Proving that a hero is often only as good as his nemesis, the fourth Man of Steel trailer promises legit villainy in the form of Michael Shannon as General Zod. The Kryptonian warlord delivers an ominous ultimatum to the people of earth, demanding that they surrender Superman to him: "My name is General Zod. I have journeyed across an ocean of stars to reach you. Your world has sheltered one of my citizens. He will look like you, but he is not one of you. To those of you who know of his location, the fate of your planet rests in your hands. To Kal-El, I say this: surrender within 24 hours, or watch this world suffer the consequences."

Zod's speech is punctuated by a venomous threat from his right-hand woman, Faora (Antje Traue, Pandorum), to Superman: "You will not win. For every human you save, we will kill a million more."

One point of logic that fans have long debated is the question of how, exactly, Superman shaves--if he is impervious to fire, explosions, and extreme temperatures, then surely no razor could hope to trim his Kryptonian whiskers. In light of this, and the fact that the Man of Steel trailers have featured a noticeably bearded Clark Kent, Gillette came up with a fun series of videos in which celebrity pundits proposed their own theories...

Two versions of the teaser trailer for the Superman reboot Man of Steel made their theatrical debut ahead of The Dark Knight Rises. Both contain the same footage, but feature different voiceover narration.

In the first, Superman's biological Kryptonian father Jor-El (played by Russell Crowe) delivers an inspirational message on his son's destiny to face adversity and shepherd humanity to its full potential: "You will give the people an ideal to strive towards. They'll race behind you, they will stumble, they will fall. But in time, they will join you in the sun. In time, you will help them accomplish wonders."

In the second, Superman's adoptive human father Jonathan Kent (played by Kevin Costner) takes a more practical approach and plants the seeds of down-home values in his young alien son: "You're not just anyone. One day, you're gonna have to make a choice. You have to decide what kind of man you want to grow up to be. Whoever that man is, good character or bad, he's gonna change the world."
