I don't know, it almost sounds like a victim of the third movie getting a rewrite to include the bridge to the OT. I read that recently here, so I don't know how reliable it is (maybe someone else will). Basically Lucas was ready to write Episode 3 as a direct sequel to Episode 2 but then was reminded that it was the last one and had to put things in it like Anakin falling to the Dark Side. It makes me curious where he was going before someone gently reminded him what promises were made. I wonder if there was more to the Palpatine/Sidious storyline that was dropped.
Does anyone know what I am talking about (since I plainly do not!)? Does anyone have any insider information on it?
