Fan Casting Superman: The Man of Steel (2009)

The premise in early outlines by Michael Dougherty and Dan Harris concerned the sun-stone island that Superman hurled into outer space. As the large mass of Kryptonian technology continues to grow, it attracts Brainiac to the Milky Way, having first become aware of Superman when one of his probes surveyed him during his five-year trip in the crystal spacecraft exploring the lost remnants of Krypton. When Brainiac's spacecraft arrives, Superman greets him, with Brainiac deceiving him by appearing to be an ordinary Kryptonian survivor like him, asking why he hasn't re-educated Earth's natives to improve their lifestyle. Superman explains he has sworn not to interfere with the natural progress of human society, but Brainiac disagrees and begins to interact with various nations, eventually causing wars to break out. As a result, Superman becomes a pariah and investigates the innards of Brainiac's ship, finding an army of clone bodies that resemble the visitor and learning that he is actually a ruthless artificial intelligence that's responsible for Krypton's doom. Brainiac has chosen Jason White, Superman's biological son with Lois Lane, as his genetic host, causing him to rapidly age into full adulthood, thus Superman finds he has no choice but to sacrifice his only son in order to put an end to the threat of Brainiac.
