Just released is a poster for Thor: The Dark World, in which Thor presumably gets to put the hammer down on anyone who gets in his way. The movie will be released in November of this year.
Here's the blurb:
Thor battles an ancient race of Dark Elves led by the vengeful Malekith who threatens to plunge the universe back into darkness after the events of The Avengers.
Like in the first film, joining Chris Hemsworth as Thor will be Natalie Portman, Stellan Skarsgard, Kat Dennings, Anthony Hopkins, Tom Hiddleston, and Ray Stevenson. Christopher Eccleston will play Malekith.
