The Underwater Stage is an underwater film and television studio stage at Pinewood Studios in Iver, Buckinghamshire, United Kingdom. It is the only one of its kind in Europe.[1] The stage was opened in 2005 after four years of planning and development. The stage's tank is permanently filled, and the water is constantly heated, maintained at 30 ˚C (87 ˚F).[2] The water is filtered using an ultraviolet system which creates crystal clear water and a comfortable environment to work in, for both cast and crew.
Plans for the construction of the stage were first announced in April 2004.[3] The stage was opened on 18 May 2005, by Gordon Brown, the then Chancellor of the Exchequer.[4] Brown opened the stage by pressing a button that dropped a car into the water tank.
