Fan Casting The Justice League.

our justice league movie opens exactly where the last superman movie left off. superman is in a coma following a near-fatal confrontation with lex luthor at his kryptonite power plant, but four of earth's most powerful burgeoning metahumans—batman, wonder woman, the flash and green lantern—have come to stand vigil by his bedside as he recovers. soon afterward, green lantern (whose power ring allows him to instantly identify any alien's species) suddenly comes to a startling realization about superman's true origins: he's a kryptonian, a member of an advanced alien species who were nearly driven to extinction after their planet was destroyed by the forces of the planet apokolips. ever since the fateful day that krypton was destroyed, the green lantern corps has been preparing for the day that the legions of apokolips might attack another inhabited world, and they have reason to believe that day is drawing near. meanwhile, superman's foe lex luthor has secretly obtained a powerful alien supercomputer called "the mother box", and he has since been tormented by nightmarish visions of an extraterrestrial invasion from "the world of blood and fire". but since the mother box only showed him a partial fragment of a larger vision, luthor misinterpreted it, and mistakenly believes that superman is the alien invader that his vision warmed him about.
