Warner Bros. Studios, Leavesden is a 80-hectare studio complex in southeastern England. Formerly known as Leavesden Film Studios and still colloquially known Leavesden Studios or simply Leavesden it is a major film and media complex owned by Warner Bros. The studios and backlot were all converted from the site's original use as a Rolls-Royce plc factory and airfield known as Leavesden Aerodrome, which was an important centre of aircraft production during World War II. It is situated in southwestern Hertfordshire approximately 29 kilometres (18 mi) northwest of central London, in Watford.
Warner Bros. Studios, Leavesden, is one of only a few places in the UK where large scale productions can be made. The studios contain approximately 50,000 m2 (538,196 sq ft) of flexible space which includes stage space, one of the largest filtered and heated stage-based water tanks in Europe, production office space and support buildings, along with an extensive 32-hectare (79-acre) backlot which offers a 180 degree uninterrupted horizon, favourable for exterior sets.

Since acquiring the site Warner Bros. has opened a public attraction called The Warner Bros. Studio Tour – London, which sees over 5,000 visitors a day to the site whilst maintaining a secure studio space within the same complex.
