When does The Office return?

The Office is a British mockumentary television sitcom first broadcast in the UK on BBC Two on 9 July 2001. It follows the day-to-day lives of office employees in the Slough branch of the fictional Wernham Hogg paper company. Two six-episode series were made, followed by a two-part Christmas special. The show centres on themes of social clumsiness, the trivialities of human behaviour, self-importance and conceit.
The show is a mockumentary based in a branch of a large paper company called Wernham Hogg in the Slough Trading Estate in Berkshire. The office is headed by general manager David Brent (Gervais), aided by his team leader and Assistant to the Regional Manager Gareth Keenan.
