That means pre-production on Thor: The Dark World is well underway, and that the story is set in place. This sequel is said to have a stronger Norse influence, and will have a very 'Viking' centric vibe. Mads Mikkelsen was originally set to play the villain, but recently dropped out. While we don't know who is replacing him just yet, we now have an idea about whom he was set to play.
In an interview with I Review Too that dates back to early June (thanks to Comic Book Movie for digging this up), stuntman James Grogan let it slip that Thor will be going up against the The Dark Elves of Svartalfheim. Which makes sense, considering the new title revealed during Comic-Con 2012.
Here is what he had to say.
The speculation this morning is that Mads Mikkelsen had been cast to play Malekith The Accursed, ruler of the Dark Elves, and a not very friendly guy. This blue, pointed-eared super villain has super human strength and speed, along with the ability to teleport and project energy. And he looks like he would fit right into the overtly Norse universe being hyped up in this sequel. Malekith's biggest storyline in the comics, to date, finds him teaming up with Loki to retrieve the Casket of Ancient Winters, which allows its user to control the icy weather conditions on Niflheim. It also makes its user younger.
Of course, this plotline has not yet been confirmed by the studio. But it is in line with everything we've heard about the project thus far. We'll be sure to update you as the story breaks.
Thor: The Dark World was released November 8th, 2013 and stars Chris Hemsworth, Natalie Portman, Tom Hiddleston, Anthony Hopkins, Christopher Eccleston, Jaimie Alexander, Zachary Levi, Ray Stevenson. The film is directed by Alan Taylor.
