Joe Williams who wrote Lapti Nek was removed from the credits in '97. It said so on the star wars site but couldn't Lucas get in a lot of trouble from erasing someone's name from the film. Isn't there a rule against that which is why many full-screen dvd's (including star wars) have the credits in letterbox widescreen?
Anakin's ghost appears at the age he was last alive. With Hayden, that means Luke was NOT right and basically destroys everthing Lucas supposedly wants with Anakin's redemption.
"I've learned that we can do just about anything under the sun with computers. So the question becomes, should we? ...But now, we have technology that can replace actors, or an entire performance in an already existing movie. We could cut out Humphrey Bogart and replace him with Vin Diesel, if somebody wanted. Who would want to? Well, there might be people who would. That's why we have to be careful. Movies reflect our cultural heritage from the period in time in which they were made. Therefore, altering them can destroy that historical perspective. That's disrespectful of history, which is a big issue for me. The situation is like walking a tightrope - we have to move forward, but we have to be careful."
-Steven Spielberg
