Updated September 12: And the posters keep coming. Thursday Marvel released a new Thor: The Dark World poster featuring Anthony Hopkins as Odin. Click on the image above to see the full poster.
Update September 9: Another Thor: The Dark World poster today, this one apparently a digitally painted depiction of Thor and Jane Foster (Chris Hemsworth and Natalie Portman, respectively). It's either digitally painted, or a very odd angle for Portman, whose features look a bit different.
Original Story: Marvel Studios has revealed the latest poster for Thor: The Dark World, a character-focused poster featuring the main villain of the film, Malekith the Accursed. The leader of the dark elves, Malekith (played by Chris Eccleston) will team with Loki in some capacity in the film, causing major problems for Thor, Asgard, and of course us lowly Midgardians.
Thor: The Dark World, the second movie in "Phase 2" of the Avengers films from Marvel Studios, hits theaters November 8, 2013.
