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.
