Notice there isn't a big interest in re-edits for Spider-Man or Lord of the Rings or even the new Batman movie. Good films aren't being screwed around with.
...I know it is a little late to reply on that, but anyway, ADM: I disagree ;-) There was this not to well done trailer for the hobbit, made from TLOTR pieces and some computer game music as far as I remember and that one was downloaded at least 100000 times although everybody knew it was fake. Editing good or great movies is very different to editing the bad ones. A good one is maybe not possible to be improved, but it may be watched from a new point of view and therefore receive attention by an audience hungry for more. Personally I would love to edit Spiderman and get rid of most of the green cobold which by far reminded me to much on Power Rangers, but that is simply not enough. But if someone would be able to get the 6 hour workprint edition of Return of the King, which was the first final cut they had... I think the interest would be gigantic, don't you?
