Well I was away all last week, so this was the first online chat I didn't take part in (although he DID answer one of my unanswered questions from the previous chat ).
Here's some Episode III info revealed by him (although not much):
- C-3PO says "Damage" at some point in the movie (Tony argued with Lucas to change it from "Hurt").
- 3PO has scenes with Palpatine.
- The fight scenes are "thrilling and frightening"
