I've decided to try and compile a list of sources for future reference and was hoping someone could give me a hand. I seem to have misplaced my DVDs and I was wondering if anyone would be kind enough to point out where exactly on the RotS commentary that Lucas claimed Vader has 80% of Palpatine's power. I know it's there, I just cannot recall the precise location. Also, if anyone can point out where Lucas states Luke achieved his father's potential, as well as claimed Palpatine was the strongest sith lord, I would be very grateful. If memory serves, those two are on the ESB commentary?
