It’s Always Sunny In Philadelphia season 13: plot, cast, trailers, rumours and more

Everything we know so far about the return of the controversial black comedy based around Paddy’s Pub.

The spectacle of a bunch of disparate, self-centred, back-stabbing sociopaths shouting at each other has sustained Big Brother for eighteen series so far. So it’s no wonder that It’s Always Sunny In Philadelphia, the black comedy sitcom following the depraved antics of The Gang running Paddy’s Pub and built on the same solid foundation of laughing at spiteful idiocy, is running The Adventures Of Ozzy And Harriet close for the title of the longest-running live-action sitcom in US history.

As we’ve all no doubt caught up with season 12 in its two months on Netflix, it’s time to look forward to the return of the sitcom equivalent of Reservoir Dogs. Here, with dotted spoilers, is everything we know so far about season 13.

Latest updates:

  • The first full trailer has been released

It’s Always Sunny In Philadelphia season 13: air date

Though the air date was first announced by FX, cast members of Always Sunny tweeted out an illustrated homage to Friday The 13th which revealed the air date of season 13 to be September 5. The image shows Charlie, Mac, Frank and Dee running from an axe-wielding Dennis.


Even before season 12 aired, seasons 13 and 14 (the latter’s commission ensuring that it’ll be one of the longest-running live-action US sitcoms in TV history) had already been confirmed, thanks to its massive global following.

“If anyone doubts the power of a camcorder and a dream, just look at It’s Always Sunny in Philadelphia, which was a DIY backyard pilot when Rob [McElhenney], Charlie [Day] and Glenn [Howerton] brought it to FX and will go down in TV history as one of the most loved and enduring comedies,” said FX’s President of Programming Nick Grad. “Few shows make it this far or have such devoted fans, and we owe it all to the creative vision and great humour of the creators and cast who keep Sunny fresh and inventive every season.”

Back in May, Kaitlin Olson (who plays Dee) revealed that the show was on an extended hiatus after the new season had been pushed back a year to allow for the cast to complete other projects. “At the end of this coming shooting season of The Mick I’ll step right into Sunny after that,” she told TV Guide.

Who is in the Season 13 cast?

It’s not going to (quite) be the whole Gang. Although Danny DeVito is expected to return as Frank Reynolds for the next two seasons at least, Glenn Howerton will be back as Dennis – but only part-time. The final episode of season 12 closed with Dennis declaring he was leaving Philadelphia to “go be a dad” while the rest of the Gang shook their funky butts to the Tom Tom Club.


Howerton will not appear regularly in the forthcoming series due to his commitments with NBC’s A.P. Bio, but he will pop up occasionally as the show explores his life as a dad in North Dakota.

In an interview with Variety (August 3), the cast spoke about the extent that Dennis would be in the show responding to claims of Glenn Howerton’s absence from the show.

Rob McElhenney said. “He’s in pretty much every episode.”

He’s in the majority of them,” Charlie Day mentioned. Day also went on to speak about how the team went around filling in for Howerton’s absence including an all-female reboot of a part episode in the series.

The latest press release reads:

“Even without Dennis Reynolds, the Gang has its hands full as Charlie hopes to have a child with The Waitress, Mac sets out to understand his newfound sexuality, Dee takes feminism to new heights, and Frank goes to great lengths for the Gang to experience the greatest moment in Philadelphia sports history – an Eagles Super Bowl victory.”

Mindy Kaling will also feature in the show, which she hinted at when she uploaded a photo of herself reading a script from the upcoming season.

The rest of the Gang should be back though: with Olson as Dee, Charlie Day as Charlie Kelly and McElhenney as Mac.

It’s Always Sunny In Philadelphia season 13: what’s the plot?

Obviously it’s early days, but we can certainly expect to see Mac explore his new out-of-the-closet lifestyle and we’ll hopefully find out whether Charlie and the waitress is a relationship built to last.

The title of season 13’s premiere episode has also been revealed as ‘The Gang Makes Paddy’s Great Again’.

Are there any season 13 clips or trailers?

As we creep closer towards the start of season 13, short promo clips have begun to emerge.

A short video released on August 1 parodied the famous shower scene from Alfred Hitchcock’s film Psycho, with Jack Kelly – Charlie’s uncle – playing the murder victim.

That teaser clip followed on from a July 25 preview which depicted such characters as Artemis, Mac’s Mom and Jack playing with a Ouija board.
