I love watching DVD special features about how novels get converted to books. Harry Potter Page to Screen is like an extended written version of one of those featurettes.
At over 500 pages, this is a huge, coffee table sized book. There are plenty of fantastic pictures, particularly in the second half of the book. The first half of the book goes movie-by-movie through the series, detailing changes in directors, casting information, and technical challenges for each film. The second half of the book focuses on individual characters, settings, creatures, etc.
This is a beautiful book, and I learned a lot of behind the scenes trivia that I hadn’t known about the series before.
