Mike Ausiello in his TV Guide Blog has reported that NBC plans a spin-off from the Office featuring characters we have not met yet. There is to be an episode of the Office coming up, however, that will introduce these new characters to us. NBC is reportedly seeking one ‘name’ for the show similar to Carrell in the current Office series.

From Wikipedia:
The Office is the title of multiple television situation comedy shows. The first was the UK version, created by Ricky Gervais and Stephen Merchant. Initially broadcast on BBC Two on 9 July 2001, it ran for two seasons plus a two-part Christmas special. The show’s success prompted NBC to create an American version, which premiered on 24 March 2005, two years after the original ended. Despite an outcry from fans of the original, the US version recovered from a shaky start to become very successful in its own right. The US version is based in Scranton, Pennsylvania, which is a real city. References are made throughout the show based on the real city of Scranton regarding restaurants and other landmarks such as Lake Wallenpaupack. An office convention has started in Scranton, Pennsylvania. Gervais and Merchant are credited as executive producers of the show along with Ben Silverman, Howard Klein and Greg Daniels. Other than the Pilot episode, the scripts for the US version are original, and not adaptations from the UK, although some scenes and some general story ideas are based on the original.
