I also don't agree that Hayden should as a ghost in ROTJ. Why? Well because it is idiotic. I said this before but I guess I have to repeat it. It was Anakin Skywalker and not Darth Vader who threw the Emporer down the shaft in the Death Star. It was also Anakin who had Luke remove the mask so he could look on him with his own eyes before he died. Anakin died at that point and not at the point of becoming Darth Vader. Since Anakin was saved and died at that age, Sebastian Shaw should not have been replaced with Hayden. I don't give a crap what Lucas says. You don't see Ewan McGregor as the ghost of Obi-Wan do you?
