NCIS: Los Angeles, starring Chris O’Donnell, Eric Christian Olsen, Daniela Ruah and more, came to an end in 2023 after 14 seasons
Chris O’Donnell Makes Major Post-NCIS Move — Joins Rival Network’s New 9-1-1 Spin-Off
After saying goodbye to NCIS: Los Angeles in 2023 following a remarkable 14-season run, Chris O’Donnell is officially stepping into his next chapter—and it’s a fiery one.
The beloved actor, who portrayed Special Agent Grisha “G.” Callen since the very first episode of the hit CBS procedural, has landed his first major role since wrapping up his work on NCIS: LA. And in a surprising twist, he’s switching gears—and networks—by joining the world of Ryan Murphy’s 9-1-1 franchise.
According to Variety, O’Donnell has been cast as the lead in 9-1-1: Nashville, the latest spin-off in the high-stakes first responder universe. The series is set to premiere during the 2025–26 television season and will be the second offshoot of the wildly popular franchise, following the now-concluded 9-1-1: Lone Star.
🔥 From Special Agent to Fire Captain
O’Donnell will portray Captain Don Sharpe, a rugged firehouse leader and rodeo rider based in Nashville. Described as a devoted husband, loving father, and a respected figure in the city’s busiest firehouse, Sharpe also harbors secrets that promise to bring tension, drama, and intrigue to the series.
This new role marks a bold pivot for the actor—and one that has fans buzzing about what’s to come. With 9-1-1: Nashville, viewers can expect the same explosive rescues, emotional twists, and high-stakes storytelling that made the franchise a primetime staple.
🧯 A New Rival Emerges
The 9-1-1 franchise, created by Murphy, Brad Falchuk, and Tim Minear, originally teased a Las Vegas-based spin-off, but that project was ultimately shelved in favor of Nashville. With O’Donnell now attached, the stakes—and the expectations—are higher than ever.
While 9-1-1: Lone Star ended earlier this year after five seasons, the flagship series continues to thrive in its eighth season on ABC, with stars like Angela Bassett, Peter Krause, and Ryan Guzman delivering pulse-pounding performances.
🚨 Where the NCIS Universe Stands
Meanwhile, the NCIS franchise remains a juggernaut in its own right. The flagship NCIS continues with its 22nd season, led by Sean Murray, Wilmer Valderrama, and Katrina Law. Other spin-offs like NCIS: Sydney and NCIS: Origins are thriving—with the latter offering a compelling look back at the early days of Leroy Jethro Gibbs.
Though NCIS: LA closed its doors in 2023, its stars remain deeply connected to the world of TV. LL Cool J made guest appearances on NCIS: Hawai’i, Daniela Ruah stepped behind the camera to direct within the franchise, and Eric Christian Olsen now serves as executive producer for CBS’s Matlock reboot starring Kathy Bates.
🎬 A Bold New Beginning
Chris O’Donnell’s casting in 9-1-1: Nashville proves that even after nearly two decades of playing one of TV’s most beloved federal agents, there are still new fires to fight—and new stories to tell. With a role that blends grit, family, and mystery, this latest move may just be the most exciting of his career yet.
Stay tuned for more updates as 9-1-1: Nashville gears up for its explosive debut.
