Season 15 of It’s Always Sunny in Philadelphia starts on FXX Dec. 1. Two episodes air back to back, then shift to FX on Hulu Dec. 2. 

With the season premiere, It’s Always Sunny moves ahead of The Adventures of Ozzie and Harriet as the longest running live-action comedy series in the history of American TV. Ozzie and Harriet ran from 1952 to 1966. 

The first episode is 2020: A Year in Review and the second sees the gang make Lethal Weapon 7. 

Rob McElhenney, Charlie Day, Glenn Howerton, Kaitlin Olson and Danny DeVito are in the cast. 

It’s Always Sunny premiered in 2005. “The show has become a landmark for dark comedy and American satire, uniting the most devoted of fans from all over the country and abroad, and this monumental 15th season is truly one to crack open and celebrate,” said FXX.

McElhenney created the show and executive produces with Day, Howerton, David Hornsby, Megan Ganz, Rob Rosell, Nick Frenkel and Michael Rotenberg.

FX signed on for four more seasons late last year. “The pitch for Sunny came into FX within the first few weeks of my joining the company in 2004,” said John Landgraf, Chairman, FX Entertainment and FX Productions, at the time. “I was 42 and Rob McElhenney was 27. Rob McElhenney is now 43 and, strangely, I’m now 44— but I’m still at FX and he (with his original partners) is still running Sunny and will be for at least four more seasons. That kind of thing just does not happen in live action TV.” ■

FXX original series It’s Always Sunny in Philadelphia has been renewed for an additional four additional seasons, the network announced Thursday during Disney's investor day presentation.

The series, which will launch its 15th season in 2020, follows the exploits of four bar owners. The series stars Rob McElhenney, Glenn Howerton, Charlie Day, Kaitlin Olson and Danny DeVito. The renewal deal will make It's Always Sunny in Philadelphia the longest live-action comedy series in television history, according to the network.

 “The pitch for Sunny came into FX within the first few weeks of my joining the company in 2004,” said John Landgraf, Chairman, FX Entertainment and FX Productions in a statement. “I was 42 and Rob McElhenney was 27. Rob McElhenney is now 43 and, strangely, I’m now 44— but I’m still at FX and he (with his original partners) is still running Sunny and will be for at least 4 more seasons. That kind of thing just does not happen in live action TV.”

Added Nick Grad, President, Original Programming, FX Entertainment: “We have absolutely cherished our partnership with Rob McElhenney, Glenn Howertown and Charlie Day. It’s extraordinary how with each new season they and their collaborators Kaitlin Olson and Danny DeVito continue to make episodes that stand with the show’s very best and most classic. We’re happy the forecast will remain Sunny for years to come.”

FXX has renewed comedy It’s Always Sunny In Philadelphia for its 13th and 14th seasons, the network announced Friday.

With the renewal seasons, the series, which stars Danny DeVito, Charlie Day, Kaitlin Olson, Rob McElhenney and Charlie Day, will tie The Adventures of Ozzie & Harriet as the longest-running live-action comedy series in television history, according to network officials.

Season 12 of the comedy will premiere in early 2017, according to network officials.

“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, Charlie and Glenn brought it to FX and will go down in TV history as one of the most loved and enduring comedies,” said Nick Grad, president of original programming for FX Networks. “Few shows make it this far or have such devoted fans, and we owe it all to the creative vision and great humor of the creators and cast who keep Sunny fresh and inventive every season.”
