'Thor: The Dark World' Trailer: Hammer Time

[From MTVWith "Iron Man 3" a little more than a week away, Marvel has already given us a look at our next trip to the universe of superheroes and villains. The first teaser trailer for "Thor: The Dark World" premiered in the early hours of the morning, and even though the preview clocks in at just under two minutes, we can already see a much different adventure for the Norse god.

"Thor: The Dark World" picks up after the events of "The Avengers." Thor (Chris Hemsworth) has returned home to Asgard, but a new force threatens both the god's home world and Earth. As it's revealed near the end of the trailer, Thor must turn to his brother and rival Loki (Tom Hiddleston) for assistance when trying to save the Nine Realms from the dark elves.

Natalie Portman makes a welcome return to the Marvel universe as Jane Foster, Thor's Earth-bound love, who finds herself in Asgard shortly after the start of the preview. A menacing voice over from the film's main baddie, the dark elf Malekith, played by "G.I. Joe: The Rise of Cobra" actor Christopher Eccleston, suggests that Jane may stand directly in harm's way with only Thor to protect her.
