Two long standing actors have joined the cast for Thor: The Dark World.
Starting off we have Richard Brake (Batman Begins) who has been cast as the captain of the Einherjar warriors. In the Marvel universe the warriors, led by Ander, are responsible for the training of Thor. It is unclear whether Brake is playing the role of Ander but he has been officially added.
The other person added is Clive Russell (Sherlock Holmes, Game of Thrones). He will be playing Tyr who is Thor's older brother and Asgard's God of War.
