Boss Adds Sanaa Lathan and Jonathan Groff for Season 2

According to Deadline, Boss is restocking its cast after its explosive first season finale this past December. Entering into the increasingly dirty landscape of Chicago politics are not one but two fresh faces in Sanaa Lathan and Jonathan Groff. Lathan will be playing Tom Kane's new chief of staff Mona, while Groff is set to portray Ian Todd, the latest voice in Kane's ear.

Though most known for her work in films like Love & Basketball and The Best Man, Lathan currently voices Donna Tubbs on Fox's The Cleveland Show and has made appearances on Nip/Tuck, Family Guy, and NYPD Blue. Groff last appeared on Glee's second season finale (titled "New York") as the villainous Jesse St. James, but he's been featured in The Good Wife and One Live to Live, respectively.

Going into season 2 of Boss, Kane is more or less alone, following the betrayals he suffered at the hands of Kitty and Ezra, as well as his own vicious treatment of daughter Emma. He may still have Meredith on his side, but there's still a distance there and an assumption that they're merely propping up one another's careers at this point. (Meredith's addiction to power stopped several near-sabotages to Kane's chances, including her flirtation with newly-minted gubernatorial candidate Ben.) Mona and Ian are good starts at rebuilding the empire that nearly crumbled around him, but Kane will have to continue battling for his health in addition to battling for his political life.

Though earning fair reviews for its debut season, Boss ended up being nominated for two Golden Globes, with Kelsey Grammer's performance as Mayor Kane taking home the award for Best Performance by an Actor in a Television Series - Drama. Grammer's one of the leading Emmy contenders in 2012, possibly the man most likely to defeat Breaking Bad's Bryan Cranston.

Boss returns for its 10 episode second season this fall.
