I doubt they would have time travelled at the end of both movies, which means that the time travel at the end of movie one only happened because movie two shit the bed.
What was the original non time travel end to the Superman The Movie?
My understanding is that the time travel ending was originally intended for the second film, but plans changed, and it was folded into the first film. I'm afraid I just don't know enough about what went on that caused all of the changes. Money and time I suspect were the issues? Apologies, I could be totally wrong about everything, here.
One thing I like about the Donner Cut of S(II), the thing I like most actually, maybe even love, is how Superman tossing the first missile into space is what frees Zod and gang from the Phantom Zone. No need for the Eiffel Tower sequence, eh. I originally streamed the Cut cold, so that connection and plot sequence were a quite an eye-opener for me. It seems plausible that that was the original intention, but whether it was, how the detonation of the other missile would have played out, and whether there were originally even supposed to be two missiles, I haven't a clue. Was the first film to have ended on the cliffhanger of the super-villains being freed? I'm sorry, I don't know.
I apologize, I can't go down the rabbit hole of figuring it all out right now, researching and vetting sources. But if anyone does know what the original intention was for the two Donner films, I'd definitely like to know, too.
Also that trucker deserved what he got, and Superman is not above giving an asshole their comeuppance.He didn't torture Zod (or kill him, as they filmed scenes of Zod's gang being arrested so the film's intention was not for Zod and co to be dead). Also its fine to protect his secret identity, he didn't "violate" anything (certainly not any more then, say, Professor X would do casually), erasing a memory is extreme but justified in the context of a superhero world and its not like he did it on a whim.
The irony that "betterhelp" has a terrible reputation just makes this comment more ridiculous. If someone wanting Superman to be the main character in Superman stories bothers you I really think that's your problem.
