I am interested in what you all think about turning episode 3 into a standalone prequel film.

I have always considered it the best entry in the prequel trilogy, mainly due to it’s compelling story. It would be great to view it in a marathon as the only prequel but this would require a new crawl and maybe some other changes in the story.

What would have to be included in the new crawl, among other cuts/additions to make it work as a standalone prequel film?

I think some of the biggest challenges are establishing the array of villains in the movie and Anakin/Obi Wan’s history. And the past can be altered since episode 3 would stand alone. The crawl could even specify that Anakin was found by the Jedi as a teenager rather than as a kid, as well as specifying that it was Obi Wan alone who sought out Anakin.
