'It's Always Sunny': Howerton Nearly Left After S11

Glenn Howerton, co-creator and star of 'It's Always Sunny in Philadelphia,' revealed he nearly quit the show after season 11, driven by concerns that the series had peaked and anxiety about missing other career opportunities. During the show's 20th anniversary panel, Howerton clarified that his desire to leave predated his role in NBC's 'A.P. Bio' and was unrelated to other projects. Despite stepping back from the writers' room during seasons 13 and 14, he remained a main cast member. Co-creators Rob McElhenney and Charlie Day continued writing him into the series, which contributed to his return. The show's collaborative and flexible environment has helped sustain its longevity, and it continues into its 17th season. Howerton has maintained his appreciation for the series throughout.
