It was nice to see the Pruneface highlights (officially Dresselians), and I loved the footage of the (unused) Cane Adiss (2 headed giraffe-like creature in Jabba's palace) which I had only previously seen pics of in the Star Wars Chronicles. Have you got the Chronicles? There's some very nice, rare pics that would have worked nicely in this docu (Ten Numb, A-Wing pilot, for example). Nien Numb puppet footage would have been nice (sure I've seen that somewhere before) but other than that, it was pretty comprehensive.
If you do go ahead with the ANH docu, I'd be happy to help with rare Chronicles photos if they're any good to you.
