This is the first MAN OF STEEL trailer. I've heard that it isn't currently playing before the Dark Knight Rises. (No trailers played during my IMAX viewing.) There isn't much to see, but it hints that something HUGE is coming. There are two trailers that show the same thing, but one is with Jonathan "Pa" Kent's (Kevin Costner) speech and the other is (Superman's biological father) Jor-El 's (Russell Crowe) speech.
"You're not just anyone. One day, you're going to 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"
"You will give the people an ideal to strive towards. They will rise behind you. They will stumble. They will fall. And in time, they will join you in the sun. In time, you will help them accomplish wonders."
