The Office Casts Dwight's Sister and Nephew

The Dwight Schrute spin-off is coming together.

Majandra Delfino and Blake Garrett will guest-star in an upcoming episode of The Office, TVLine.com reports.

NBC developing The Office spin-off about Dwight Schrute

Delfino (Roswell) will portray Dwight's (Rainn Wilson) sister, Frannie, while Garrett (New Girl) will play his nephew, Cameron, in a Schrute farms-centric episode of The Office this season. Should NBC decide to move forward with the spin-off, both actors will become series regulars.

The potential series, which would tentatively launch in early 2013, would follow Dwight's life outside of Dunder Mifflin at his family's beet farm and bed and breakfast. The beet farm has been featured in several episodes stemming back to Season 2, with The Office and Parks and Recreation executive producer Mike Schur playing the role of Dwight's business partner and oddball cousin Mose.
