Is ‘The Westies’ Based on a True Story? Discover the Real Irish Mob Behind MGM Plus’s Crime Drama

Crime dramas set in the gritty, overlooked corners of American history have become a staple of prestige television, and MGM Plus has established a strong reputation in this genre. The network’s collaborations with showrunner Chris Brancato, known for ‘Narcos,’ ‘Godfather of Harlem,’ and ‘Hotel Cocaine,’ have consistently drawn from real criminal underworlds for their narratives rather than fabricating them.

His latest endeavor, ‘The Westies,’ follows this trend, immersing viewers in 1980s Hell’s Kitchen, where a small yet fierce Irish American gang battles to maintain its territory against the much larger Italian mafia. With J.K. Simmons and Titus Welliver leading an impressive cast, the show has sparked significant interest ahead of its premiere, along with a pressing question.

The answer is affirmative; ‘The Westies’ is indeed grounded in true events. The gang portrayed in the series was real, operating out of Hell’s Kitchen from the 1960s to the mid-1980s, and their notorious reputation for extreme violence, despite their limited numbers, is accurately depicted.

Historical records indicate that the real Westies never exceeded a few dozen members at any time, yet law enforcement connected them to numerous murders committed between the late 1960s and mid-1980s. Their small size necessitated an alliance with the much larger Gambino crime family, mirroring the uneasy relationship shown between the Irish gang and their Italian rivals.

The series draws its central conflict between the old guard and the new directly from the history of the real Westies. In reality, longtime boss Mickey Spillane was ultimately ousted and killed in 1977 in a hit linked to his ambitious rival Jimmy Coonan, who then took over the gang and strengthened its ties with the Gambino family under Paul Castellano.

This real power struggle clearly influences the show’s main dynamic between Eamon Sweeney, portrayed by Simmons as the gang’s seasoned leader, and Jimmy Roarke, played by Tom Brittney as the head of its younger, more reckless faction. While both Sweeney and Roarke are fictional characters rather than direct representations of Spillane and Coonan, the generational conflict they embody is unmistakably intentional.

The show’s plot device involving the construction of the Jacob Javits Convention Center also has historical roots, as the real Westies were heavily involved in union racketeering linked to significant New York construction and cultural projects during that time, including a well-documented scheme that siphoned funds from the Intrepid Sea, Air and Space Museum. Their eventual downfall was hastened by financial investigations into that scheme, which helped dismantle their operation from within.

The gang’s collapse was further fueled by one of their own, enforcer Mickey Featherstone, who turned government informant after a murder conviction he believed was orchestrated by his own crew. His cooperation enabled federal prosecutors to build a sweeping RICO case that imprisoned Coonan for decades, and the show’s inclusion of an FBI task force investigating the gang throughout the season draws directly from this real prosecutorial pressure.

Brancato has described the project as a passion project centered around themes of ambition, loyalty, and power set against the backdrop of 1980s New York, sentiments he expressed in comments reported by TVInsider. This framing aligns with how closely the show adheres to its historical inspiration, even while creating its central characters rather than depicting the real gang’s leaders by name.
