Fan CastingMan of Steel

The infant Kal-El is rocketed away from his doomed planet, Krypton, which explodes. He gets sent to Earth, where he is found by Jonathan and Martha Kent. He grows up feeling alone and isolated, but through his parents, he has an optimistic viewpoint on life and good morals. As well as having powers he simply doesn't understand. After his father dies of a stroke, he moves to Metropolis where he hopes to find some semblance of purpose. It's during this time where General Zod, a being from his home world, finds out the son of Jor-El (the man who imprisoned him in the Phantom Zone on Krypton) is on Earth. So, he tries to build a New Krypton while also taking vengeance on the man who imprisoned him through Kal-El. The Man of Steel is the only thing in between Zod and annihilation.
