Superman decides to remove all nuclear weapons from the earth, for the sake of world peace. His actions, however, kickstart a chain of events that may leave the world in pieces!

Mashup of Christopher Reeve Superman sequels II, II Donner Cut, III, and IV into one 3-hour film, like a greatest hits package. Inspired by Grant Morrison's All-Star Superman comic storyline.
Serves as a direct follow up to Superman 1978.
Both Lester and Donner scenes of Clark revealing his identity to Lois from Superman II are rejected, in favor of the apartment scene from Superman IV.
Richard Pryor’s character Gus is changed to a cybercriminal scheming with his “friends”, and who also just happens to be a big fan of Superman.
Scenes are rearranged to suggest Nuclear Man causes Superman to turn "Evil" and the Phantom Zone to break.

Clark Kent must reconnect with his past in order to defeat the corruption of his own vanity as the Man of Steel. He must also stop the potentially world ending plot of Lex Luthor who hopes to rule mankind through manipulating the nuclear arms market and making an evil clone of Superman. Will Clark force the world into peace and become the very despot his father imprisoned on Krypton, or will he achieve victory though the humble small-town morals of truth, justice, and the American way?
