I will include a tiny slice of The Empire Strikes Back, because it's a small change that I don't think many people noticed. -The Empire Strikes Back-When R2 gets spit out of the swamp monster on Dagobah here was the original line from Luke Skywalker"Your lucky you don't taste good" and the special edition"Your lucky you got out of there" I'm always confused by this change as it didn't really need to be changed....at all. -American Graffitti -For the dvd a new CG sky(looks pretty) at the beginning. As far as I know the only change. -THX1138-Where do I start on this? Lets just say it got a completely new chase sequence CGI style toward the end among many other changes throughout. I can't really complain that much though, because it is a stunning transfer from beginning to end, and I liked it better than the original. But the fact that the original will no longer even exist for those who liked it is kind of disturbing. *A bit of off the cuff useless information: I always wondered what the fascination Lucas had with the whole THX, and the number 1138 which usually show up somewhere in his movies. I was told by my mega pop culturist friend that THX 1138 was George Lucas's first phone number#. I thought that was kind of funny.
