I must admit that when i heard that Gauntlet Press wanted to make a book about that short story, and more precisely about its adaptation, i was a bit skeptical about the interest of such a book.. because the story is pretty short : how to make a complete book about it?
But Gauntlet Press managed to put together a really interesting set of interviews and contributions from all sorts of people involved in this episod : from the screenwriter to the producers, the SFx experts, the composer... and let's not forget, William Hunt, which is known worldwide as an actor with a "specific" voice, but that had to do his performance without saying any word.
This book cannot be read... one can only devour it.
In my opinion, the 3 main elements of this book are : Stephen King's short story, Richard Christian Matheson's script, and the storyboard (which can be read as easily as a graphic novel. Well, once again, it cannot be read : one would find himself turning the pages compulsively!).
The storyboard itself is a good reason to buy this book.
