So many questions! Will Luke give that classic guttural Navajo "Noooooo!!" when Darth Vader says he is his father? Will Darth Vader go, "Gawwwwwww, the force is STRONG with this one!"
Ha! Of course not. They're dubbing it in Navajo, not in English.
Will they go with the emotions expressed in the movie or will Princess Leia have all the sopping-wet-sponge-enthusiasm of a Bashas grocery clerk in her voice?
Only time will tell, I guess!
