Harry Potter Page to Screen will be released on Oct 25, 2011.
I've managed to find some page previews online, some from the French edition of the book.
It looks like it's going to be the encyclopedia of Harry Potter, the definitive edition fans have been waiting for.
There are lots of photos of the film sets, actors, props, memorabilia, etc. You'll also get to read about the making of the film from stories told by the cast and crew. Everything is beautifully laid out, captioned.
You can pre-order the book from Amazon now. They are also offering Release-Date delivery for the book.

If you buy from the links, I get a little commission that helps me get more books to feature.
