Paramount Pictures has released the first theatrical trailer for Thor, starring Chris Hemsworth, Natalie Portman, Clark Gregg and Anthony Hopkins. While fans got a glimpse of most of the footage here at Comic-Con, this is the first time Marvel has released footage in a public arena. Any concerns fans may have had over the Kenneth Branagh-directed comic book adaptation will probably be mostly hushed by the awesomeness of this new teaser!

Check out the trailer below, and see the film's first official poster in our Thor pictures gallery! Thor comes to earth on May 6, 2011.
