This weekend the WB Studio Tour London: The Making of Harry Potter officially opens to the public! There will be a grand red carpet event tomorrow to mark the occasion, and over the last couple of days several members of the Harry Potter cast and crew have been doing the publicity rounds promoting this great new attraction.

Yesterday, a press event took place in front of the Great Hall doors with Rupert Grint, Tom Felton, Evanna Lynch, Warwick Davis, David Heyman, David Barron, David Yates as well as the two main bosses of the studio. They answered several questions about: the sets, their memories from them, the impact Leavesden Studios has on the British film industry, other franchises trying to emulate the success of Harry Potter, and more.
