It’s Always Sunny in Philadelphia has wrapped its landmark 17th season and is confirmed for an 18th season, with the writers' room expected to open in October 2025, signaling progress toward new episodes. Season 17 featured The Gang engaging in various wild schemes, including a crossover with Abbott Elementary, a slap-fighting competition, and Frank's unexpected relationship development on The Golden Bachelor, which may lead to significant plot changes in Season 18. The main cast, including Charlie Day, Rob McElhenney, Glenn Howerton, Kaitlin Olson, and Danny DeVito, are anticipated to return, with recurring characters like Carol Kane's Sam possibly making a comeback. Over its 17 seasons, the show has maintained its sharp humor and inventive storytelling, with notable episodes such as "The Nightman Cometh" and "Mac Finds His Pride" underscoring its enduring appeal. Season 17 also cleverly parodied other TV shows like The Bear and Succession, demonstrating the series' continued creativity. Fans are encouraged to stay tuned for further updates as the new season takes shape.
