So the teaser trailer was shown at SDCC and so was this teaser poster, posted, here.
You know how in the “Dark Knight: Rises” teaser posters, you see a hint of Superman on them, mysteriously? Well, Nolan has done it again with the Superman “Man of Steel” poster, but this time, there’s some Batman secrecy on the “MOS”, poster. Look closely, the shining light on Supe’s chest. Does that shining light remind you of something? Yep, that’s right. That shining light is a shape of a Bat.
I hope I’m not that first one that noticed this?
