Thor Comic-Con Trailer

There was a 5-minute trailer for Thor shown at Comic-Con last week and it got leaked online today. I don't really know much about Thor except for what the "premise" section of Wikipedia had to say...

"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."

The trailer is pretty badass but the movie doesn't come out until May 2011. Chris Hemsworth (the brother of that guy who's dating Miley Cyrus), Natalie Portman and Anthony Hopkins star in the movie.
