Some ideas/notes for a Yoda article.
"Irregardless of your opinion if digital or puppet is more believable..."
45 shots containing Puppet Yoda were changed for the blu-ray. Which is 2% of TPM's ~2,246 shots.
Lynne Hale diaries (end of ep.5) has bronze model of the new puppet Yoda and Stewart Freeborn.
Making of TPM doc. 49:30 Frank Oz (while looking at Watto previz) "You don't need me" George Lucas "Things are definitely changing" same discussion but a phrase to use at the end of the article. GL: "We'll always need you."
The 'Puppets to Pixel' doc from AotC, chronicles the evolution of the original model.
Quote from that doc:
09:00 - AotC meeting on Digital Yoda
George Lucas : "The secret is to make him look like a rubber puppet. The problem we got to last time was to make... when they made the upgrade didn't look like the older puppet anymore. So... Then everyone complained that he didn't look real. But he looked better then before yes they made him better but people don't like that. They want him to look like he did before, in the first film."
Mention first appearance of digital Yoda in Star Wars in Concert.
