How Will Glenn Howerton’s New NBC Comedy Affect ‘It’s Always Sunny in Philadelphia’?

Howerton will star alongside Patton Oswalt in the sitcom “A.P. Bio”

Glenn Howerton’s new comedy “A.P. Bio” has been officially ordered to series at NBC, but how will that affect his other job as the star of “It’s Always Sunny in Philadelphia”?

The long-running FXX comedy has already been renewed through Season 14, but the cast has previously stated that the show will be taking an “extended hiatus” before returning for Season 13 as the rest of the cast work on other projects.

Howerton’s co-star Kaitlin Olson, who currently stars in her own broadcast sitcom “The Mick” (recently renewed for a second season on Fox), said in an interview last month that the next season of “Always Sunny” would be pushed back a year.

“We ended up pushing our next season a year because we were all busy with separate projects this year,” Olson said. “So at the end of this coming shooting season of ‘The Mick’ I’ll step right into ‘Sunny’ after that.”

Howerton has also hinted at the possibility that his character might not return for some or part of Season 13. In an interview with TheWrap ahead of the Season 12 finale, the actor said whether he returns will depend on what makes the most sense for the show and his character.

“I want to service the show as best I can, and if we decide the best thing for the show is for Dennis to leave, or at least leave for a while for whatever reasons we come up with, then that’s what we’ll do,” Howerton said. “If we decide it really is best for the show for my character to come back in some capacity then that’s what we’ll do.”

Howerton’s new NBC series comes from “Saturday Night Live” alum Mike O’Brien, who will write and executive produce alongside Lorne Michaels and Seth Meyers. The actor will star as a philosophy scholar who loses out on his dream job and goes to work as a high school Advanced Placement biology teacher.
