Oh by the Force, I'm so sorry. I JUST found the Endor tidbit in the "story of ILM" documentary. I have no idea how I could have missed it when I watched it last night. Will re-watch in case the Jabba scene is in there as well. Good lord.
@ zombie84:
You're most likely correct. It's absolutely possible that there was a two-hour special, one half of which is the ILM, and the other half of which is a re-run of one of the SE specials you're referring to. Can you tell me the title[s] of the specials you're thinking of?
