Nashville Casts Chris O'Donnell's Son and More, Character Details Revealed

Kilgore has been cast as "Taylor," a firefighter who also happens to be an "incredible singer."

She also starred in the Starz TV series Power Book III: Raising Kanana, and appeared in The Village and Amazing Stories. Kilgore also has a solo album debuting this year.

Provost is reportedly playing "Ryan," another firefighter who's described as a "modern-day cowboy."

Provost also appeared in the movie The Holdovers as well as the TV shows The Sex Lives of College Girls and Insatiable.

Feliz has been cast as "Roxie," described as an "adrenaline junkie and former trauma surgeon." Her casting follows her role in the spinoff backdoor pilot for The Equalizer which didn't end up getting ordered to series. She also appeared in the TV shows Harlem,DMZ, and Fleishman Is in Trouble, as well as the recent feature film Civil War.

McVey rounds out the new additions with his role as "Blue." This will mark the on-screen debut for McVey. His Blue character is described as a "haunted bad boy who is now a firefighter."

It was previously revealed that O'Donell will play Captain Don Sharpe, a veteran firefighter and former rodeo rider. He is also the father of Ryan, played by new casting addition Provost. Capshaw is playing Blythe Sharpe, Don's wife and Ryan's mother.

9-1-1 Gets a New Offshoot

9-1-1: Nashville is set in the same universe as the other 9-1-1 shows. The new series, per the official logline, is a "high-octane procedural about our heroic first responders, as well as their family saga of power and glamour set in one of America’s most diverse and dynamic cities.”

9-1-1 Nashville is being written by Ryan Murphy, Tim Minear, and showrunner Rashad Raisani. All three also serve as executive producers alongside O'Donnell, Brad Falchuk, Brad Buecker, and 9-1-1 star Angela Bassett.

The series is expected to debut during the 2025-26 television broadcast season on ABC, but it does not yet have an official premiere date set at this time.
