This might be fun, but I'd hardly call them fan edits, or even worth watching.
Still to this day, the greatest fan edit of them all is "Attack of the Phantom." This total rework of the movie completely transformed the film and is the first time I enjoyed one of the prequels.
Of course, this kind of edit requires a movie that NEEDS it... a film that essentially has a good story but is so bogged down with unesseccary and/or misdirected scenes that a good edit CAN fix it... and it requires a LOT of skill and patience on the part of the fan editor.
When I see "Time for edit: 2 days" I just can;t imagine it's really worth watching.
Let's see if we can come up with films like Attack of the Clones that, with some good editing, can really change a mediocre film into something better.
The Donner Cut of Sup II is another great example, but of course they had access to footage we'll never get our hands on...
