I'm kind of on the team for having jar jar speak basic as well. I simply cannot connect with an alien character that talks all the time, yet is babling in an alien language...it just doesn't connect with with the actors or story flow. I know that chewbacca never uddered anything in basic, yet he wasn't in full conversations with ANYONE , except solo on brief occasions. It just makes jar jar more useless if I have to stop and read what he is saying all the time....especially since we will be doing that for the nemoidians and any other alien through the movie. And his mouth movements are NOT limited to his dialouge on screen in the original. He has a huge CG beak/mouth that only animiated the words to a certain point, I think it would be easy to drop new words on top of his actions that contradict what was in the script. Although i'm not really into the idea of him having a scottish/irish/british/australian twist at all. When i looked at the character of jar jar before I knew what he sounded like, I imagined that he had somewhere between a deep/normal tone and that he spoke in broken sentences. He did seem like he was a frightened/weak individual that was having trouble adapting to the cruel universe and I thought that would reflect in his story........which it could have.......and could yet. I mean, we do have the ability to make this character interesting and add some depth to him through Episode 2. I just wouldn't want us to treat the character like it is completely hopeless and will ruin whatever celluloid has his presence.
