See What the Cast to Dwight Schrute's "The Office" Spin-Off, "The Farm," Looks Like
Here's the character descriptions and the casting on the series.
FANNIE SCHRUTE | Attractive, urban and in her late 20s/early 30s, Dwight's younger sister fled the Schrute farm life for Boston as soon as she could, and has had little to do with her roots for quite some time. Now divorced with one son, Fannie is "a bit of a pseudo-intellectual lefty" with an ironic sense of humor and a great heart.
Played by Majandra Delfino
JEB SCHRUTE | Dwight's easygoing thirtysomething brother hasn't done well in any of the career paths he's followed - worm breeder and Bigfoot hunter among them -- but has found some success with a pot farm. He's got none of Dwight's dedication or work ethic, but he has made an exercise video about things you can do with a knife and a canoe.
Played by Thomas Middleditch
CAMERON WHITMAN | Dwight's smart and slightly weird 9-year-old nephew (Fannie's son) is a cosmopolitan lad who nevertheless feels the pull of his Schrute heritage, especially when he's around someone -- his uncles, perhaps? -- who can offer the fatherly guidance he lacks.
Played by Blake Garrett.
HEINRICH MANHEIM | The Schrute siblings' great uncle is charming, greedy, manipulative... and just may have had to spend time in Argentina following World War II, thanks to his German National Socialist roots. Oh, and he vows to kill Dwight by the end of the first episode.
In addition, Dwight's cousin -- who was originally written as a recurring/guest character but has been expanded to a full cast member -- is being played by Matt Jones, best known as Badger from Breaking Bad.
