Poor Christopher Reeves. He was the greatest thing to happen to Superman since WWII, but after Superman II came out and kicked ass, he couldn’t seem to catch a break. Superman III was terrible, and just when it seemed like things couldn't get any worse, Superman IV: The Quest For Peace crash-landed in theaters.
The filmmakers' hearts were in the right place. The story revolves around Supes trying to rid the world of all of its nuclear weapons while fighting off the nefarious machinations of Lex Luthor. There was the promise of an actual message underneath, giving hope that The Quest For Peace would showcase the Man of Steel as humanity’s pacifistic savior rather than a knuckle-dragging demigod. But a minuscule budget and a creatively drained cast killed the film. Superman's cinematic self has yet to bounce back.
