NCIS: Los Angeles is likely finished for good after this Chris O’Donnell update. The NCIS: Los Angeles actor is joining a new procedural as its main lead, which has essentially removed all hope for any possible NCIS: Los Angeles reunion. The NCIS spinoff aired for 14 years on CBS before being canceled in 2023. CBS’ decision to cancel NCIS: Los Angeles was surprising, but there was always hope that the characters might return.
NCIS: Los Angeles ended in a way that allowed for the characters to come back. However, now that Chris O’Donnell will be joining the 9-1-1 franchise, he seems more distanced than ever from his performance as G. Callen in NCIS: Los Angeles. The update is great news for the actor and his fans, but disappointing for NCIS: Los Angeles, which seems to have ended for good with season 14.
Chris O’Donnell Joins 9-1-1: Nashville As Its Main Lead
O’Donnell Will Play A Family Man

Following 9-1-1: Lone Star‘s cancelation, ABC announced their newest show, 9-1-1: Nashville, which will air in the fall of 2025. ABC has also revealed 9-1-1: Nashville‘s newest cast member, Chris O’Donnell, who will play Captain Don Sharpe. According to TVLine, Don is described as “a rugged fire captain and rodeo rider who runs Nashville’s busiest firehouse with his beloved son.” Adding on, TVLine’s source revealed that Don is a “family man, but he has his secrets.” O’Donnell’s newest character seems to be tough but with a soft heart.
While limited details exist about Don and 9-1-1: Nashville so far, it seems as though Don will have significant differences to O’Donnell’s other famous role, G. Callen. Given how iconic Callen became during his appearances on NCIS: Los Angeles, there will likely be some similarities drawn between the characters as Don comes to life and his family issues and secrets start to unravel. However, the premises of the characters are entirely different, and I am excited to see how O’Donnell portrays Don and whether he looks at his NCIS: Los Angeles character for inspiration.
“Given O’Donnell’s experience and expertise in procedurals, there is no doubt he will shine as Captain Don Sharpe.”
Not much has been revealed about the newest 9-1-1 spinoff yet, but its setting in Nashville seems to imply that 9-1-1: Nashville will feature rich southern music, food, and culture. With O’Donnell as the first cast announcement so far, the show appears to be moving toward excellent casting decisions. Given O’Donnell’s experience and expertise in procedurals, there is no doubt he will shine as Captain Don Sharpe and leader of the 9-1-1: Nashville team.
