One interesting note from the event: Producer Rick McCallum and ILM animation director Rob Coleman confirmed that Lucas has continued to digitally massage the other Star Wars films. Specifically, Coleman indicated that the puppet Yoda from Episode I has been replaced with a digital Yoda that matches the character as seen in Episodes II and III. The CG performance was specifically tailored to match to Frank Oz's puppet performance. You'll be pleased to know that Coleman also told me, in no uncertain terms, that Oz's puppet work in The Empire Strikes Back and Return of the Jedi will NEVER be replaced with CG. So you fans can rest easy. You'll get to see the new changes on a future, as-yet-unscheduled box set release of the entire Star Wars saga on DVD and/or HD.
One other interesting item to report from the event: McCallum expects there to be 22 Young Indiana Jones Chronicles DVDs in all, 3 of which have been completed. The discs will include some 66 historical featurettes, now in production. Work has been ongoing for about 18 months on the Young Indy DVDs, with about another 18 months worth of work yet to be done. If all goes well, the plan is to tie the DVD release to the theatrical debut of Indy IV (the script for which Lucas is expected to finish this Sunday).
