I seem to recall someone thinking that the mustafarans working on one of the floating lava platforms during the duel were there in one version and gone in the other. Again, I don’t know if this was ever confirmed.
Was there only one U.S. theatrical version of RotS or were there differences between the 35mm prints and the DCPs? I saw both, but I wouldn’t be able to tell you now if, for example, the wipe was there in both versions or if that change predated the dvd. I think the wipe is back in the official bd if I’m not mistaken?
