HOW WOULD I DO THE ORIGIN?
I believe it should be a mix of different stories and incarnations with little nods to everything.
It should be an origin in an non-liner way, different than what was done in S:TM.
We should first meet Clark when he's traveling around the world to solve problems and something attracts him to Metropolis. Something plausible. In my script, We first find him secretly helping people survive through a war in Caznia (A little nod to TAS and Peace on Earth). He would be bringing food to the helpless, protecting innocent people without actually interfering in thematic things. However, one side of the war starts to win fast because of advanced weapons. Lois is there covering it all with Jimmy taking photos of the destruction too. She suspects there is going to be some kind of a weapon deal between a terrorist faction from Caznia and some unknown people in the Harbour so she goes there to check. Clark is listening to it all and go there too and stops the transaction, taking care of the terrorists. Eventually, he manages to trace it all back to Metropolis and that's the reason he goes there in the first place.
Eventually the war is over but the side-effects are numerous. Countless injured, homeless,etc. Clark wonders if he is doing the right thing to act in secret. He thinks he needs to be something more, an exemple, a symbol. So he goes to Smallville to create the Superman idenitity with his parents. As he comes back to Smallville, he remembers his creation and learnings from his childhood, all done in flashbacks. Little nods to the Tornado sequence, Lana, Pete Ross and Superman for all seasons.
This is a way i found out to kinda put together Birthright, TAs, Superman for all seasons, Man of steel and various other stories from the comics and make it completely new and different than Donner's origin.
