"When he first showed up, my initial reaction was pure excitement at seeing Tarkin again," one visual-effects artist who works with Disney (and asked not to be named) told me. "I had no idea it would be more than a little cameo. The more he did, the more I wondered why they were using him so much. He seemed as believable to me as I think they could have achieved. Everything looked great visually, but there was something off in the animation. The lips always give it away for me. There is a subtlety to mouth movements that gets lost in the motion-capture."
