I’m not sure Paramount/Marvel are too happy about this, but the full Comic-Con trailer for Kenneth Branagh‘s Thor has made its way online. The superhero blockbuster stars Chris Hemsworth, Natalie Portman, Kat Dennings, Anthony Hopkins, Idris Elba, Stellan Skarsgård, Tom Hiddleston and Ray Stevenson. You can check out the 5 minute video below in the best quality that’s been released.

UPDATE: The official Thor trailer is now available here.

Plot: Marvel Studios expands its film universe with a new type of superhero: THOR. This epic adventure spans the Marvel Universe; from present day Earth to the realm of Asgard. 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. Kenneth Branagh directs this fantasy epic which stars Australian actor Chris Hemsworth as the ancient Norse god, Tom Hiddleston as his evil brother Loki, Natalie Portman as Jane Foster, a young woman who befriends Thor on Earth, and Anthony Hopkins as Odin, Thor’s father and king of Asgard. Expect to see agents of S.H.I.E.L.D., previously seen in ”Iron Man,” to make an appearance, further forshadowing the coming of The Avengers!

Thor hits theaters May 6th, 2011.
