You know, I would feel pretty bad if I were Sebastian Shaw, and in my two scenes in the famous Return of the Jedi, I never appear in my true form. My performance limited to one of the two scenes (and even then, without my eyebrows), I would feel some serious animosity toward George for doing this on a whim. Replacing me with a teenage kid 21 years after the fact. Same thing with the man that did Boba Fett's voice in Empire. Lucas has changed in many ways since he made the original films, and one of them is his disrespect for some of the actors that helped his films become great. If I were him, I would have asked Irvin Kershner for permission to change the movie. He was the one who directed Empire, after all.
