This is beyond cool! This guy has put together versions of the original trilogy that take an indepth look at how they were created. While the movie plays deleted scenes are added, alternate versions of scenes are explored and almost every scene has text about it at the bottom detailing something about the movie or its creators. There is also comentary from everyone involved from pre production to post production. I find them fascinating. You can find them broken down into 5 minute chunks on utube right HERE.
