True - the only problem is Lucas' reputation has been on the line for a while and still has seemed to screw things up (in my opinion at least). But hopefully he'll improve.
As for your previous comments - I never suspected her chain was locked into the dais when she was dancing...I figured Jabba had unhooked it and was holding it? It seemed like it at least - same thing with Leia. Then it would make sense for her to escape. But you could definitely be right.
Thanks for the website as well - interesting interview. It's interesting she says she only did the 2 scenes...I swear I saw a picture recently where it looks like 3PO is talking to Oola on the set...but maybe that was a snapshot between takes or something.
