The beloved sitcom It's Always Sunny in Philadelphia is gearing up for its highly anticipated 18th season, and fans are buzzing with excitement! But here's where it gets intriguing: the show's future hangs in the balance, with a major production update from Rob Mac (formerly Rob McElhenney) leaving fans wondering what's next.
Published on February 11, 2026, ScreenRant's article by Hannah Gearan, a seasoned film enthusiast, delves into the latest developments. Gearan's passion for cinema began at a young age, and her academic background in film, environmental studies, and writing from Wesleyan University has equipped her with a unique perspective. Her short film, Toxic Faucets, has even made waves at various film festivals, including the prestigious Independent Film Festival of Boston.
The article reveals that Mac, one of the show's co-creators, has shared a photo of a film slate on Instagram with the caption "Back in the kitchen." This suggests that filming for season 18 has commenced, but the release date remains a mystery. The show's longevity is remarkable, with 17 completed seasons under its belt, and the cast includes comedy heavyweights like Glenn Howerton, Charlie Day, Kaitlin Olson, Danny DeVito, and Mary Elizabeth Ellis.
But here's where it gets controversial: the show's future is a topic of discussion. FX's renewal of the series through season 18 back in 2020 was a significant commitment, spanning four seasons. However, the show's fate beyond that is uncertain. The pressure is on for season 18 to deliver, especially with concerns about Danny DeVito's age (turning 82 this year) and his character Frank Reynolds' longevity.
Despite the uncertainties, the show's recent success is promising. Seasons 15 and 16 achieved perfect 100% Tomatometer scores on Rotten Tomatoes, and season 17 maintained a solid 84%. The filming start window for season 18 is on track, and with the previous season's quick turnaround, fans can hope for a late 2026 release. And this is the part most people miss: the show's creators have hinted at more Philadelphia-based adventures, leaving the door open for future seasons.
As fans eagerly await the new season, the question remains: will It's Always Sunny in Philadelphia continue to shine, or will the sun set on this beloved comedy? Share your thoughts in the comments below!
