'Justified' adds Patton Oswalt for Season 4
Oswalt will play Bob Sweeney, a high school classmate of Raylan's ( Timothy Olyphant) who's now a local constable, TVLine reports. Raylan hires him to look after Arlo's ( Raymond J. Barry) house while the old man is incarcerated.
Oswalt has done his share of drama work in the past -- he starred in the rather disturbing movie "Big Fan" and has guested on "Caprica" and "Dollhouse" -- but Bob will have his comedic moments as well. He never tires of retelling his one great football story from high school, and he has a "go bag" at the ready in case doomsday strikes.
In the season premiere, he and Raylan team up to track down a fugitive.
Season 4 of "Justified" begins filming later this month and will be back on FX in early 2013.
