Secret History of Star Wars – FREE book
This is pretty amazing. It’s a staggeringly in-depth account of the making of all six star wars films, referencing just about every interview ever printed, the annotated scripts, and current interviews with key crew members. Because it’s not sanctioned by Lucasfilm – it points out every juicy inconsistency (but remains objective) in the history of the making of these films — and digs up loads of lost facts and new insights.
Best of all – it’s 100% free.
