‘It’s Always Sunny in Philadelphia’ Season 18 Release Date, Time & Preview

The wait is finally over for fans of Paddy’s Pub. ‘It’s Always Sunny in Philadelphia’ Season 18 kicks off tonight, Monday, August 17, at 9 p.m. on FXX, FX, and Hulu, with international streaming available on Disney+.

The timing feels almost poetic, as the premiere date falls on the day fans have eagerly marked on their calendars. The Gang returns for an expanded ten-episode season, a notable increase from the eight episodes of the previous three seasons.

Season 18 signifies a shift in pace for the show, arriving approximately one year after Season 17 concluded, breaking the two-year gaps fans had become accustomed to. This is the first time since Season 14 in 2019 that a new season has debuted just one year after the last.

‘It’s Always Sunny in Philadelphia’ holds the title of the longest-running live-action sitcom in television history, a distinction it has maintained by a significant margin. The show solidified this record when it surpassed ‘The Adventures of Ozzie and Harriet’ in total seasons back in December 2021 and has continued to extend that lead.

The renewal for this season dates back to December 10, 2020, when the show was confirmed for an eighteenth season. Charlie Day later shared on The Today Show that the Season 18 writers’ room would commence work in October 2025, with filming for the new episodes set to begin in February 2026.

The core Gang remains unchanged, with Charlie Day, Glenn Howerton, series creator Rob Mac, Kaitlin Olson, and Danny DeVito all returning to run the struggling dive bar Paddy’s Pub once more. This level of consistency after eighteen seasons is rare in television and contributes significantly to the show’s enduring cult following over the past two decades.

Behind-the-scenes footage from Rob Mac’s docuseries ‘Welcome to Wrexham’ provided fans with an early glimpse of production, showcasing episodes referred to in the footage as ‘2026: A Virtual Insanity,’ ‘The Gang Gets Tested,’ and ‘The Gang Goes to the Ren Faire.’

That same footage reportedly confirmed the return of a recurring character named Luther McDonald, aligning with details that leaked from a script fans had been buzzing about online.

One lingering thread from the Season 17 finale involves Frank proposing marriage to Sam, played by Carol Kane, and it remains uncertain whether Kane will return to resolve that storyline. Given the beloved chemistry between her character and Danny DeVito’s Frank last season, her potential return is one of the more discussed mysteries leading into the premiere.

According to the official synopsis, the Gang becomes embroiled in an inheritance dispute, grapples with workplace automation, dives into conspiracy theories, and even attempts to improve its image by sponsoring a Little League baseball team. This chaotic, timely premise is exactly what the show has built its reputation on for nearly twenty years.

FX has hinted that the new season will delve into themes of inheritances, automation anxiety, conspiracy theories, and society’s evolving relationship with sobriety, all while amplifying the chaos at Paddy’s Pub. FX has also promised some of the series’ most outrageous moments yet, along with a generous dose of star cameos and nods to both Philadelphia culture and classic television comedy.

Fans can still catch up on the previous seventeen seasons on Hulu and Disney+, although five controversial episodes have been permanently removed from circulation due to their use of blackface. This context has followed the show for years, and it is important for new viewers to consider as they explore the back catalog ahead of tonight’s premiere.

The first trailer was released prior to the premiere with the tagline “the only thing generated is more chaos,” referencing a fake AI-generated poster the series had shared earlier in the promotional campaign. This marketing approach is very much in line with a show that has spent eighteen seasons satirizing whatever cultural moment is trending.

Behind the scenes, the season is executive produced by series creator Rob Mac alongside Day, Howerton, Michael Rotenberg, Nicholas Frenkel, David Hornsby, Rob Rosell, Scott Marder, Dave Chernin, John Chernin, and Vanessa McGee, with FX Productions producing the series. This deep bench of longtime collaborators is a major reason the show’s tone has remained consistent, even as television comedy has evolved dramatically since 2005.

With ten new episodes of ‘It’s Always Sunny in Philadelphia’ premiering tonight, the Gang has never had more opportunities to run wild. Fans are already speculating online about which storyline, the inheritance drama or the Little League sponsorship, will spiral out of control first. Which plotline are you most eager to see unfold at Paddy’s Pub?
