Celebrating 15 years of release of the first Harry Potter film - Harry Potter And The Philosopher's Stone, Warner Bros Studios in Watford has opened Harry Potter’s Childhood home - the set for 4 Privet Drive for visitors, where fictional orphaned wizard Harry Potter grew up with the horrible Dursley family. The house is filled with ugly sofas, terrible tiles and vulgar curtains and will be open to visitors from May 27 to June 6. For 11 days in February, the Sorting Hat and stool will be displayed for the first time in the Great Hall set, which was one of the first locations to be built for the Wizarding School Hogwarts. Other props from the film franchise, which starred Daniel Radcliffe, Emma Watson and Rupert Grint, will be on special display for limited period. Half-giant groundskeeper Hagrid's costumes will be exhibited as the techniques used to make him appear so huge. Visitors will also be able to see how the creative effects team worked on the Gringott's Goblin prosthetics, and learn how the giant chess pieces were made to move. Harry Potter And The Philosopher's Stone - the first of eight films based on the books by JK Rowling was released on 4 November 2001.
