The official site has a multi-page profile of Don Bies, Lucasfilm’s go-to guy for keeping droids in check. Some interesting insight on the unique issues of working with Artoo and Threepio. Spoilers are fairly minor – just don’t look too closely at the pictures.
In other Ep3 news, some collector cards have gone up on eBay, with new images and some spoilery information. Check out the auctions here and here. See them at IESB. Watch for MAJOR SPOILERS.
