Every "Art of -" book should be like this. Every. Single. One.
The art is absolutely amazing, and this book doesn't just have conceptual sketches, but also includes the storyboards! These weren't any ordinary arrow-heavy, sketchy storyboards either, but fully realized graphic novel panes that perfectly captured the stylistic approaches that were eventually translated into film. It truly is amazing just how much of the action from the boards was replicated in the final cut, really showing the skill of the artists and the minds of the directors that worked with them.
Now, the concept art was what I really loved looking at in this book, especially since I'm going to college next year to major in art with a focus on illustration, and cinematic concept art is one of the paths that I'm really drawn to (sorry, bad pun) for a career choice. Due to the fact that the pre-production process for The Matrix occurred before the hostile takeover of digitally rendered concept drawings (drawn directly into the computer, which allows for easier alterations at the director's request), all the concept art was done in traditional mediums. Don't get me wrong, I love more modern concept art, but seeing all of these beautiful drawings that were created in traditional mediums really touched me (I'm an art geek okay, I know it sounds weird).
Not only does this book have the art, it also has the COMPLETE shooting script! It's fascinating to see all the slight alterations and action instructions, all impeccably written. From cut scenes to descriptions of what the characters were supposed to be thinking, this book has it all.
I would seriously recommend this book to anyone. It truly gives the scale of just how massive the creative process that goes into making a film, especially a film as great as The Matrix, and gives one a new appreciation for the unseen heroes of the movie industry...the artists.
