Anthony Hopkins has been officially added to the cast of Thor in the role of Odin, according to Variety. Odin is the father to Thor and Loki, played by Chris Hemsworth and Tom Hiddleston, respectively. Also in the cast are Natalie Portman, Jamie Alexander and Colme Feore. Kenneth Branagh is directing from a script by Mark Protosevich, Zack Stentz and Ashley Miller.
The film’s plot will involve Thor, a powerful yet arrogant warrior, being banished from Asgard to Earth after accidentally reigniting an ancient war. It’s not long before the dark forces of Asgard, presumably lead by Loki and Feore’s villainous role, turn their attentions to humanity leaving Thor to rise to the occasion.
Production is scheduled to begin in January with a release date of May 20th, 2011.
