Add in a snappy new title, and i'd agree with Duchamp, you've got a new work
And I'd say that the 2004 'STAR WARS:A New Hope - Special Edition' did indeed come across as a 'new work' in many respects. Not that I was against that, if that's what GL wanted to do at some point. That was fair enough, and was certainly of some interest, whether you ended up appreciating all his latest 'creative changes', or not. Personally, I reckon adywan's 'new work' kicks it's ass in comparison.
But what I certainly didn't expect to happen, was a complete disregard for the much-loved 'original work' known as 'STAR WARS' (or 'STAR WARS:A New Hope' if you must) by GL. The one that smashed box-office records to become the number one movie of all-time, on it's release. And by default, I didn't expect a complete disregard to properly preserve the work of others that were involved in it (and it's sequels) either...especially from someone who had a reputation for being at the forefront of technical excellence, and who claimed to have a keen interest in the preservation of cinema history.
Of course, the current poor treatment of the 'original works' could just be a misunderstanding on our part, as we may find that they've actually been faithfully preserved in something approaching their original look after all...and will be released in a respectful, high quality standard eventually, after all. In the meantime, it's difficult to believe that, sadly.
