It's Always Sunny In Philadelphia Season 16 Trailer Brings Back The McPoyles & More

The expansive saga that "It's Always Sunny in Philadelphia" has grown into over the course of its 15-going-on-16 seasons has enough supporting characters to populate multiple series of their own, even if such a show would undoubtedly be the stuff of nightmares. The comedic team of Dennis (Glenn Howerton), Mac (Rob McElhenney), Dee (Kaitlin Olson), Charlie (Charlie Day), and Frank (Danny DeVito) have come across a lot of people in their 15 seasons of misadventure, and some of the most notable figures from their pasts are set to come back after some extended absences from the action.

The show's upcoming Season 16, which has already been characterized as a return to the roots of "It's Always Sunny," has gotten a trailer, and longtime fans of the show have reason to get excited for the return of some old familiar faces. Most notably, the season promises more of the McPoyle twins (Jimmi Simpson and Nate Mooney), the Gang's disgusting nemeses who haven't been seen since Season 11. 

Then there is Gail the Snail (Mary Lynn Rajskub) and Bonnie Kelly (Lynne Marie Stewart), both of whom haven't been seen since Season 13's classic gender-flip episode, "The Gang Beats Boggs: Ladies Reboot."

Returning fan favorites are joining Bryan Cranston and Aaron Paul on the show

Of course, Season 16 of "It's Always Sunny in Philadelphia" also promises a few new faces in addition to all the returning familiar ones. And two faces, in particular, are familiar to TV fans — but not because of any previous appearances on this show

With the McPoyles and other "It's Always Sunny in Philadelphia" fan-favorite characters set to return for Season 16, longtime fans of the series are already salivating at the promise of new episodes. And fans of "Breaking Bad" also have reason to get excited, since the new trailer for Season 16 also shows none other than Bryan Cranston and Aaron Paul being chauffeured about by Charlie (Charlie Day). Charlie is also seen addressing Cranston's character as "Mr. Malcolm," which would seem to put to rest any notion that the two stars would be playing their "Breaking Bad" characters on "It's Always Sunny."

Enjoy the new trailer for "It's Always Sunny in Philadelphia" Season 16 above, and watch for the season premiere on FXX on June 7.
