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