J.K. Simmons Leads MGM+’s The Westies: First Teaser

J.K. Simmons is going full Irish mob boss — accent and all — and the first teaser for MGM+’s The Westies is here to prove it. The clip dropped today, giving viewers their first real look at the network’s upcoming period crime drama set in the grimy, pre-gentrification streets of 1980s Hell’s Kitchen.

Simmons plays Eamon Sweeney, the ruthless head of the real-life Irish-American crime syndicate that terrorized New York City during the Reagan era. It’s a role that leans hard on the actor’s commanding presence — but also asks him to work in a new vocal register that, let’s just say, is going to take some getting used to. The accent is… a choice. A committed one. Whether it lands will likely be a matter of personal tolerance, but nobody can say Simmons isn’t going for it.

Hell’s Kitchen, the Mob, and a Very Expensive Convention Center

The series is set in early 1980s Manhattan — Reagan in the White House, yuppies colonizing Wall Street, and Hell’s Kitchen still a long way from its first Starbucks. The central conflict kicks off when construction begins on the Jacob Javits Convention Center, smack in the middle of Westies territory. That project promises a serious financial windfall for the crew, but nothing stays simple for long.

Despite being outnumbered fifty-to-one by the Five Families of the Italian Mafia, the Westies have survived through sheer brutality and street cunning, carving out a fragile détente with the Gambino crime family. But a growing generational divide — between Sweeney’s old-school leadership and the younger, more reckless members of the gang — threatens to blow the whole thing up. And circling above it all is the FBI’s ever-deepening investigation into organized crime in New York.

Small in number but ruthless in execution, the real Westies were one of the most violent gangs in New York City history. That backstory gives the show a lot to work with.

A Cast Built for This World

Alongside Simmons, Titus Welliver plays Glenn Keenan, an NYPD officer who grew up in Hell’s Kitchen alongside the Westies crew. His divided loyalties — between the men he came up with and the badge he carries — look like one of the show’s most compelling threads.

Tom Brittney plays James “Jimmy” Roarke, the ambitious younger-generation leader who looks to Sweeney as a mentor. Jessica Frances Dukes portrays Birdie Polk, the FBI special agent in charge of the Gambino Task Force — the federal pressure bearing down on everyone in the story.

Stanley Morgan plays Mickey Flanagan, described as “the impulsive troublemaker of the Westies gang who’s just been released from Bellevue” — a guy whose loyalty to his friends consistently outpaces his judgment. And Sarah Bolger takes on Bridget Walsh, a “steely and calculating IRA operative with a troubled past” who happens to be Jimmy Roarke’s girlfriend. The cast rounds out with Allen Leech, Vincent Walsh, Hamish Allan-Headley, and Hilary McCormack.

The Showrunner Who Keeps Finding the Dark Side of America

The creative engine behind The Westies is showrunner Chris Brancato, who co-created the series alongside Michael Panes. This is Brancato’s third swing with MGM+, following Godfather of Harlem — the Forest Whitaker-led drama that became one of the network’s signature shows — and the Danny Pino crime thriller Hotel Cocaine. Before all of that, Brancato created Narcos for Netflix, the Pedro Pascal series that turned the Medellín cartel into prestige television.

“The Westies has been a passion project of mine, and I can’t wait to bring it to life,” Brancato said in a statement. “This is a story about ambition, loyalty, and power, set against the backdrop of 1980s New York. I’m grateful to be working again alongside my collaborator Michael Panes and, most especially, with Michael Wright and the entire MGM+ team.”

The eight-episode series premieres Sunday, July 12 at 9/8c on MGM+. The accent, presumably, premieres with it.
