Trailer opens with Henry Cavill as Clark Kent under the water. This could be a result of an explosion; we've seen set photos with Cavill seemingly trying to save a boat. It's also a Christ-Like pose.
From there we get a voice-over from Clark when is he just a boy. Clark is in school and runs away. He hides in a closet and cover his ears, which could be the advent of his super hearing due to the writing on the chalk board. Ma Kent is trying to calm him (and his powers?)
Next, the Comic-Con bus scene is shown, and something that Cosmic Book News first told you about months ago. Clark uses his powers to save a life, with someone noticing.
Next, Kevin Costner talks about how Clark needs to keep this side of himself a secret, with Pa Kent even saying that maybe he should have let who he saved die (I believe this is foreshadowing the difference between Pa Kent and Jor-El).
Then Clark is seen inside something? A spaceship? He has so many questions. New Fortress of Solitude (which could be the crashed spaceship)?
Now, Henry Cavill is walking on the ice (from the Fortress?) revealed as Superman (similar with Christopher Reeve who flew off).
And off Cavill goes in the "sonic boom!" Perhaps flying for the first time?
And we see Superman go cosmic as he flies through Earth's orbit and space! Another nod to Christopher Reeve!
Next we see a brief scene featuring what looks like an explosion with a light beam. It's rather quick. From there we are taken to baby Kal-El with Russell Crowe and Aylet Zurer.
More Comic-Con footage is shown with Cavill on fire (most likely related to the first scene of Cavill underwater).
Another really quick clip is shown, two ships fighting? Which leads us into a spaceship! In Smallville! Is it Zod looking for Clark?!
Zod is then revealed!
With Superman kneeling before Zod!
Laurence Fishburne is running from the collapsing - Daily Planet!
Someone watches from their spaceship as something explodes? Daily Planet? A doomed Krypton?!
More Comic-Con footage, Superman vs. Zod. And then another clip of the Spaceship!
And a first look at Christopher Meloni as Colonel Hardy and Richard Schiff as Dr. Emil Hamilton!
Pa Kent is shown kissing his son, perhaps pondering his son's future.
Cavill holds a boy in his arm with a torando following from behind! Possibly the first burst of super speed for Henry Cavill!
Next! Our first words from the new Superman, Henry Cavill! And it sounds a lot like Christopher Reeve! Amy Adams as Lois Lane!
Is the world ready for Superman the Man of Steel?
