The popular series 9-1-1 continues to thrive following its transition to ABC, with the eighth season currently airing. The upcoming episode titled “Invisible”is scheduled for Thursday, April 3 at 8 p.m. ET. Notably, the franchise is expanding with a new spinoff, 9-1-1: Nashville, which received a straight-to-series order from the network as reported in February 2025.
In a recent interview with ScreenRant, Oliver Stark, known for his role as Buck, expressed enthusiasm about the possibility of his character interacting with the Nashville spinoff. He playfully suggested that Chris O’Donnell’s character could be Buck’s cousin, creating a compelling reason for Buck to visit Nashville. Although a prior collaboration involving Stark in the upcoming series Doctor Odyssey did not materialize, he remains eager to explore further crossovers within the 9-1-1 universe. Here’s what he had to say:
ScreenRant: 9-1-1 is getting another spinoff. Would you be interested in having Buck go over to Nashville?
Oliver Stark: Yeah, let’s go! I feel like Buck would have a lot of fun in Nashville. I saw they cast Chris O’Donnell, could be Buck’s cousin. I’m putting that out there. I could pay a visit to him in Nashville and find myself stumbling down Broadway. Yeah, I would love that. Dr. Odyssey didn’t quite work out, so ship me off to Nashville, and I’ll be there.
