Jeremy Renner returns as Mike McLusky in Season 4 of Mayor of Kingstown, but Edie Falco’s arrival as the new Anchor Bay warden is the casting change most likely to reshape the series. Lennie James also joins as Frank Moses, a respected gangster whose influence reaches beyond Detroit and Michigan.

That premise makes the casting especially important. Falco’s Nina Hobbes represents formal institutional authority inside the prison. James’s Frank Moses brings an established criminal force into a city already struggling to rebalance itself. Meanwhile, Mike, Bunny and the McLusky family must renegotiate their positions in a town where informal arrangements are becoming harder to maintain.
Returning Mayor of Kingstown Season 4 cast
Jeremy Renner as Mike McLusky
Jeremy Renner returns as Mike McLusky, Kingstown’s central power broker. Mike works between gangs, prisoners, guards, police and political interests, attempting to prevent conflicts from becoming open warfare.
Season 4 places that role under unusual pressure. The Russian power structure is gone, competing factions are moving into the resulting vacuum, and Mike’s past continues to affect his ability to control events. Renner remains the anchor of the ensemble as Mike tries to preserve the fragile balance on which Kingstown depends.
Hugh Dillon as Ian Ferguson
Hugh Dillon reprises Ian Ferguson, a Kingstown police detective and Mike’s longtime ally. Dillon is also one of the show’s co-creators and an executive producer, alongside his work in front of the camera.

Taylor Handley returns as Kyle McLusky, Mike’s younger brother and a police lieutenant. Kyle enters Season 4 carrying the consequences of the previous season’s finale, leaving him more exposed to both the prison system and Mike’s efforts to protect the family.
Tobi Bamtefa as Deverin “Bunny” Washington
Tobi Bamtefa returns as Deverin “Bunny” Washington, a gang and drug kingpin. With the Russian power structure no longer shaping the criminal landscape in the same way, Bunny is positioned to become an even more important force in the struggle for control of Kingstown.
Derek Webster as Stevie
Derek Webster reprises Stevie, a detective in the Kingstown Police Department.
Hamish Allan-Headley as Robert Sawyer
Hamish Allan-Headley returns as Robert Sawyer, a police sergeant whose connection to the department and the McLusky family places him within the season’s law-enforcement conflicts.
Nishi Munshi as Tracy McLusky
Nishi Munshi returns as Tracy McLusky, Kyle’s wife. Tracy keeps the family storyline connected to the police and prison conflicts as Kyle faces the fallout from the preceding season.
New principal stars in Season 4
Edie Falco as Nina Hobbes
Edie Falco is the most prominent new addition to the Season 4 cast. She plays Nina Hobbes, the new warden at Anchor Bay Prison.
Hobbes is described as headstrong, and her appointment gives the season a direct institutional counterweight to Mike’s informal authority. Mike may be accustomed to influencing what happens in and around Kingstown, but Nina represents the prison administration’s attempt to assert its own control. Her presence should make the boundaries between official power and Mike’s network more contested.
Lennie James as Frank Moses
Lennie James joins the series as Frank Moses, a respected gangster whose influence extends beyond Detroit and Michigan. Frank gives Season 4 a new criminal power center just as Kingstown’s existing hierarchy is being destabilized.
His arrival is important beyond the size of the role: Frank enters a city where the Russian storyline has left space for ambitious factions to expand. That makes him part of the season’s larger question of who will fill the power vacuum.
Laura Benanti as Cindy Stephens
Laura Benanti plays Cindy Stephens, a new correctional officer. Her character adds another perspective from inside the correctional system, complementing Nina Hobbes’s position at the top of Anchor Bay’s administration.
Additional reported casting
Clayton Cardenas as Deputy Warden Torres
Clayton Cardenas was reported as joining Season 4 as Deputy Warden Torres, described as the incoming warden’s right-hand man. Because the principal Paramount Season 4 cast guide does not list every recurring or guest performer, Torres is best treated as additional reported casting rather than automatically classified as a series regular.

Spoiler context: where Season 3 left the story
Spoilers for the Season 3 finale: Season 3 ended with Mike killing Milo Sunter, Kyle being arrested after shooting Robert, and Iris dying of an overdose after attempting to leave Kingstown. Those events help explain why Mike begins Season 4 with his authority under pressure and why Kyle is vulnerable to danger connected to the prison system.

The Russian storyline also ends as a structural turning point for the show. With that power base collapsed, the conflict is not simply about replacing one criminal group with another. It is about competing factions, Mike’s strained ability to mediate, and the arrival of institutional figures who may not accept his influence.
Where to watch Season 4
Stream Mayor of Kingstown Season 4 on Paramount+. Paramount+ is the official exclusive streaming home identified for the series. Subscription pricing, regional access and promotional offers can change, so viewers should check the service available in their market.
If you prefer physical media, a library catalog records a DVD edition of the series, making Mayor of Kingstown DVD a reasonable search phrase for viewers who want to own the show. That evidence does not confirm a current retailer listing, a complete-series package or a Season 4-specific DVD or Blu-ray release.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why the Season 4 casting matters
The returning cast preserves the show’s central relationships: Mike’s attempts to broker peace, Kyle’s conflict between family and law enforcement, Ian’s alliance with Mike, and Bunny’s place in Kingstown’s criminal ecosystem. The additions change the pressure around those relationships.
- Falco’s Nina Hobbes brings a new formal authority to Anchor Bay Prison.
- James’s Frank Moses expands the criminal contest beyond the established local factions.
- Benanti’s Cindy Stephens adds another correctional-system viewpoint.
- Cardenas’s Deputy Warden Torres gives the new warden an operational ally, although his billing should remain qualified as reported additional casting.
That combination supports a changing-of-the-guard reading of Season 4: Renner’s Mike is still the central figure, but he no longer has the same uncontested room to maneuver.
