NBC has brought Mena Suvari and Kyle Howard in to co-star in the untitled single-camera sitcom created by Hilary Winston (Community).  The story centers on "a shy, focused woman who, after being dumped by her fiance, leans on her co-workers to help her come out of her shell and plot her revenge."  Suvari and Howard play two of the woman's co-workers.  Suvari is described as a "hard partyer and unabashedly promiscuous."  Howard is a former football player.

Hit the jump for more pilot casting news.

NBC cast Michael Raymond-James as one of the leads lead in the thriller Midnight Sun.  Based on an Israeli series, Midnight Sun centers on "the mysterious disappearance of Midnight Sun, a group living on a cult-like commune in Dugan, Alaska, and a female FBI cult specialist leading the investigation that uncovers a larger conspiracy."  Raymond-James will play an Alaskan lawyer who serves as the second-in-command of the Dugan Police.  I first noticed Raymond-James from across the room in True Blood.  I fell in love after Terriers.  Really happy to see him land the lead in a network pilot, no matter where it leads.

Finally, Deadline reports that Jonathan Jackson has joined the cast of  Nashville.  The ABC pilot revolves around "the rising and fading stars" in the Nashville music scene.  Jackson will play one of the rising, a "bad boy musician" and aspiring writer.  Callie Khouri (Divine Secrets of the Ya-Ya Sisterhood) wrote the script.  RJ Cutler (The September Issue) will direct.
