Good interviews with important members of the cast and crew; even includes Sir Alec Guiness. Especially illuminating chats with Lucas about the overall nine part structure of Star Wars. It's interesting to compare Lucas' initial ideas about the sequels and prequels with what was finally released. The highlight of the book is a transciption of a day spent following Irwin Kershner filming on the carbon freezing chamber set (Secrets revealed include the fact that Jeremy Bulloch as Boba Fett was actually desperate to use the lavatory throughout the whole day's shoot). As a collector of Star Wars related books, I have amassed over a hundred, but this remains my favourite.
