Another thought. With Lucas selling the moisture farm to the mouse, there could be a Disney joke somewhere?
Palpatine could be watching a Disney movie in his office, (those scenes where he switches off the display when someone walks in) or one of the more evil Disney songs could be playing in the background somewhere in the film.

Anakin could be screaming in agony hearing this as he's being rebuilt. Or it can be coming from his helmet as it's powered on and lowered, cutting off as it's sealed on his head. ;)
