THOR 2 Villain to be Played by Mads Mikkelsen?

Marvel is gearing up to get Thor 2 into production, and they are currently in talks with Mads Mikkelsen (Casino Royale, Valhalla Rising) to take on the role of a villain in the story. There's no word on what villain he'll play, but it's in addition to Tom Hiddleston's Loki who will obviously have a big part in making Thor's life a living hell. Mikkelson will fit right into this world, and I think he'll make a great villain.

If cast he'll join most of the cast from the original Thor film including Chris Hemsworth, Anthony Hopkins and Natalie Portman. The sequel is being directed by Alan Taylor who worked on Game of Thrones, and from what we've heard he'll be bringing that setting and style to the world of Asgard, which will be cool to see. 

The script was written by Don Payne, who co-wrote the first draft of the first movie, and Robert Rodat is currently polishing it up. Thor 2 will be released on November 15th, 2013, and production is expected to start later this summer.

What villain do you think Mikkelsen will be playing?
