Harry Potter fans can catch a glimpse of how the movies were made starting in spring next year, when Hollywood studio Warner Bros. opens the doors of its Leavesden facilities where much of the franchise was filmed.

Called Warner Bros. Studio Tour London -- The Making of Harry Potter, the tour will feature original sets, costumes, props and effects used in all eight "Harry Potter" movies.

Among the exhibits on the three-hour tour is the set for the Great Hall at Hogwarts School of Witchcraft and Wizardry, headmaster Dumbledore's office and other attractions to be announced at a later date.

Currently under construction outside London, Warner Bros. Studios Leavesden is set to be one of the largest studio production facilities in Europe when it opens next year.

The Hollywood studio's relationship with the site stretches back over 10 years, and has seen the production of all eight Harry Potter films as well as other recent Warner Bros. pictures including "The Dark Knight" and "Sherlock Holmes."

The seven Potter movies screened to date have amassed around $6.4 billion at the global box office. "Harry Potter and the Deathly Hallows Part 2", the final installment, is set to hit theatres on July 15.
