I hope Rinzler's promise to George to not write any more books on the making of a star wars film was just a joke. He mentions it in the book. I want to see him write the making of Episode VII.
Would have been interesting to see him pen better making of books for Phantom Menace or Attack of the Clones but doubt they will do those there is probably no interest.
The original trilogy storyboards book looks to be interesting. Now i sort of see why there were about none of them in the making of empire or jedi they wanted to sell more books.
I know the first book making of star wars only had selected ones in the premium hardcover as a bonus.
