I thought this was a pretty interesting book -- though I'm not sure I would recommend it to anyone less engaged with Star Wars than a casual fan.

I gather that this was completed prior to Lucas selling Star Wars off to Disney and the new sequel series(es), so it doesn't exactly cover everything. Still, walking through all the different drafts of the original and sequel trilogies (such as the were) was intriguing. I especially enjoyed seeing parts of the older drafts being picked back up and used later on (Mace Windy, for example).

I suppose the main angle of the book, aside for chronicling the film production, is exploring all the evidence that Lucas never had a complete vision of the movies prior to making them, and it pretty convincingly details the contradictions in production interviews and the various drafts of each movie.

A personal nit to pick: the book uses a lot of interview quotes. The audiobook didn't include the actual audio of those interviews, so the narrator does his best impressions of the people speaking ... which I don't know if there is a better way to accomplish those quotes in an audio format, but it completely distracted me (although his Liam Neeson was pretty good).

Another personal note: I listened to this audio book after rewatching the Plinkett / Red Letter Media deconstructions of the Prequel trilogy and they made an interesting coupling - I would recommend them both to any Star Wars fan.
