I've had the privilege of producing the audiobook of Michael Kaminski's "The Secret History of Star Wars", now available on Audible.com.
I first found out about this fascinating book here on originaltrilogy.com, and I thought it would be fitting to give back to this community. So...
The first 5 respondents who reply with a little-known fact about the Star Wars productions will get a code to redeem for a free copy of the audiobook on Audible.com.
I hope you enjoy the audiobook as much as I did producing it!
Edit: Thanks for everyone who participated and got a free code for the audiobook! Congratulations to fishmanlee, doubleofive, twister111, DominicCob, and TK 949! Honorable mention to Bingowings and TV's Frink who also had a go of it.
If you missed your chance, you can still get the book for free by going to Audible and signing up for a free trial. Or check reddit to see if there's any codes left there. An upvote would be much appreciated!
