Today WB issued a press release on the opening of the Warner Bros. Studio Tour London – The Making of Harry Potter, read it here. Two concept art images have also been released and may be seen in the gallery. Some details from the EMPIRE BIG SCREEN event held today can be read below:

• Warwick Davis, Nick Dudman, Evanna Lynch, Sam Burroughs, Ben Shephard are all here to present and introduce this new experience. It’s going to be HUGE!  Dumbledore’s office, the Great Hall, the corridors – and so much more. All the wands, the costumes – there will be 150,000 square feet of Pure Potter.
• […] we wanted to recreate the creature shop – so you can see everything in the tour. Aragog Buckbeak and many of the other creatures – even the smaller ones, are going to be seen during the tour.
• So, we’ve got a whole host of Potter. Creatures and costumes, full sets and everything which has been preserved from the films (which is a lot according to Nick Dudman) will be on show. Spring 2012 is the vague date…

Thanks to HeyUGuys!
