The new edition, revised and expanded, includes information on the last film in the "Harry" series, "Harry Potter and the Deathly Hallows: Part 2," as well as new images from all of the movies. Fans will pore over the colorful pages and backstage insights. In one section titled "The Battle of Hogwarts," set designer Stuart Craig discusses rebuilding the main flight of stairs inside the castle for "Hallows: Part 2." "The staircase needed to be more massive so you could literally wage a war on it," Craig says. The book adds that "thousands of pieces of rubble were cut out of huge blocks of polystyrene and strewn on the stairs and across the courtyard."
