Groff will take on the role of a young staffer in the mayoral office of Tom Kane (series star Kelsey Grammer), replacing Martin Donovan’s character. Lathan will play a new chief of staff who, unlike her boss, has a staunch sense of ethics. It is suggested that the presence and patterns of Lathan’s character Mona will stir up a good deal of trouble between her and Kane. -Deadline

Glenn Howerton is known best as the selfish, vain and manipulative Dennis Reynolds—one of the main characters of an FX favorite, It’s Always Sunny in Philadelphia. Following in the footsteps of his onscreen father Danny DeVito, who stars in the upcoming animated feature The Lorax, Howerton will try out voice acting on the new series Unsupervised. FX’s animated comedy, created and produced by Howerton and several other Always Sunny figures, will feature the actor playing five different characters spread out over two upcoming episodes. It should be something worth checking out—Howerton can definitely put his vocal chords to good use. Unsupervised stars Justin Long and Kristen Bell, and airs Thursdays at 10:30 p.m. ET/PT on FX.

Staff editor Michael Arbeiter’s natural state of being can best be described as “mild panic attack.” His earliest memories of growing up in Queens, New York, involve nighttime conversations with a voice from his bedroom wall (the jury’s still out on what that was all about) and a love for classic television that spawned from the very first time he was allowed to watch “The Munsters.” Attending college at SUNY Binghamton, a 20-year-old Michael learned two things: that he could center his future on this love for TV and movies, and that dragons never actually existed — he was kind of late in the game on that one.
