From NCIS to Nashville: A Bold New Chapter
After 14 years on NCIS: Los Angeles, Chris O’Donnell was ready for a complete reinvention. The actor immediately gravitated toward 9-1-1: Nashville when offered the lead role, citing Ryan Murphy’s creative vision as the primary draw. “It was an easy decision,” O’Donnell explained in a recent interview with Decider. Moving from Los Angeles to Nashville provided fresh scenery after experiencing the devastating Palisades wildfires. However, stepping into the world of Murphy’s franchise came with unexpected surprises about the show’s emergency storylines.
O’Donnell admitted he wasn’t deeply familiar with the original 9-1-1 series, meaning the scope of the show’s dramatic scenarios caught him off guard. “I had no idea how insane these emergencies are,” he recalled. When he first read scripts featuring wildly dramatic rescues, he called the showrunner in disbelief, only to learn that these scenarios were often “based in reality.”

Navigating Don Hart’s Complex Family Drama
One of the biggest challenges for O’Donnell was understanding Don Hart’s complicated personal life. The character exists in a love triangle, with his wealthy wife Blythe Hart (played by Jessica Capshaw) and his ex-girlfriend Dixie Bennings (portrayed by country legend LeAnn Rimes) both vying for his attention. Adding depth to the drama, Don has two sons with different mothers: Ryan Hart (Michael Provost) with Blythe, and Blue Bennings (Hunter McVey) with Dixie. “The challenge for me was getting my head around that and the culture and feel in Nashville,” O’Donnell said.
| Character Element | Details |
| Don’s Wife | Blythe Hart (Jessica Capshaw), from a wealthy nashville family |
| Don’s Ex | Dixie Bennings (LeAnn Rimes), mother of Blue, from his past life |
| Older Son | Ryan Hart (Michael Provost), Don’s son with Blythe |
| Younger Son | Blue Bennings (Hunter McVey), Don’s son with Dixie, first acting role |
Building Chemistry With His On-Screen Family
O’Donnell spoke glowingly about his castmates, particularly Hunter McVey, who is making his professional acting debut on the show. “This is literally his first gig,” O’Donnell revealed. McVey discovered the opportunity after sending in an audition tape for a different project. Someone in Ryan Murphy’s office noticed his potential, and he landed the pivotal role of Blue Bennings. “He’s a really smart guy,” O’Donnell said, noting that McVey has been absorbing the industry with impressive maturity. The chemistry between Blue and Taylor Thompson (Hailey Kilgore), a paramedic and aspiring country singer, has generated significant fan enthusiasm, with viewers rooting for the young couple’s relationship.
“Oliver and Ryan were amazing sports. They came into our show with no ego, no special requests, no demands. They were just team players from day one.”

The Crossover That Changed Everything
Last month, 9-1-1: Nashville featured its biggest event yet: a crossover episode bringing Buck and Eddie from the original 9-1-1 series to Music City for the Firefighter Games. Oliver Stark and Ryan Guzman, who have been part of the original series for nine years, came to Nashville without any demands or ego. According to O’Donnell, they filmed the sequences twice due to the complexity and intensity of the action, enduring miserably cold weather. The crossover generated tremendous buzz, introducing 9-1-1‘s devoted fanbase to Nashville’s unique brand of high-stakes firefighting drama.
What Can Season 2 Deliver for Devoted Fans?
With Season 2 officially greenlit, O’Donnell is teasing major narrative revelations. “We are setting up a serious cliffhanger,” he stated. “Now that we have been picked up for second season, it will not disappoint.” The showrunners have reportedly been cooking up even more “amazingly big over-the-top events” to keep viewers engaged. As the 2026-27 TV season approaches and 9-1-1: Nashville prepares for a late September or early October premiere, fans can expect Don Hart’s world to become increasingly chaotic, both at the firehouse and at home. The balance between his current wealthy life with Blythe and his unresolved connection to Dixie promises explosive television ahead.
