The Cast: Brian Geraghty as Officer Sean Roman


Brian Geraghty stars as Officer Sean Roman on NBC’s police drama “Chicago P.D.”

Geraghty’s unique combination of intensity and appeal has made him a favorite of auteurs and A-listers alike. While perhaps best known for his role as the tightly-wound bomb specialist in Kathryn Bigelow’s Oscar-winning film “The Hurt Locker,” Geraghty also popped as the co-pilot turned religious zealot in Robert Zemeckis’ much-lauded drama “Flight,” opposite Denzel Washington.

His résumé lists such esteemed and eclectic collaborators as Martin Scorsese, Sam Mendes, McG, Jake Paltrow, Carlos Cuaron, playwright Jessica Goldberg and indie darling Kyle Alvarez.

Last year Geraghty joined the pedigreed cast of Martin Scorsese’s “Boardwalk Empire” as Warren Knox, a rookie FBI agent whose baby face and Midwestern charm mask his true nature as a vicious, unhinged sociopath. He can currently be seen working alongside Liev Schreiber on the second season of Showtime’s drama series “Ray Donovan.”
