It's Always Sunny in Philadelphia is set to return for Season 18, with a major production update from Rob Mac. The comedy series, a fan favorite, has been renewed through Season 18 by FX, with a release date yet to be announced. This news comes after a massive four-season renewal in 2020, ensuring the show's longevity. With a stellar track record, including Season 15 and 16 with 100% Tomatometer scores, and Season 17 at 84%, the show's success is assured. The filming start window aligns with an early estimate, with Season 17 commencing in early fall 2024 and launching in July 2025. This suggests a potential release for Season 18 later this year. However, the show's future beyond Season 18 remains uncertain, with no renewal for Season 19 yet. The cast, including Charlie Day, Glenn Howerton, and Danny DeVito, continues to captivate audiences, despite concerns about DeVito's age. The show's enduring appeal and the team's dedication to storytelling in Philadelphia make it a must-watch for fans of comedy and television.
