NBC’s Office spin-off plan just took another step closer to reality.

Actress Majandra Delfino has been cast in the NBC project, titled The Farm. The comedy focuses on Dwight Shrute (Rainn Wilson) working as beet farmer and running a bed and breakfast. Former Office showrunner Paul Lieberstein is writing the script.

Delfino will play Fannie Schrute, described as Dwight’s “pseudo-intellectual lefty” younger sister, who previously fled from Schrute farm life for Boston. Delfino has previously appeared on TV shows like Roswell, Quarterlife and State of Georgia.
