Just last week we posted a behind-the-scenes http://movieweb.com/new-video-from-the-set-of-marvels-thor/video from the set of Thor (via Entertainment Tonight). A new TV version of that clip is a hair longer and gives us our first look at Jaimie Alexander as Sif. Check out the stills below!

At the center of the story is The Mighty Thor, a powerful but arrogant warrior whose reckless actions reignite an ancient war. Thor is cast down to Earth and forced to live among humans as punishment. Once here, Thor learns what it takes to be a true hero when the most dangerous villain of his world sends the darkest forces of Asgard to invade Earth.
