This is simply a fascinating book. I received it for Christmas and am having a hard time putting it down. The bright photos make it absolutely beautiful to look at, but Steve Sansweet and Peter Vilmur have also provided a lot of interesting text as well.
They've divided into sections for each movie, and it's taken me days just to get through the first movie. I find I keep looking back at the posters again and again.
Anyway, if you're interested, I'd say it's money well spent. Check out your local book store or Amazon
