Warner Bros. Studios Leavesden is an 80 ha (200-acre)studio complex inLeavesden inWatford,Hertfordshire, in theEast of England.[1] Formerly known asLeavesden Film Studios and still colloquially known asLeavesden Studios or simplyLeavesden, it is a film and media complex owned byWarner Bros. The studios were all converted from an aircraft factory and airfield calledLeavesden Aerodrome, a centre of British aircraft production duringWorld War II. The nearest railway station isKing's Langley which is a walking distance of 1.3 miles (2.1 km).[2]
The studios contain approximately 50,000 m2 (540,000 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 ha (79 acres)backlot which offers a 180-degree uninterrupted horizon, favourable for exterior sets. Following a £110 million refurbishment by Warner Bros., the studios are now one of the largest and most state-of-the-art filmmaking facilities in the world.[3] Though the studios are owned by Warner Bros., all of the studio facilities are available to rent for any production. Since acquiring the site, Warner Bros. has opened a public attraction namedWarner Bros. Studio Tour London – The Making ofHarry Potter, which receives over 6,000 visitors a day at peak times. The site maintains a secure studio space within the same complex.

Leavesden Aerodrome was an airfield created in 1940 by thede Havilland Aircraft Company and theAir Ministry in the village ofLeavesden, betweenWatford andAbbots Langley, inHertfordshire.
Construction began in 1940 after the outbreak of World War II. The de Havilland company, who were based in nearbyHatfield, entered into a contract with the Air Ministry to produce what would become known as theMosquito fast bomber aircraft. Space for the large scale hangars needed to produce the huge number of aeroplanes required was not available at de Havilland'sHatfield Aerodrome, so theMinistry of Supply requisitioned this new site in Leavesden, which was an empty plot of land at the time from the Watford Corporation, and it was developed into the complex that it is today. The construction was enormously expensive so parts of the site were leased to theLondon Aircraft Production Group and The Second Aircraft Group. UnderHandley Page, anotherHertfordshire-based aeroplane manufacturer contracted to the Air Ministry, these groups produced theHandley Page Halifax heavy bomber. As a result, by the end of the war Leavesden Airfield was, by volume, the largest factory in the world.[4]
The two planes were both critical successes for Britain during the conflict. Due to the high priority placed on aircraft production, large numbers of workers were drafted with little experience or training in aircraft production, with over half the workforce eventually being female. As part of constructing the aircraft factory an airstrip was created, first so the planes could be tested and later to deliver the craft to their final destinations. The runway and control tower still remain to this day, even after two major renovations, in an effort to preserve the site's history. The runway is now the main road through the complex[needs update] and the tower is currently an observation lounge.
After the war, the aerodrome was purchased outright by de Havilland, who themselves had a succession of owners in the following decades, includingHawker Siddeley from 1959, but ultimately they and the site were acquired byRolls-Royce who continued production and design of helicopter engines. Under Rolls-Royce ownership the RTM322 engine for the UK Apache, Merlin and NH90 helicopters was designed, developed and produced at Leavesden as a joint venture with Turbomeca of France. The airfield was also used by commercial small business aircraft as the field is close to both theM1 andM25 motorways. However, by the early 1990s, Britain's manufacturing industry was in decline and Rolls-Royce had sold their interests in the site and transferred all work to their Bristol facility. Unable to find a new owner, by 1994 Leavesden Aerodrome was left disused and all but abandoned.[5]
The following units were here at some point:[6]
In 1994,Eon Productions'James Bond filmGoldenEye was to be the next film in the series.Pinewood Studios, their traditional home studio, was fully booked with other productions, not being prepared for the series' unexpected return (production had been delayed for several years due to legal issues between MGM and Eon Productions). Facing little time to find a space in which they could build the number of large scale sets required, the production discovered the unoccupied Leavesden. The wide, tall and open aircraft hangars were uniquely well suited to conversion into film stages. Eon leased the site for the duration of their shoot and went about gutting the factories, turning them into the stages, workshops and offices needed for a workingfilm studio.[7] This process is shown on the 2006 DVD's special features. Members of the production crew, impressed by the enormous size of the filmmaking complex they suddenly had to themselves, jokingly called Leavesden "Cubbywood" after Eon's long serving producerAlbert R. 'Cubby' Broccoli.[8]
Leavesden Studios, as the site was rebranded by its owners, quickly became popular after filming ofGoldenEye was completed. A succession of major feature films made use of the site; in 1997, the first of theStar Wars prequels,The Phantom Menace, and laterTim Burton'sSleepy Hollow.

By the year 2000,Heyday Films had acquired use of the site on behalf ofWarner Bros. for what would be the first in a series of films,Harry Potter and the Philosopher's Stone.[11] Every one of theHarry Potter films was based at Leavesden Studios over the following ten years.
While other productions—almost exclusively other Warner Bros. productions—made partial use of the studios, the site was mostly occupied byHarry Potter's permanent standing sets. Indeed, some films, such asSweeney Todd: The Demon Barber of Fleet Street andSherlock Holmes actually made use of some of theHarry Potter sets since they were sufficiently appropriate for theirVictorian setting and tone. During this time, however, it was noted that there were some ways in which the site's facilities might be improved. None of the stages were adequately soundproofed and the WW2 era ceilings had a tendency to leak during rainy weather.
One of the more noticeable exterior sets constructed on the Leavesdenbacklot (outdoors) was a row of ten houses (five per side) along a street, which was created for theHarry Potter series to representPrivet Drive.[12]
On 21 March 2010, there was a fire on one of the Hogwarts sets during filming ofHarry Potter and the Deathly Hallows – Part 2 at Leavesden Studios. Not much of the set was badly damaged.[13]
In 2010, as the finalHarry Potter film was nearing completion, Warner Bros. announced their intention to purchase the studio as a permanent European base, the first studio to do so sinceMetro-Goldwyn-Mayer in the 1940s.[14]

By November 2010, Warner Bros. completed its purchase of Leavesden Studios and announced plans to invest more than £100 million into the site they had occupied for over ten years, rebranding it Warner Bros. Studios Leavesden. The studios make Warner Bros. the only Hollywood film studio with a permanent base in the United Kingdom.
Much of the redevelopment involved converting stages A to H intosound stages and equipping all the facilities with the latest fittings a production might require. The refurbished stages were conversions of the original buildings and the runway and control tower from the site's days as an aerodrome remain intact as well as all of the buildings' original structures. The full scale refurbishment and renovation of the production facilities were completed and the studios reopened to film and television work in 2012.[15][16]
As part of this redevelopment Warner Bros. also created two entirely new soundstages, J & K, to house a permanent public exhibition named the Warner Bros. Studio Tour London – The Making ofHarry Potter, creating 300 new jobs in the local area.[17] Currently the whole attraction is dedicated to the making ofHarry Potter and is now home to many of the series' sets, props and costumes. It was opened to the public in early 2012.
The first film to start shooting at the newly refurbished studios wasEdge of Tomorrow.[18] Though the studios are privately owned, the shooting spaces are available to rent for any production.
On 30 June 2014, Warner Bros. announced the expansion of the studio, building three new state-of-the-art stages and adding a further 10,000 m2 (110,000 sq ft) of office space. The announcements were made after a reception celebrating the Creative Industries, hosted byPrime MinisterDavid Cameron, and attended by WB's CEOKevin Tsujihara and WB UK's MDJosh Berger.[19] Leavesden's trio of new sound-stages consist of one 3,250 m2 (35,000 sq ft) building and two 1,575 m2 (16,950 sq ft) buildings, along with 1,860 m2 (20,000 sq ft) of adjacent office space which were completed by the end of 2014. On the same day the filming of live-actionThe Legend of Tarzan got underway at the studio.[20] Following the refurbishments, the studios are now one of the largest and most state-of-the-art secure filmmaking facilities in the world.[3]
Almost twenty years after the complex was converted from aerodrome to film studios—and over a year since the completion of work on the newly refurbished studios—the site was officially opened by theDuke andDuchess of Cambridge on 26 April 2013.[21] On their visit, they were accompanied by the Duke's brotherPrince Harry andJ. K. Rowling (who had been unable to attend the tour's grand opening the year before), amongst other guests. Several hundred beneficiaries of supported charities were given invitations to the Studio Tour on the day of the visit. The royal entourage visited both the tour and the studios, viewing the props and costumes fromChristopher Nolan'sBatman films, before conducting the site'sinauguration.[22][23]
On 10 July 2019, a fire broke out in one of the studio's sets, and would take responders 15 hours to extinguish. A set for theHBO television seriesAvenue 5 was damaged in the fire.[24][25]

The footage used for theme parks that made use of the facilities include:
The studios have also been used for various music videos and television commercials, most notably support for the video forJamiroquai's "Deeper Underground".


Warner Bros. Studio Tour London – The Making ofHarry Potter is a public attraction inLeavesden Hertfordshire,England. It is a permanent behind-the-scenes exhibition of theHarry Potter films.
The Studio Tour, opened to the public in early 2012. The grand opening event was attended by many of theHarry Potter film series cast and crew members.[39][40]
Each tour session typically lasting three and a half hours,[citation needed] the studio tour has the capacity to handle up to 8,000 visitors daily.[41] Despite Warner Bros. being the studio behindHarry Potter, the tour is not styled as a theme park, due to the fact that Warner Bros. sold the licence to do so toUniversal Studios.[41]
Though the standard tour is self-guided, various guided tours are available at an additional cost.[42]
As early as 2001, on the heels of the success of thefirst film, Warner Bros. planned to build an attraction dedicated to the series in place and so began storing items from the films when they were no longer being used.[citation needed]
The tour's layout and overall presentation was designed by theLos Angeles-basedThinkwell Group in close collaboration with Warner Bros. and the actual filmmakers, includingProduction DesignerStuart Craig,Set DresserStephenie McMillan, Creature DesignerNick Dudman andSpecial Effects SupervisorJohn Richardson.[43] It only includes sets, props and costumes that were actually created for or used in the production of theHarry Potter film series. Sets like the Great Hall, Dumbledore's Office,Diagon Alley, theMinistry of Magic, Gryffindor Common Room and Boys' Dormitory, Hagrid's Hut and a 1:24 scale model ofHogwarts Castle.

Since opening in 2012, TripAdvisor has reportedThe Making of Harry Potter as the highest-rated attraction in the world every year since.[citation needed]
Warner Bros. has continued to put on special features following a seasonal rotation, such as Dark Arts, Magical mischief and Hogwarts in the snow. Some installations like the Wand Choreography Interactive and the inside of the last No. 4 Privet Drive Exterior set have been so popular that they have remained after their respective features have closed.[44]
In January 2015, the attraction's first expansion was announced – a newPlatform 9¾ section, where visitors are able to board the original carriages behind theHogwarts Express steam engine used in the films. The setup includes the locomotiveGWR 4900 Class 5972Olton Hall (dressed as 5972Hogwarts Express) and theBritish Rail Mark 1 train that appeared in the films, brought to life byJohn Richardson's special effects team. Finally a new green screen experience illustrates what working on the films is like from an actor's point of view. This section opened in late March 2015.[45]
