The Hollywood Reporter is reporting on new additions to the Thor movie. It looks like Colm Feore and Jaimie Alexander will be part of the movie. Ms. Alexander will play Sif. I don’t know who the heck she is, but her photos look like she’s got the right basic look for Sif.
As for Feore, he is absolutely awesome in everything he does. It doesn’t matter if the movie he is in sucks, he’s still great. Let’s hope this movie doesn’t suck. That’d be a pretty amazing trick, given Kenneth Branagh is directing, and he is as close to a god as is possible outside of the Marvel universe.
