After 14 seasons as the enigmatic G. Callen on NCIS: Los Angeles, Chris O’Donnell is making a bold—and fitting—career pivot. The actor is set to lead 9-1-1: Nashville as Captain Don Sharpe, a rugged firehouse commander with cowboy grit, family ties, and secrets of his own.
Unlike Callen’s shadowy world of covert ops, Sharpe operates front and center, balancing high-stakes rescues with fatherhood and leadership at Nashville’s busiest firehouse—alongside his son. The role taps into O’Donnell’s strengths while offering a fresh emotional lens grounded in community, legacy, and resilience.
Set against Nashville’s soulful backdrop, the series promises adrenaline-fueled emergencies with heart. For O’Donnell, it’s not a lateral move but a reinvention—one that trades federal intrigue for blue-collar heroism without losing depth.
