What is the value of behind-the-scenes reports?
Reports and diaries from the production of incomplete movies (or other media) provide intriguing, tentative hints and clues to the future development of the STAR WARS continuity. However they do not constitute final evidence in debates about continuity and technicalities. The final version of the movie (or publication) may differ from what the preview reporter has seen. Until the final story is available for confirmation and independent measurement, privileged preview reports deserve cautious skepticism. For example, if a character is a proven casualty in Attack of the Clones but behind-the-scenes reports say that he/she survives during Revenge of the Sith then the reports are incredible until proven by the finished film.
