ABC News also got a sneak preview of Warner Bros. Studio Tour London - The Making of Harry Potter, where their clips showed more of a floor plan of the sets at Leavesden in the U.K. where guests would walk through to see such locations as Dumbledore's office, the Great Hall, Diagon Alley, and a CGI section where the cast filmed Quidditch sequences. The clip also shows the first look at the Gryffindor common room and boys' dormitory at the Harry Potter studio tour, set to open to the public on Saturday, March 31, 2012. That can be viewed here.

ABC spoke to production designer Stuart Craig on his sets; he noted that he knew he created the right sets when receiving J.K. Rowling's approval.
