I don’t know what he’ll find on the abandoned Earth, probably some mutant dudes and then a bunch of animal life monsters that will be impossible and just make me angry. Judging from the reasoning behind why Earth was abandoned, I’m not holding out hope for things to make a lot of sense. But I hope you like the AfterEarthSmithverse, because the studio is banking on you wanting to buy comic books, video games, and all sorts of other random crap!
A comic series called After Earth: Innocence will have some of the back story starting when Nova Prime was colonized, but even then there is backstory history all the way to 1908 and the Tunguska event. Later, the Raige family invents some stuff and becomes prominent, and then because someone writing this has a divine rights of kings fetish, thus the modern day (future) Raiges who are super generals.
Better After Earth than After Birth, I guess…
Post After Earth (after After Earth?), Will Smith is rumored to be developing a film around Cain and Abel, the biblical bros that ends in murder. Maybe this’ll answer the long-asked question as to where their wives came from! This will be Smith’s directorial debut if it goes forward.
