Not as shocking as the first trailer, but still extremely and suitably creepy.

Things I noticed:

Andy Serkis' character with a gun. The look on his face basically proves he's a villain, but whether he's Klaw or not has yet to be seen.

There's a shadowy man at one point, shortly after Ultron uses the red lightning. And it looks like... LOKI.
