Warner Bros. Studios, Leavesden is an 80-hectare studio complex in Leavesden in Hertfordshire, in southeast England. Formerly known as Leavesden Film Studios and still colloquially known Leavesden Studios or simply Leavesden, it is a film and media complex owned by Warner Bros. The studios and backlot were all retrofitted as the site's original purpose was as an aircraft factory and airfield called Leavesden Aerodrome, a centre of British aircraft production during World War II. It is situated in Abbots Langley, near Watford, in southwest Hertfordshire.
Warner Bros. Studios, Leavesden is one of only a few places in the United Kingdom where large scale film 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, workshops and support buildings, along with an extensive 32-hectare (79-acre) backlot which offers a 180 degree uninterrupted horizon, favourable for exterior sets. Following an over £110m refurbishment by Warner Bros. the studios are now one of the largest and most state-of-the-art secure filmmaking facilities in the world.
