Over the weekend, news broke that Chris Hemsworth (who played George Kirk in Star Trek) had been cast as Thor in Kenneth Branagh’s big screen adaptation of Marvel’s Thor and the Summer 2012 superhero team-up film The Avengers. Nikki Finke is reporting that British actor Tom Hiddleston, who is almost a complete unknown to American audiences, has been cast as Thor’s nemesis Loki. Of course, the actor has ties to director Branagh, who starred with him in Ivanov on the London stage and the BBC miniseries Wallander. Hiddleston was also one of the actors on the short list being considered for the part of Thor, which should tell you something.
