EXCLUSIVE: NBC has set another key member of the Schrute clan. Veteran Tom Bower (Die Hard 2) has been cast as Dwight’s (Rainn Wilson) great uncle Heinrich in The Office spinoff project, which will be introduced in an episode of the veteran NBC comedy’s upcoming final season. Titled The Farm, the spinoff has Dwight (Wilson) living at the Schrute family beet farm and bed & breakfast. Bower will play the Dwight siblings’ (Wilson, Majandra Delfino, Thomas Middleditch) great uncle Heinrich Manheim, who is charming, greedy, manipulative… and may have had to spend time in Argentina following World War II, thanks to his German National Socialist roots. Co-starring in the project is Matt Jones as Dwight’s cousin Zeke. Bower, repped by UTA and Principal, will next be seen in the feature Out Of The Furnace and reprising his role as Pop Pop on It’s Always Sunny in Philadelphia.
