connected to another sibling’s agency.
The premise allows the cast to explore those conflicts while the larger conspiracy develops.
Joshua Safran Created the Series
Joshua Safran created Line of Fire and serves as its showrunner.
His previous television work includes Gossip Girl and Quantico.
The series was developed as a family-centered law enforcement drama rather than a straightforward weekly police procedural.
Safran’s approach places the professional lives of the characters alongside their personal relationships.
The story follows federal agents while also examining how their work affects the family around them.
Jenna Bush Hager serves as an executive producer alongside Safran and Ben Spector. Universal Television produces the series.
Jenna Bush Hager’s Connection to the Series
Jenna Bush Hager is another important name behind Line of Fire.
The former first daughter grew up around the Secret Service because of her family’s presidential connections.
That experience helped inform the show’s interest in the personal side of protective service work.
The series explores what happens when people whose careers involve protecting public officials must also manage relationships and responsibilities at home.
Bush Hager’s involvement adds a personal perspective to that part of the premise.
She serves as an executive producer rather than appearing as one of the show’s fictional characters.
When Did Line of Fire Premiere?
Line of Fire premiered on Monday, September 21, 2026, on NBC.
The series airs at 10 p.m. ET on Monday nights.
Viewers can also watch new episodes on Peacock after their NBC broadcast.
The premiere introduced the Hollingsworth family and established the central mystery involving federal law enforcement and a dangerous conspiracy.
The show entered NBC’s fall schedule as a new original drama rather than a continuation of an existing franchise.
That makes its ensemble especially important to the series’ identity.

Its combination of crime, family drama, federal investigations and political intrigue places it firmly in the network thriller category.
