Brian Geraghty is the latest addition to the cast of the crime drama Kockroach, now filming in Australia alongside a high-profile ensemble led by Chris Hemsworth and Taron Egerton. The move gives fresh momentum to a production that adapts William Lashner’s 2007 novel about an outsider’s ruthless ascent through New York’s criminal ranks.
What the casting brings
Director Matt Ross is directing a screenplay by Jonathan Ames, and producers have assembled a wide-ranging cast that includes Zazie Beetz, Alec Baldwin and Rachel Sennott. Geraghty’s addition adds another actor known for gritty, character-driven work, strengthening the film’s dramatic credentials as it moves into principal photography.
The story centers on a mysterious newcomer who climbs the underworld ladder to become a dominant crime figure in New York. Adapted from Lashner’s novel, the project is positioned as a character-focused crime thriller rather than a straightforward action picture.
- Principal cast: Chris Hemsworth, Taron Egerton, Zazie Beetz, Alec Baldwin, Rachel Sennott, Brian Geraghty
- Director & writer: Matt Ross (director), Jonathan Ames (screenplay)
- Source material: Novel by William Lashner (2007)
- Production status: Filming underway in Australia
Geraghty’s recent work and relevance
Brian Geraghty has built a résumé of intense dramatic turns on both screen and stage. Audiences may recognize him from Kathryn Bigelow’s Academy Award-winning film The Hurt Locker, and from his role opposite Denzel Washington in Robert Zemeckis’ Flight. More recently he appeared in Taylor Sheridan’s Paramount+ series 1923 with Harrison Ford and Helen Mirren, and he returned to the stage at the 2025 Williamstown Theatre Festival in Tennessee Williams’ Not About Nightingales.
Those credits underline the kind of presence producers likely sought for a story driven by moral ambiguity and escalating violence — qualities central to Lashner’s novel.
Why filming in Australia matters
Shooting overseas is increasingly common for large-scale productions, often reflecting logistical choices and incentives. For readers, the immediate takeaway is practical: a sizable cast and international shoot typically signal a well-resourced production that could draw attention on awards and festival circuits once completed.
Details about release timing and Geraghty’s specific role in the film have not been announced. Industry observers will be watching for further casting updates and a production schedule as filming continues in Australia.
