I know you're probably tired of reading breakdowns of this trailer, but I'm hoping you'll be willing to stand one more. Anyways, here goes nothing.
Well I'm trying to think of something clever to say but all I can come up with is... "WOW." I mean that was epic. I had been away from my computer for a week when this came out and so when I got home, I had the best surprise ever! Okay, enough about me. Let's talk about that trailer. That's why you're reading this, isn't it?
"Today...is a day for truth. The world needs to know what happened. And to know what he stands for. That kind of power is very dangerous."
We open with this rather depressing dialogue from Senator Finch. We witness Superman floating outside what appears to be the Capitol Building while a group of protestors hold up signs such as "Superman = Illegal Alien" "This is OUR world, not YOURS" and "Earth belongs to humans".
Superman enters the Senate Chamber and receives dirty looks from every direction.
The scene shifts to Bruce Wayne in the streets of Metropolis, watching helplessly as a Wayne Enterprises building is destroyed in Superman's fight with Zod. He runs towards the devastation and is enveloped in a cloud of dust. He is then shown comforting a little girl who presumably lost someone in that building. We hear a voiceover of Senator Finch saying, "Let the record show that this committee holds him responsible".
Next we see Bruce Wayne returning to an overgrown and dilapidated Wayne Manor, then down in the Batcave.
Wayne reads a newspaper about the destruction of Wayne Tower, upon which someone has scrawled the eerie message, "You let your family DIE". We hear Jeremy Irons Alfred repeat a portion of his line from the first trailer, "That's how it starts. The fever. The rage. That turns good men... cruel."
As he says this, we see a shot that appears to show a shirtless and bearded Batman pulling a rope attached to a tire. We jump to a shot of what is presumably Gotham City as police officers find a Batarang embedded in a wall. We hear Laurence Fishburne's Perry White say, "This bat vigilante is like a one man reign of terror." As this line concludes, we see a shirtless and bearded man, who appears to be beat up and chained to a wall. We see a bat branded on the man's shoulder.
We are next shown what is likely a flashback of young Bruce Wayne falling into the dry well where he gains his fear of bats as Perry White says to Clark Kent, "You don't get to decide what the right thing is. Nobody cares about Clark Kent taking on the Batman."
Following this, we see Lois placing her hand over Superman's emblem as she reminds him, "This means something. It's all some people have. It's all that gives them hope." Next we see Martha Kent give her bit of advice to her adoptive son: "People hate what they don't understand. Be their hero, Clark."
"Be their angel. Be their monument. Be anything they need you to be. Or be none of it. You don't owe this world a thing. You never did."
We are next shown Jesse Eisenberg's Lex Luthor saying to Senator Finch, "Do you know the oldest lie in America, Senator? Devils don't come from hell beneath us."
This is immediately followed by what appears to be Superman reluctantly kneeling before Lex Luthor.
We hear Lex say, "They come from the sky" as we are shown a body bag being unzipped to reveal the corpse of General Zod.
Next, Bruce Wayne is heard, speaking presumably to Alfred, as he is shown looking at his memorial to Jason Todd, his former Robin whom the Joker brutally murdered.
Bruce says, "20 years in Gotham. How many good guys are left? How many stayed that way?" as we are given our first look at Wonder Woman's civilian identity, Diana Prince.
Bruce continues, "He has the power to wipe out the entire human race." We see a shot of Batman activating the Batsignal as he concludes, "And we have to destroy him."
We next see the words "In 2016" followed by a montage of scenes: a diver finding something (possibly Atlantean in origin?), men on horseback, the Wayne murder and funeral, the Batwing, Lois peeking out from behind a barricade, Bruce with a determined look on his face, Diana Prince's secret identity climbing into a car, Wonder Woman causing this...
... and then we jump to Batman in what is strikingly reminiscent of WWII trenches as we hear Alfred say, "You're gonna go to war." We see Batman viciously fending off Superman's soldiers and even snapping one's neck.
Next we see the Batmobile drive past an explosion and Superman turns to the camera as Alfred continues, "He is NOT our enemy." Next we see a mystery figure riding a motorcycle into the Lexcorp headquarters.
The scene then jumps inside, where Lex appears to be examining a rather large chunk of kryptonite.
A shot of Batman's mech suit tackling Superman through a roof as Lex says, "Black and blue." Quick shot of Wonder Woman before Superman uses his heat vision and Batman uses his grappling gun to avoid it. We hear Lex's voiceover continue, "God versus man." A shot of Lois and Superman kissing changes to Lex saying, "Day versus night." Superman hovers in midair while Batman smashes through a window. Lex mockingly says, "The Red Capes are coming. The Red Capes are coming."
And we end on Superman prying apart the roof of the new Batmobile and the Dark Knight standing up for an epic staredown with the Man of Steel.
