The Imperial War Museum Official Collection features rare and fascinating original films preserved in the museum's vaults. Many have never been released before and are presented here, complete and uncut, for the very first time. These films are of great historical importance and are essential viewing for anyone interested in British military history. Produced by the Crown Film Unit for the Ministry of Defence and the Admiralty in 1943, "Close Quarters" is an authentic impression of a routine war time Royal Navy submarine patrol in the North Sea, off the coast of Norway. At first patrol is uneventful until HMS Tyrant comes across a U-boat... This quietly gripping and totally believable story of a routine patrol by a Royal Navy submarine was produced by the Crown Film Unit in the documentary style for which it has become famous. All the roles were performed by serving submarines (led by Lieutenant Commander Gregory) and much of the film was shot on a British submarine which was still in service. In general, writer and director Jack Lee got a fine performance from his amateur cast, and the scenes of humour and comradeship are particularly convincing. Moreover, as one would expect, all the tasks and commands aboard ship are carried out with complete assurance and conviction. The interior shots were filmed at Pinewood in a superb full-size model of the submarine, built by a team of riggers led by the art directors Peggy Gick and Edward Carrick.
