The 150,000-acre exhibition was described as a 'magical opportunity' for fans to see what went into making the films by Mr Johnson as he toured the set and even tried out a wand.

Rupert Grint, who played Harry's sidekick Ron Weasley in the films. said: 'The sets all have tiny details that you may not notice in the films but when you walk through them you can feel the work that's gone into it. It's amazing.'

As well as Diagon Alley and Dumbledore's office, muggles will also be able to walk the stone floor of the Great Hall at Hogwarts and even sneak into the Gryffindor common room as well as see the cupboard under the stairs where harry was sent in Privet Drive.

The original sketches of the sets by Stuart Craig will also be included in the tour and the Oscar-winning designer was on hand as the studio was unveiled, saying how pleased he was that such key pieces of the movies were saved so they could be reconstructed as an attraction.

Josh Berger, head of Warner Bros in the UK, said: 'I am thrilled to be bringing this iconic set to the world. We are incredibly proud.'

Up to 100 of the original painters and carpenters from the films have been involved in putting together the set in it new location.

Tickets for the tour at the studios near Watford went on sale in October and it is due to open to the public on March 31.

Until now, Harry Potter fans have had to travel to Florida and the Wizarding World of Harry Potter theme park at Universal to enjoy a magical thrill.

The park has become so popular that Universal announced it was planning to open a second one in Hollywood, which could be open to the public as early as 2013.
