Why do people always say that's Harrison's voice? It really doesn't sound like him to me.
But you could be right about that shot. I still can't figure out why/how the Reel 1 used for the film cells was the revised version, but the Reel 6 was the original. (For those who don't know, I sighted a 70mm cell on eBay where Luke was about to fall off the weathervane, and it was the version seen in the Super 8 with Luke in the center and no radar dish.)
