if you refer to my lost footage thread here ,you'll see links to what I mean with the "lost cut" which has 30-40% different material. It was the original cut it was titled "The Star Wars". GL changed it, hacked it up and made "Star Wars" and it was a stand alone movie. 3 weeks after its release theatrically (and seeing success and $$$), he added "A New Hope" to it as the subtitle and in the scrawl, only after this change it was "episode IV". He also changed a few scenes and lines. The original release theatrically which is a memory and impossible to find (though Magnoliafan is working on that with editing) is referred to as the Pre-New Hope Star Wars. So in the 1977, there were in fact 3 different cuts of "star wars" alone...premonitions of things to come and massive changes to be made a la Special editions, 2004 trilogy and the 2007 Archival. Hope that clarifies.
