Lucas has for a while now been harping on the prequels and the SE as his original vision for Star Wars. It has long since passed into lore that lucas was forced to make changes to the first Star Wars (by various people, likely the studio or producer Gary Kurtz) to change the tone to make it less goofy, less kiddie to remove lame jokes, etc. Stuff found in Star Wars movies from ROTJ to the SE to the Prequels, since at that point, Lucas had enough power to do what he wanted.

I put forward that if he had made the original Star Wars the way he wanted, it would have been the only movie made. The lame jokes and more juvenile tone would have kept it from becoming the block buster it was. It would have done somewhat well, but not enough to warrant a sequel and if one was made anyway, it would have performed below expectations. But it's doubtful if one would have been made. So then Star Wars would have passed into history as a great movie... for children under 6.

I wish he would rethink his whole "original vision" stance because if he had his way back in 1977, he never would have again. Period.
