A word for anyone tempted to buy anything/everything related to THE MATRIX: the complete contents of THE MATRIX: THE SHOOTING SCRIPT (including the scene notes) can be found in THE ART OF THE MATRIX, which contains additional material, both written and pictorial. I enjoy the material in THE SHOOTING SCRIPT version, but prefer the more detailed treatment in the bigger book.
Even the text of William Gibson's introduction appears in THE ART OF THE MATRIX, as an afterword. The author of NEUROMANCER and JOHNNY MNEMONIC was slow to see THE MATRIX when it first came out, knowing that it was in his own genre - although he'd been exposed to the screenplay, he hadn't anticipated how well the story would translate to film. Not only did he enjoy it when first persuaded to see it in theatrical release, he promptly turned around and dragged others out to see it. :)
The scene notes following the body of the script aren't written by the Wachowski brothers, but by their assistant Phil Oosterhouse - the brothers being busy at the time with making the sequels. The notes accompanying THE SHOOTING SCRIPT omit discussion of some deleted scenes, but otherwise tally with the more complete version in THE ART OF THE MATRIX.
Essentially, this book is for anyone who's interested only in the no-frills text of the script, without the storyboards that were essential to the Wachowskis' campaign to persuade Warner Brothers to actually make the film, and without any extra discussion of scenes that were cut before the movie was actually shot. As far as it goes, it's fine.
