The practice of making Official Movie Books like this has somewhat faded since it's heyday in the 1990s. Back then, before the internet this WAS the only way to see behind the scenes stuff. Sure it's all sanitised and studio-approved soundbites but
I had this as a kid and absolutely loved pouring over it. Pretty much all of the concept art and interesting pictures I've already scanned for the website. So don't feel like you're missing anything.
As a bonus, I also take a quick look at the books for Batman (1989), Batman Returns and Batman & Robin and I also flick through the Official Magazine of Batman Forever. Again, that has been scanned for this website and can be viewed here.
Anyway, I cannot recommend the Official Movie Book enough. It's a treasure trove of material and copies fly around on eBay, Amazon, Abebooks for pennies. You've got no excuse to have a copy on your shelf.
