Q: I've been revisiting the original "Star Wars" trilogy in preparation for "Episode III." I was shocked to see at the end of "Return of the Jedi" the ethereal image of the older Anakin Skywalker replaced by Hayden Christensen's younger version. The change didn't make any sense, any more than if George Lucas had replaced Sir Alec Guinness with Ewan McGregor. I didn't mind all the other little tweaks, but this left me feeling cheated. More than that, don't you think it's disrespectful to Sebastian Shaw? Jimmy Jacobs, Columbia, S.C.
