‘9-1-1’ Star Seemingly Spoils a Crossover Major Event Ahead Season 9

We’re just two months away from the premiere of 9-1-1 Season 9, but this is no ordinary premiere. This Fall marks the first time in several years that two shows in the 9-1-1 universe will be on the air at the same time. Additionally, the flagship series and the new spin-off, 9-1-1: Nashville, will air back-to-back. Never has there been a better opportunity for two shows to stage a crossover event. And according to a recent Instagram story by series star Oliver Stark, one might be happening. The actor posted a video of himself in Nashville, where the new offshoot has been filming for the past several weeks. While Stark did not give any clues as to what he was doing there, the coincidence is too big, leading one to think a crossover is on the horizon. At the very least, it could be his character’s cameo.

Could Stark’s previous proposal for his character and Station 113’s boss be coming true? “I feel like Buck would have a lot of fun in Nashville,” he told Screen Rant when the idea of a possible crossover was floated in April 2025. “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,” he added. Stark has been pretty open to crossovers with other shows in the Ryan Murphy-verse. “I would love that. Dr. Odyssey didn’t quite work out, so ship me off to Nashville, and I’ll be there,” he concluded, referencing the now-cancelled medical drama in which Angela Bassett guest starred. Stark being in Nashville is interesting now.

If Buck guest stars at any point in the new show, that would make him the first character to appear in all three 9-1-1 shows, including 9-1-1: Lone Star. The question of crossovers came up during a conversation between Deadline and Craig Erwich, President of Disney Television Group. “They have a really special event planned for 9-1-1: Nashville, and although we haven’t discussed [crossovers], I think it’s an incredible opportunity that I’m sure at some point we’ll figure out how to capitalize on,” was all he shared about the potential for crossovers.

While nothing is confirmed yet, we could be looking at a crossover if Stark’s Instagram story is a good indicator. Stay tuned to Collider for more updates when they develop. The 9-1-1 universe returns on October 9.
