Warner Bros Entertainment (WB) has confirmed that it's Harry Potter studio tour attraction at Leavesden Studios near Watford, Hertfordshire, UK will open on 31 March.

Warner Bros Studio Tour London-The Making of Harry Potter will boast some of the most iconic sets included in the films, including the Great Hall and Dumbledore's office.

Other sets to be included as part of the tour will be the Ministry of Magic; 4 Privet Drive; Gryffindor's common room; and the Hogwarts bridge.

The attraction has been designed by US-based exhibition design company Thinkwell and will cover more than 150,000sq ft (13,935sq m) at WB's studios in Leavesden, Hertfordshire.

Rupert Grint, the actor who played Ron Weasley in the Harry Potter films, said: "The sets all have tiny little details that you may not always notice in the films but when you actually walk through them, you can see all the work that's gone into it."

Tickets for the pre-booked tours have been on sale since 13 October 2011 and it is expected that the tour will attract more than 5,000 people each day.

Plans for the attraction were first announced in June 2010.
