If you haven't picked up the GotG disc yet, you can get a sneak peek at the footage right here. Marvel released a brief teaser of the Blu-ray extra, and it's a must-see. In the 30 second clip we can spot Elizabeth Olsen as Scarlet Witch and Aaron Taylor Johnson as Quicksilver, along with Thor, Black Widow and Captain America. Director Joss Whedon also offers a few choice comments on the action, as well.
By the way, you can grab Guardians of the Galaxy (3D Blu-ray + Blu-ray + Digital Copy) right now, if you want.
