Joining the brothers for the 6pm switch on of the festive decorations were members of the cast from Watford Palace Theatre’s Christmas pantomime, Jack and the Beanstalk.

“When we were filming we were based in St. Albans or at the Grove hotel down the road so we have a lot of good friends in Kings Langley and Watford” Mugglenet reported the boys as saying.  Filming for the Harry Potter series took place at Leavesden Studios which is located just outside the town.

The event at the hotel which is adjacent to Leavesden Studios attracted “scores of people” according to the local newspaper who came to find out details of jobs on offer at the site.

When Warner Brother’s purchase of Leavesden Studios was first announced it was believed that around 300 jobs would be created at the visitor attraction which is to be opened at the site where Harry Potter has been filmed for the past decade.

The tour around two newly constructed sounds stages at Leavesden Studios will enable Hogwarts fans to get up close and personal with behind the scenes magic.

Visitors will be able to walk through sets used during production of the most successful film series of all time including those of the Hogwarts Great Hall, Dumbeldore’s office and Hagrid’s hut.

The three hour experience will enable Potter fans to see incredible set detail, original costumes, and some of the magic behind the special effects in the movies.

Tours will be by advance booking only to ensure that high visitor levels do not spoil the experience. Tickets will be priced at £28 for adults and £21 for children with the first Leavesden Studio tours taking place in Spring 2012.

From 4:30-5:15pm holders of Empire Presents diamond tickets will be able to find out further details of the behind-the-scenes Harry Potter attraction which is due to open at Leavesden, just north of London, in Spring 2012. Also attending the live event at Greenwich Peninsula will be members of the cast and crew from the Harry Potter film series.

A Warner Brothers spokesman said “The unique tour will give visitors the first ever chance to visit the real Harry Potter film sets to learn more about the workings of the breathtaking special effects and the incredible animatronics, as well as experience the sheer scale and incredible detail of the sets used by the cast and crew on all the films.”

“The event will culminate with an exciting announcement that both film and Harry Potter fans will not want to miss.”

It is no longer possible to obtain tickets to the event.

All companies attending the jobs fair which is to be held at the Langley Banqueting and Conference Suites, Watford High Street on 30th June will be offering at least one vacancy, apprenticeship or internship at the event. With over 50 companies already booked up to attend job hunters will have plenty of options to consider.

Speaking to the local newspaper Watford MP Richard Harrington said “I am particularly excited that Warner Brothers have agreed to attend, as the redevelopment of Leavesden studios will provide thousands of new jobs for local people.”

The Harry Potter Experience Leavesden, due to open in Spring 2012, will offer visitors the opportunity to tour selected sets used during filming.

An embargo placed on information relating to the second film must be just about to end as a number of sites have started to trail future posts about their Leavesden Studio tours.  Collider have posted a series of on-set interviews with actors from Harry Potter and Deathly Hallows Part 2 conducted on set at Leavesden Studios whilst Harry Potter fan site The Leaky Cauldron have announced that they too will soon be posting their full Deathly Hallows: Part 2 set report.

The final film in the series Harry Potter and the Deathly Hallows: Part 2 will be released on July 15. The Warner Brothers Leavesden Studios tours which will enable ticket owners to see sets and drops from the film as well as other Hogwarts memorabilia is due to open in Spring 2012.

Adverts posted online at the end of last month show the film studio is looking to hire a “Director of Retail & Commercial” for work at Warner Bros Studios Leavesden. The candidate must learn from experiences at NBC Universal Wizarding World and maximise sales including ancillary revenue from audio tours, guidebooks and photography.

Studio management are also looking for a Food & Beverage Director who will be responsible for setting up and overseeing the operation of a film production kitchen, canteen as well as the Leavesden Studio Tour café and public coffee points and kiosks.

On the production side the search is also underway for a new Health & Safety Manager as well as a Facilities Manager to ensure that the 9 sound stages and visitor attraction are safely operational.

Just 8 days later on Friday 18th March a second fire destroyed a set from the upcoming Harry Potter and Deathly Hallows Part Two film. The set, which was located outside, started to burn at 9pm whilst it was being used to film a battle sequence from the Harry Potter movie.

Speaking to the local newspaper a spokesman for Warner Brothers downplayed the incident stating that there had been “no damage to Leavesden Studios at all”. He added that the fire, which took place when none of the main cast members were on site, was extinguished quickly and caused only limited damage.

The Sunday paper also suggests that the Leavesden attraction will be more like a theme park than the plans submitted to the local council suggest. Warner Brother’s position has always been for a more low-key studio tour setup for which advanced bookings would be required.

Harry Potter website The Leaky Cauldron has stated that claims of a Leavesden “theme park” are inaccurate.

The contractors, who will be working on site for six months, are tasked with stripping away internal ceilings and soundproofing material from the converted aircraft hangers as well as performing more substantial removal of scaffolding, roof panels and skylights from the main structures.

The job will have to be a careful one however as some sets and film archive libraries will still be inside Leavesden studios whilst work is underway!
