Marvel has released gorgeous concept art from Thor of Bifrost, the rainbow bridge connecting Asgard to Earth. The image can be unlocked and downloaded from a new interactive guide to "The Universe of Thor," which you can check out below (courtesy of the movie's U.K. site, hence the April 27 date).
Paramount Pictures and Marvel Entertainment present the epic adventure, Thor, which spans the Marvel Universe from present day Earth to the realm of Asgard. At the center of the story is the mighty Thor (Chris Hemsworth), a powerful but arrogant warrior whose reckless actions reignite an ancient war. Thor is cast down to Earth by his father Odin (Anthony Hopkins) and is forced to live among humans. A beautiful, young scientist, Jane Foster (Natalie Portman), has a profound effect on Thor, as she ultimately becomes his first love. It’s while here on Earth that 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.
Directed by Kenneth Branagh, Thor stars Chris Hemsworth, Natalie Portman, Anthony Hopkins, Tom Hiddleston, Jaimie Alexander, Colm Feore, Stellan Skarsgård, Kat Dennings Joshua Dallas, Tadanobu Asano, Ray Stevenson, Idris Elba, Rene Russo, Clark Gregg and Samuel L. Jackson. Thor opens in the United States on May 6.
