The Starz series Boss is adding two names to its regular cast for an upcoming second season: Jonathan Groff—most recognizable as the unforgivable Jesse St. James on Glee—and Sanaa Lathan, of Love and Basketball, Alien vs. Predator and Contagion. 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.
