Plot Details

The official synopsis indicates that Superman will tell the story of Superman's journey to reconcile his Kryptonian origins with his human upbringing as Clark Kent. He is the embodiment of truth, justice, and the American way, guided by human kindness in a world that sees kindness as old-fashioned. The film is set to explore a world where superheroes already exist, and Superman is finding his place among them, particularly with other established heroes and anti-heroes like The Authority.
