‘The Westies’ Release Date, Plot, Cast and Everything We Know About J.K. Simmons’ New Irish Mob Drama

Crime drama enthusiasts have a new series to mark on their calendars, and it features an Oscar-winning actor leading the charge. ‘The Westies’ is scheduled to debut on MGM+ on July 12, 2026, reintroducing the infamous Irish American gang from Hell’s Kitchen into popular culture.

This eight-episode crime drama follows a young Irish gangster as he navigates loyalty, organized crime, and the shifting power dynamics of a rapidly evolving New York City. With a cast filled with recognizable faces and a showrunner renowned for high-quality crime storytelling, ‘The Westies’ is poised to become one of the season’s most anticipated new series.

‘The Westies’ premieres on Sunday, July 12, at 9/8c on MGM+. The launch will feature a special two-episode event, with subsequent episodes airing weekly thereafter.

The first season of ‘The Westies’ will consist of eight episodes, with new installments released every Sunday night. The season finale is set to air on August 23, providing viewers with a full summer of intrigue from Hell’s Kitchen.

The series can be accessed directly through MGM+ or via providers like DIRECTV that offer the network. For fans yearning for their weekly dose of high-quality gangster television since the last golden age series concluded, this release schedule promises a steady rhythm rather than a binge-watch experience.

‘The Westies’ boasts a star-studded cast including J.K. Simmons, Titus Welliver, Tom Brittney, Stanley Morgan, Sarah Bolger, Jessica Frances Dukes, Hamish Allan-Headley, Vincent Walsh, Allen Leech, and Hilary McCormack. Simmons stars as Eamon Sweeney, while Welliver portrays Glenn Keenan.

Simmons’s character, Eamon, is depicted as the leader of the Westies, characterized by his charm and loyalty to his crew, yet he is also deeply ruthless. Welliver plays an NYPD officer who grew up around the gang and finds himself torn between his duties and his son, who has taken a destructive path.

Tom Brittney co-stars as James ‘Jimmy’ Roarke, a fiercely loyal and street-smart leader of the younger Westies, who is mentored by Eamon Sweeney. Stanley Morgan plays Mickey Flanagan, the impulsive troublemaker recently released from Bellevue, while Sarah Bolger takes on the role of Bridget Walsh, a steely IRA operative and Jimmy’s girlfriend.

Jessica Frances Dukes completes the main cast as Birdie Polk, the Special Agent in Charge of the FBI’s Gambino Task Force, determined to dismantle both Irish and Italian organized crime. Hamish Allan-Headley appears as a younger version of the real-life mob boss John Gotti, adding historical depth to the ensemble.

Set in the Reagan era of Manhattan, when yuppies dominated Wall Street and Hell’s Kitchen was still years away from its first Starbucks, ‘The Westies’ focuses on the construction of the Jacob Javits Convention Center within the gang’s territory. This project promises a financial boon for the Irish American gang, even as they face overwhelming odds against the Five Families of the Italian mafia.

The legendary brutality and cunning of the Westies have afforded them the leverage to negotiate a fragile peace with the Italian mob, yet internal strife between the brash younger generation and the old guard threatens to unravel everything.

Co-creator Chris Brancato shared insights with Deadline regarding the season’s central conflict, noting that the internal divisions arose as the younger Westies opted to engage in cocaine trafficking, a lucrative but risky venture in the 80s, while the older members feared it could lead to arrests or betrayals.

Brancato also mentioned that the Westies’ conflict with John Gotti and the Gambino crime family, then led by Paul Castellano, serves as a recurring subplot throughout the season. The narrative unfolds in 1980s Hell’s Kitchen, following two childhood friends who choose divergent paths—one becomes a police officer while the other joins the Westies.

The production team behind the series has a proven track record in crime dramas. Executive produced by showrunner Chris Brancato alongside Michael Panes, this marks Brancato’s third collaboration with MGM+. His previous projects with the network include the critically acclaimed ‘Godfather of Harlem,’ featuring Forest Whitaker, and the crime thriller ‘Hotel Cocaine,’ starring Danny Pino.

Brancato is also known for creating Netflix’s hit series ‘Narcos,’ which starred Pedro Pascal and Wagner Moura. This impressive pedigree has drawn the attention of fans of high-quality crime storytelling, especially with early comparisons already surfacing online.

For those missing shows like ‘MobLand’ or ‘Peaky Blinders,’ ‘The Westies’ promises to deliver grit, humor, and unexpected twists. Filming commenced in Hamilton and Toronto, Ontario, in July 2025, providing a suitably gritty backdrop for its New York narrative.

While some names have been altered for the series, much of ‘The Westies’ is based on real events featuring composite characters, tracing back to a gang once known as the Arsenal Gang that evolved into the Westies in the 60s. This blend of dramatized fiction and authentic Hell’s Kitchen history seems to be a key factor in the buzz surrounding the show ahead of its premiere.

With J.K. Simmons leading the cast and a creative team behind some of television’s most celebrated crime sagas, ‘The Westies’ is entering a competitive genre with confidence. As Eamon Sweeney, Jimmy Roarke, and the rest of the gang prepare to hit screens, which side of the Westies’ internal conflict are you rooting for as premiere night approaches?
