First Look At The Cosmic Cube!

The Cosmic Cube is well known in the Marvel U. as being a major pain in the ass. It's a "cosmic containment device capable of altering reality", so basically you don't want this thing getting into the wrong hands. Well, SuperHeroHype has a pic released from Captain America: The First Avenger, and yea, that just happened:

Now, in the comics, pretty much everybody and their grandmother has had access to one or more Cosmic Cubes, and a few of them have even evolved into sentient beings. In the MCU (Marvel Cinematic Universe) The Cube (or Tesseract) is a Norse mythological device that Johann Schmidt/Red Skull (played by Hugo Weaving, natch) is searching for, and apparently finds. A nice tie in to Thor to really drive home the point that all of these movies and characters exist in the same universe.

That being said, expect the Cube to pop up somewhere in Thor as another easter egg, like Cap's shield in Iron Man.
