Star Wars

[Aractus]

I looked it up on IMDB...
He was Executive producer on those two films.
And writer for both as well.
IMDB may be wrong, though...

On the content of his changes his reasoning is absurd, for instance: ESB SE (1997) he inserts a scream from Luke as he falls into the abyss - yet in the 2004 he removes it again. In ROTJ 2004 SE he removed Sebastian Shaw and replaced him with Hayden Christensen to appear alongside Kenobi and Yoda. He then claimed that "Anakin died when he became Darth Vader"; yet it's integral to the ROTJ story that Anakin dies in the arms of his son when Vader's mask is removed (this is the bio that was on starwars.com and probably still is).

FYI it's irrelevant whether he was the Exec Producer because:

• "There will only be one. And it won't be what I would call the 'rough cut,' it'll be the 'final cut.' The other one will be some sort of interesting artifact that people will look at and say, 'There was an earlier draft of this.' The same thing happens with plays and earlier drafts of books. In essence, films never get finished, they get abandoned. At some point, you're dragged off the picture kicking and screaming while somebody says, 'Okay, it's done.' That isn't really the way it should work. Occasionally, [you can] go back and get your cut of the video out there, which I did on both American Graffiti and THX-1138; that's the place where it will live forever. So what ends up being important in my mind is what the DVD version is going to look like, because that's what everybody is going to remember. The other versions will disappear. Even the 35 million tapes of Star Wars out there won't last more than 30 or 40 years. A hundred years from now, the only version of the movie that anyone will remember will be the DVD version [of the Special Edition], and you'll be able to project it on a 20' by 40' screen with perfect quality. I think it's the director's prerogative, not the studio's to go back and reinvent a movie."
  ―George Lucas on the Special Editions

Lucas himself says, in his own words, that "it's the director's prerogative, not the studio's to go back and reinvent a movie".

So then, in SW - the one film that he can claim he has a right to make a long string of never-ending "director's cuts" to - first he decides that Greedo shoots first (1997) - he could have done it that way in 1977 in the first place if he had so wanted, but then in 2004 he decides that they shoot at the same time and also that Han Solo moves in a way he never asked Harrison Ford to do in 1977... then he re-inserts Jabba the Hutt to do the same dialogue with Solo that Greedo just did (why?) The extended hanger scene with Wedge is probably the least "offensive" change he made.
