The "Making of Harry Potter" tour in London is as much about how the movies were made as it is about what was in the movies. The tour, mostly self-guided, takes place in two vast Warner Bros. sound studios on the Leavesden Studios lot, about 20 miles northwest of London, where the Harry Potter movies were filmed. For fans, it's one OMG moment after another: the Gryffindor common room, Dumbledore's office, Harry's invisibility cloak, a riot of Hogwarts' portraits of past witches and wizards. Tickets must be bought in advance; information at wbstudiotour.co.uk. NEW YORK TIMES
