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

Things I noticed:

Another creepy rendition of "I've Got No Strings", though this one has piano plucks instead of demon child singing.

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, right after Thor shoots that blue lightning bolt. It's Loki.
