I'll soon be able to see some of the pictures people have been posting from The Making of The Empire Strikes Back, as I bought a new copy tonight through Abebooks for $48 from the U.K., free shipping. A guy at eBay has a used copy for $45...but I just found out he wants $33 to ship it. :p
Anyway, what little I've seen from it so far looks like it could be quite inspirational and potentially important for Revisited, what with the models and behind-the-scenes pictures.
