See Alexandra Daddario's Brother Matthew Chilling On The Chicago Fire Set After Joining Season 15

Matthew Daddario as Gabe DeLuca in Holiday Touchdown: A Bills Love Story.

Chicago Fire’s 15th season is coming soon to NBC amid the 2026 TV schedule, and there's a lot to look forward to. With the firefighter drama having seen some changes, both with the cast and its creative team, some newbies are joining Firehouse 51. One of those new cast members is Alexandra Daddario’s brother, Matthew, and he’s already hanging with his fellow castmates on set.

It was recently reported by Deadline that the Holiday Touchdown: A Bills Love Story star would join the new season of Chicago Fire as a firefighter candidate. Daddario is the latest addition to the series, following BMF’s Da’Vinchi, who is also playing a firefighter candidate. As of now, exact details regarding Daddario's character have not been shared, but he seems to be fitting in. Da’Vinchi shared a post to Instagram, which included a photo of him, Daddario, and series veteran Brandon Larracuente sitting in front of Truck 81. See that photo and other BTS snippets in the post below:
