Titus Welliver To Play NYPD Officer In MGM+ Crime Drama The Westies, Opposite J.K. Simmons

Titus Welliver is returning to law enforcement — and this time, he's going after the mob.

The former Bosch star is joining J.K. Simmons in MGM+'s The Westies, a crime drama centered around the real-life titular Irish-American crime gang in 1980s New York City, our sister site Deadline reports.

More specifically, "The Westies is set in the early 1980s when the construction of the Jacob Javitz Convention Center on the Westies' home turf in Hell's Kitchen promises a financial windfall for the Irish-American organized crime gang," per the show's official logline. "Despite being outnumbered 50-to-1 by the Five Families of the Italian mafia, The Westies' legendary brutality and cunning have given them the leverage necessary to share the spoils through a fragile détente. But internal conflict between the brash younger generation and the old-school leadership threatens to set a match to this powder keg, which will sweep the Westies into the FBI's ever-deepening investigation into the Italian mafia."

Welliver is playing Glenn Keenan, described as a "troubled NYPD officer who grew up with the Westies crew, torn between loyalty to the law and love for his wayward son." He'll appear opposite J.K. Simmons as mob boss Eamon Sweeney.

Chris Brancato serves as showrunner of The Westies, co-creating and executive-producing alongside Michael Panes. Production on the eight-episode season is set to begin in Toronto in July.

Welliver is best known for his 10-season run as Harry Bosch, the titular detective in Bosch and its spinoff Bosch: Legacy. The Legacy series finale dropped April 17, ending Welliver's 10-season run as the police detective from the Michael Connelly novels.
