Some of the differences i think id like, but others not to sure about...probably cause it changes the story as im used to it and first saw it. What would be real interesting is a combined version of the two films, basically using the workprint footage to make an extended cut of the released version. I wonder if any of these scenes are available on the dvd as cut scenes...ill need to check that out when i get home. It seems like parts may be able to be restored from the dvd (mainly the cuts) but im sure that most, if not all, of the extended/different scenes wouldnt be accessible without the workprint.
