Last week, we brought you Chris Hemsworth’s thoughts on the sibling rivalry between his character, Thor, and his adopted little brother Loki (Tom Hiddleston) and how this dynamic continues to evolve into Thor 2. Now, it looks like Loki will be getting some company to antagonize Thor in this sequel.

Variety reports that Walt Disney Pictures and Marvel Studios is negotiating with Mads Mikkelsen (The Hunt, Casino Royale) to star as “one of the villains” in the Alan Taylor (Game of Thrones) helmed sequel with script by Don Payne (Thor, Fantastic 4: Rise of the Silver Surfer) and Robert Rodat (Falling Skies, Saving Private Ryan.)

Thor 2 will begin production late this summer and is slated to hit theaters on November 15th, 2013.
