Superman Lives is one of the most tantalizing 'what-ifs' in comic-book movie history. After Tim Burton reinvigorated Batman and made countless millions for Warner Bros., hopes were high that he could do the same for Superman. Partially adapting "The Death and Return of Superman" arc from the comics - a hugely significant story - the film would have found Nicolas Cage's Man of Steel alienated by humanity, while simultaneously battling Lex Luthor, Brainiac and Doomsday.
