Geraghty's team is spinning this as a major career win—a chance for the respected character actor to shine alongside A-listers in a project with serious pedigree. Matt Ross directing, Jonathan Ames writing? That's prestige territory.
Sources say Geraghty has been strategically building toward something like this. His recent run at Williamstown Theatre Festival in 'Not About Nightingales' alongside Chris Messina and William Jackson Harper wasn't just art—it was networking. The 1923 gig put him back on people's radars.
Geraghty appeared most recently in Taylor Sheridan's Paramount+ series 1923, opposite Harrison Ford and Helen Mirren. He completed a run at the 2025 Williamstown Theatre Festival in Tennessee Williams' 'Not About Nightingales.' Film credits include The Hurt Locker (Kathryn Bigelow) and Flight (Robert Zemeckis).
Geraghty's quietly been putting in the work—now he's reaping the rewards with his biggest cast yet. Watch this one closely.
Brian Geraghty just leveled up, and honestly? It's about time. Deadline reports exclusively that Geraghty has joined the ensemble of Matt Ross' crime thriller Kockroach, which is currently shooting in Australia.
This isn't a supporting player cameo, folks—this is a legitimate role in what looks to be a star-studded affair. The film already features Chris Hemsworth, Taron Egerton, Zazie Beetz, Alec Baldwin, and Rachel Sennott, making Kockroach one of the more intriguing ensembles assembling Down Under this year. The project adapts William Lashner's novel of the same name, following a mysterious outsider who claws his way through New York's criminal underworld to become a powerful crime boss.
Ross is directing from a screenplay by Jonathan Ames—yes, the Bored to Death creator—so you can expect the dark humor and gritty character work that made both men’s previous projects so compelling. For Geraghty, this casting represents something of a career milestone. The actor has built a reputation as reliable supporting talent in serious dramas—The Hurt Locker, Flight—but landing alongside Hemsworth and Egerton?
That's a different tier entirely. His representation at Gersh Agency and Anonymous Content clearly knows what they're doing. Geraghty was most recently seen in Taylor Sheridan's Paramount+ series 1923, appearing opposite Harrison Ford and Helen Mirren.
Before that, he completed a run at the 2025 Williamstown Theatre Festival in Tennessee Williams' Not About Nightingales alongside Chris Messina and William Jackson Harper—solid stage credentials for an actor not typically associated with theater. Additional film credits include Extremely Wicked, Shockingly Evil and Vile opposite Zac Efron and John Malkovich, Elias Daughdrill's Faith, and The Luckiest Man in America starring Walton Goggins and Paul Walter Hauser. The question now is whether Geraghty gets to play enforcer, rival, or something more complicated in Kockroach's New York underworld.
Given the source material's protagonist—a man who rises from nothing through cunning and violence—there's plenty of room for interesting characters around him. With this cast, Ross is clearly building a world worth watching. Production details remain under wraps, but filming happening in Australia suggests some significant location work or tax incentives at play. Either way, Kockroach is shaping up to be the kind of ensemble crime drama that attracts attention come awards season—if it lands right.
