If the intention is to present the film as scripted, turning the world backwards is the way to go. Of course, in order for this to truly work you may want to re-cut the first film so Lois doesn’t die, thus preventing repetition; also the release of the villains took place in the first film in the original conception.

Yeah that makes sense, guess i’ll be doing a superman the movie re-edit but just change the ending so it can be truer to the script that Donner had intended.
